Description

Technical Field

[0001] This utility model relates to the field of paper product technology, and in particular to a paper product composite core cutting device. Background Technology

[0002] Paper composite cores, also known as third-generation hybrid cores (currently updated and iterated), are structures made of cleanroom paper, non-woven fabric, and absorbent resin through mechanical pressing. This core structure is compact, remains flat after absorbing water, and is not prone to clumping or tearing.

[0003] As described in announcement number CN212919546U, a cutting device with a measuring structure for paper product production includes a main body of the cutting device. A baffle is vertically mounted on the upper part of the main body, and a pair of support columns are symmetrically arranged on the upper part of the main body. A crossbeam is provided on one side of each support column, and a lifting device is mounted on the crossbeam. A lifting plate is located below the lifting device, and a cutting blade is located at the bottom of the lifting plate. A fixing block is located on the upper part of the main body of the cutting device. The scale provided in this invention can cut finished products of a set size during paper product cutting. Common cutting devices often lack a measuring structure, resulting in inaccurate cutting dimensions of the cardboard, thus affecting the usability of the cut cardboard. The fixing plate added to the worktable addresses this issue. During paper product cutting, metal items such as pins are often used, which can easily damage the integrity of the paper product. The fixing block can hold the paper product to be cut in place.

[0004] This patent can be equipped with a measuring structure, which can improve the accuracy of cardboard cutting dimensions. However, existing devices can cut cardboard of different widths according to actual production needs, and their practicality and flexibility need to be improved.

[0005] Therefore, we propose a novel paper product composite core cutting device. Utility Model Content

[0006] The purpose of this invention is to solve the problem that existing devices cannot cut cardboard of different widths according to actual production needs, thus lacking practicality and flexibility.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a paper product composite core cutting device, comprising an operating table, with movable cutting components connected to both sides of the operating table, the movable cutting components comprising two sets of electric slide rails, the two sets of electric slide rails being respectively connected to the outer surfaces of both sides of the operating table, support frames being connected to the surfaces of the two sets of electric slide rails, two sets of electric push rods being inserted into the top of the support frames, the output ends of the two sets of electric push rods being connected to a connecting frame, a servo motor being connected to the top center of the connecting frame, a first gear being connected to the output end of the servo motor, a second gear being connected to the bottom surface of the first gear, a bidirectional screw being inserted into the inside of the connecting frame, movable blocks being connected to both sides of the bidirectional screw, threaded holes being opened inside the movable blocks, fixed blocks being connected to the bottom of both sets of movable blocks, a cutting blade being inserted into the bottom of the fixed block, a hole being opened inside the cutting blade, a magnetic suction rod being inserted into the hole, and bearings being connected to both ends of the bidirectional screw.

[0008] Furthermore, the two sets of electric push rods are controlled by the same set of switches, and the position and size of the first gear match the position and size of the second gear.

[0009] Furthermore, a third set of fixing blocks is connected to the bottom center of the support frame, and the magnetic insertion rod passes through the fixing block to form an insertion connection with the hole.

[0010] Furthermore, the movable block is connected to the bidirectional screw via a threaded hole.

[0011] Furthermore, stabilizing components are connected to the four bottom corners of the fixing block. Each stabilizing component includes a sleeve, inside which a spring is installed, and a top block is connected to the bottom of the spring.

[0012] Furthermore, top plates are connected to both sides of the bottom of the top block, and rollers are connected between the bottoms of the two sets of top plates, forming an elastic structure between the top block and the spring.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when it is necessary to cut cardboard of different widths, the bidirectional screw can be driven to rotate by starting the servo motor, thereby adjusting the distance between the two cutting blades by rotating the screw thread, while the position of the middle cutting blade remains unchanged. In this way, cardboard of different widths can be cut according to actual needs, improving the practicality and flexibility of cutting.

[0015] 2. In this utility model, while cutting the cardboard, the rollers are pressed tightly against the surface of the cardboard by the spring, which improves the stability of the cardboard during cutting and prevents the cardboard from shifting and causing defective products to be cut, thereby improving the pass rate of cardboard production.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1 - Figure 4As shown, this utility model provides a paper product composite core cutting device, including an operating table 1. Moving cutting components 2 are connected to both sides of the operating table 1. Each moving cutting component 2 includes two sets of electric slide rails 201, which are respectively connected to the outer surfaces of both sides of the operating table 1. Support frames 202 are connected to the surfaces of the two sets of electric slide rails 201. Two sets of electric push rods 203 are inserted into the top of the support frames 202. Connecting frames 204 are connected to the output ends of the two sets of electric push rods 203. A servo motor 205 is connected to the center of the top of the connecting frame 204. A first gear 206 is connected to the output end of the servo motor 205. A second gear 208 is connected to the bottom surface of the first gear 206. A bidirectional screw 207 is inserted inside the connecting frame 204. Both sides of the bidirectional screw 207 are connected to... A movable block 210 is connected to the bottom of each of the two movable blocks 210. A cutting blade 213 is inserted into the bottom of the fixed block 212. A hole 214 is opened inside the cutting blade 213. A magnetic rod 215 is inserted into the hole 214. Bearings 209 are connected to both ends of the bidirectional screw 207. The two sets of electric push rods 203 are the same set of control switches. The position and size of the first gear 206 match the position and size of the second gear 208. A third set of fixed blocks 212 is connected to the bottom center of the support frame 202. The magnetic rod 215 passes through the fixed block 212 and forms an insertion connection with the hole 214. The movable block 210 is threadedly connected to the bidirectional screw 207 through the threaded hole 211.

[0025] The overall effect of Embodiment 1 is as follows: when cutting cardboard, the cardboard to be cut can be placed on the surface of the operating table 1. Then, the spacing between the cutting blades 213 can be adjusted according to the actual situation. When adjusting the spacing, the servo motor 205 can be turned on to drive the first gear 206 to rotate. When the first gear 206 rotates, it can drive the second gear 208 to mesh and rotate, thereby driving the bidirectional screw 207 to rotate. When the bidirectional screw 207 rotates, it will simultaneously rotate with the two sets of moving blocks 210 through the threaded hole 211. By rotating the thread, the position of the cutting blades 213 on both sides can be adjusted. At the same time, the front end of the fixed block 212 is also provided with a pointer. The spacing between the cutting blades 213 can be observed through the scale at the front end of the connecting frame 204. After adjusting the spacing, the servo motor 205 can be turned off. Then, the electric push rod 203 pushes the connecting frame 204 downward, thereby driving the three sets of cutting blades 213 downward simultaneously. Once inserted into the cardboard, the electric slide rail 201 can be activated to drive the three sets of cutting blades 213 to cut the cardboard. After cutting, the electric push rod 203 can be used to retract and drive the three sets of cutting blades 213 upward. When it is necessary to adjust the distance between the two cutting blades 213, the reverse screw of the servo motor 205 can be activated to rotate in the opposite direction. The reverse screw rotation drives the bidirectional screw 207 to reverse. The position of the cutting blades 213 can be adjusted according to the actual situation. When the cutting blades 213 are severely worn after long-term use and need to be replaced, the magnetic insertion rod 215 can be pulled out directly, and the cutting blades 213 can be removed directly from the bottom of the fixing block 212 to complete the disassembly. The new cutting blades 213 can be pushed into the bottom of the fixing block 212, and the magnetic insertion rod 215 can be inserted into the hole 214 through the fixing block 212. In this way, cardboard of different widths can be cut according to actual needs, improving the practicality and flexibility of cutting.

[0026] Example 2, as Figure 1 and Figure 5 As shown, a stabilizing component 3 is connected to each of the four bottom corners of the fixing block 212. The stabilizing component 3 includes a sleeve 301, a spring 302 is provided inside the sleeve 301, a top block 303 is connected to the bottom of the spring 302, and a top plate 304 is connected to both sides of the bottom of the top block 303. A roller 305 is connected between the bottoms of the two sets of top plates 304. The top block 303 and the spring 302 form an elastic structure.

[0027] The effect achieved by the entire embodiment 2 is that while the cardboard is being cut, the roller 305 moves downward along with the cutting blade 213. When the roller 305 contacts the cardboard, the cutting blade 213 continues to move downward, causing the spring 302 to press against the top block 303, so that the roller 305 is pressed tightly against the surface of the cardboard. Then, when the cutting blade 213 moves to cut, it will drive the roller 305 to roll on the surface of the cardboard, which plays a fixing role and improves the stability of the cardboard during cutting, so as to avoid the problem of the carton shifting and cutting out defective products, thereby improving the pass rate of cardboard production.

[0028] Working principle: When it is necessary to cut cardboard of different widths, the servo motor 205 can be started to drive the bidirectional screw 207 to rotate, thereby adjusting the distance between the two cutting blades 213 by rotating the screw. The position of the middle cutting blade 213 remains unchanged. In this way, cardboard of different widths can be cut according to actual needs, improving the practicality and flexibility of cutting. While cutting the cardboard, the roller 305 will be pressed tightly against the surface of the cardboard by the spring 302, improving the stability of the cardboard during cutting and preventing the cardboard from shifting and causing defective products to be cut, thus improving the pass rate of cardboard production.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
