Description

Technical Field

[0001] This utility model relates to the technical field of yellow paper slitting devices, and in particular to a quantitative slitting device for yellow paper processing. Background Art

[0002] Quantitative slitting usually refers to the process of cutting or separating continuous materials according to specific, preset quantities or sizes in manufacturing or material handling. Quantitative slitting of yellow paper usually involves the process of precisely cutting yellow paper materials to specific sizes and quantities.

[0003] The current quantitative slitting of yellow paper generally involves placing stacked yellow paper on a platform and pushing it with a belt conveyor to determine the cutting position of the cutting equipment. Due to the inertia of the yellow paper itself, the relatively loose yellow paper may tilt to a certain extent during the movement of the belt conveyor, which reduces the slitting accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a quantitative slitting device for yellow paper processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quantitative slitting device for yellow paper processing, comprising a platform mounted on a slide rail of the yellow paper slitting device, an adjustment component provided inside the platform, the adjustment component including a support mechanism, a rectangular hole opened on the top side of the platform, the support mechanism disposed in the rectangular hole, a driving mechanism provided above the rectangular hole, and a positioning mechanism provided on the driving mechanism.

[0006] Preferably, the support mechanism includes a soft strip disposed within a rectangular hole, with the top side of the soft strip coplanar with the top side of the platform. The left end of the soft strip is clearance-fitted with the inner wall of the rectangular hole. Two round rods are disposed opposite each other within the soft strip, with the outer peripheral wall of each round rod contacting the inner wall of the soft strip. Both ends of the round rods extend outside the rectangular hole and are rotatably connected to the platform via bearings.

[0007] Preferably, a support plate is provided between the two round rods, and the left and right ends of the support plate are in contact with the outer peripheral walls of the two round rods respectively. The top side of the support plate is in contact with the inner wall of the soft strip, and the front and rear ends of the support plate are fixedly connected to the inner wall of the rectangular hole.

[0008] Preferably, the driving mechanism includes a driving roller, which is located directly above the left end round rod and is in clearance fit with the soft belt. Two limiting plates are rotatably sleeved at both ends of the driving roller, and a driver is fixedly installed on the front side of the front limiting plate, and the driving end of the driver is fixedly connected to the front end of the driving roller.

[0009] Preferably, two square rods are slidably installed on the platform, and the top of each square rod is fixedly connected to the bottom side of the corresponding limiting plate. A motor is provided on the bottom side of the square rod, and the motor is fixedly connected to the platform through a connecting rod. A threaded rod is installed through the internal thread of the square rod, and the driving end of the motor is fixedly connected to the bottom end of the corresponding threaded rod.

[0010] Preferably, the positioning mechanism includes a pressure plate disposed between two limiting plates. Guide grooves are provided on the opposite surfaces of the two limiting plates at positions corresponding to the pressure plate. Both ends of the pressure plate are inserted into the two guide grooves and contact the inner walls of the corresponding guide grooves. The right side of the pressure plate is coplanar with the inner wall of the left end of the rectangular hole. An electric telescopic rod is fixedly installed on the top side of the limiting plate. The driving end of the electric telescopic rod is inserted into the corresponding guide groove and fixedly connected to the corresponding end of the pressure plate. The push rod of the electric telescopic rod is slidably connected to the corresponding limiting plate.

[0011] This utility model has the following beneficial effects:

[0012] When this improved yellow paper slitting device is in use, the support mechanism and drive mechanism clamp and push the yellow paper to adjust its position, thereby avoiding the yellow paper tilting due to inertia during movement, which would reduce the cutting accuracy of the yellow paper ring. After the yellow paper is positioned, the positioning mechanism is activated to work with the platform to clamp and limit the yellow paper. This, together with the support mechanism and drive mechanism, prevents the yellow paper from wrinkling at the cutting part due to the mutual collision of the cutters when the cutters are cutting, which would reduce the cutting accuracy of the yellow paper.

[0019] To make the technical solution and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] This utility model provides a technical solution: (Refer to...) Figure 1-4 The present invention discloses a quantitative slitting device for yellow paper processing, including a platform 1 installed on the slide of the yellow paper slitting device, an adjustment component 2 provided in the platform 1, the adjustment component 2 including a support mechanism 22, a rectangular hole 21 opened on the top side of the platform 1, the support mechanism 22 is located in the rectangular hole 21, a driving mechanism 23 is provided above the rectangular hole 21, and a positioning mechanism 3 is provided on the driving mechanism 23.

[0021] In this embodiment, when using the improved yellow paper cutting device, the operator first places the stacked yellow paper on the support mechanism 22, with the ends of the yellow paper positioned below the positioning mechanism 3. Then, the positioning mechanism 3, in conjunction with the platform 1 and the drive mechanism 23, works with the support mechanism 22 to clamp and limit the yellow paper on both sides of the cutter. Subsequently, the operator pushes the platform 1 to slide within the yellow paper cutting device, and the cutter passes through the gap between the support mechanism 22 and the inner wall of the rectangular hole 21, completing the yellow paper cutting process and cutting off the ends of the yellow paper. Then, the drive mechanism 23 drives the stacked yellow paper towards the positioning mechanism 3 while ensuring the yellow paper is clamped and limited, so that a specific length of yellow paper passes over the cutter. Then, the positioning mechanism 3 completes the clamping and limiting of the yellow paper again, and completes the yellow paper cutting process as described above, thereby cutting off yellow paper of a specific size from the stacked yellow paper. Then, the positioning mechanism 3 is activated to release the clamping and positioning state of the yellow paper, and the operator can directly remove the cut yellow paper from the platform 1.

[0022] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2As shown, the support mechanism 22 includes a soft belt 221, which is disposed in the rectangular hole 21. The top side of the soft belt 221 is coplanar with the top side of the platform 1. The left end of the soft belt 221 is clearance-fitted with the inner wall of the rectangular hole 21. Two round rods 222 are disposed opposite each other in the soft belt 221. The outer peripheral wall of each round rod 222 is in contact with the inner wall of the soft belt 221. Both ends of the round rods 222 extend to the outside of the rectangular hole 21 and are rotatably connected to the platform 1 through bearings.

[0023] In this embodiment, during the process of driving the yellow paper by the above-mentioned driving mechanism 23, due to the friction between the bottom yellow paper and the soft strip 221, the soft strip 221 rotates around the round rod 222, so as to avoid the situation where the stacked yellow paper is misaligned due to the bottom yellow paper being subjected to a reverse pulling force when the yellow paper moves.

[0024] It should be noted that the gap between the soft strip 221 and the inner wall of the rectangular hole 21 can provide space for the installation of the cutter;

[0025] It should be noted that the left side of the top of the rectangular hole 21 is curved to prevent the yellow paper from colliding with the inner wall of the rectangular hole 21 and affecting its movement.

[0026] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a support plate 223 is provided between the two round rods 222, and the left and right ends of the support plate 223 are in contact with the outer peripheral walls of the two round rods 222 respectively. The top side of the support plate 223 is in contact with the inner wall of the soft strip 221, and the front and rear ends of the support plate 223 are fixedly connected to the inner wall of the rectangular hole 21.

[0027] In this embodiment, as the soft strip 221 rotates around the drive roller 231, the top of the soft strip 221 remains flat due to the support plate 223 supporting the top of the soft strip 221. This prevents the soft bag from deforming due to the pressure of the weight of the stacked yellow paper on the soft strip 221 when the yellow paper is placed on it, which could lead to the stacked yellow paper tilting and misalignment.

[0028] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the drive mechanism 23 includes a drive roller 231, which is located directly above the left end round rod 222. The drive roller 231 is in clearance fit with the soft belt 221. Two limiting plates 232 are rotatably sleeved at both ends of the drive roller 231. A driver 233 is fixedly installed on the front side of the front limiting plate 232, and the driving end of the driver 233 is fixedly connected to the front end of the drive roller 231.

[0029] In this embodiment, after the end of the yellow paper is cut off, the driver 233 drives the drive roller 231 to rotate at a constant speed. At this time, due to the friction between the drive roller 231 and the top yellow paper, the stacked yellow paper moves towards the pressure plate 31. Due to the friction between the bottom yellow paper and the soft strip 221, the soft strip 221 rotates synchronously around the round rod 222, so that the end of the yellow paper passes through the gap between the soft strip 221 and the rectangular hole 21. The moving length of the yellow paper can be controlled according to the number of rotations of the drive roller 231. Different lengths of yellow paper can be cut as needed, which increases the applicability of the device.

[0030] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, two square rods 234 are slidably mounted on the platform 1, and the top of each square rod 234 is fixedly connected to the bottom side of the corresponding limiting plate 232. A motor 235 is provided on the bottom side of the square rod 234, and the motor 235 is fixedly connected to the platform 1 through a connecting rod. A threaded rod 236 is threaded through the square rod 234, and the driving end of the motor 235 is fixedly connected to the bottom end of the corresponding threaded rod 236.

[0031] In this embodiment, after the operator places the end of the stacked yellow paper on the platform 1, the motor 235 drives the threaded rod 236 to rotate, thereby pulling the square rod 234 downward. Due to the mutual contact between the square rod 234 and the platform 1, the square rod 234 moves up and down along a linear trajectory. The downward-moving square rod 234 simultaneously pulls the limiting plate 232 downward, thereby causing the drive roller 231 to press on the stacked yellow paper. The distance between the drive roller 231 and the soft belt 221 can be adjusted as needed, which facilitates the feeding of yellow paper.

[0032] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the positioning mechanism 3 includes a pressure plate 31, which is disposed between two limiting plates 232. Guide grooves 32 are provided on the opposite surfaces of the two limiting plates 232 at positions corresponding to the pressure plate 31. Both ends of the pressure plate 31 are inserted into the two guide grooves 32 and contact the inner walls of the corresponding guide grooves 32. The right side of the pressure plate 31 is coplanar with the inner wall of the left end of the rectangular hole 21. An electric telescopic rod 33 is fixedly installed on the top side of the limiting plate 232. The driving end of the electric telescopic rod 33 is inserted into the corresponding guide groove 32 and fixedly connected to the corresponding end of the pressure plate 31. The push rod of the electric telescopic rod 33 is slidably connected to the corresponding limiting plate 232.

[0033] In this embodiment, after the drive roller 231 presses down on the stacked yellow paper, the electric telescopic rod 33 starts to push the pressure plate 31 towards the stacked yellow paper until the pressure plate 31 presses down on the yellow paper. With the support plate 223 supporting the stacked yellow paper, the yellow paper on one side of the cutter is clamped and limited. With the drive roller 231 and the soft belt 221 clamping and limiting the yellow paper on the other side of the cutter, the yellow paper will not have large wrinkles due to the resistance of the cutter when the cutter cuts the yellow paper, which will affect the cutting process.

[0034] Working principle: When using this improved yellow paper slitting device, the operator first places the stacked yellow paper on the soft belt 221, with the end of the yellow paper positioned below the pressure plate 31. Then, the motor 235 drives the threaded rod 236 to pull the drive roller 231 downward, causing the drive roller 231 to press on the stacked yellow paper. Together with the support plate 223 and the soft belt 221, the yellow paper on the top side of the rectangular hole 21 is clamped and limited. Subsequently, the electric telescopic rod 33 is activated to push the pressure plate 31 downward, which, together with the platform 1, clamps and limits the end of the yellow paper. Then, the operator pushes the platform 1, and the cutter of the cutting device passes through the gap between the soft belt 221 and the inner wall of the rectangular hole 21, thereby cutting off the end of the yellow paper. Then, the electric telescopic rod 33 pulls the pressure plate 31 upward, leaving space for the yellow paper to move.

[0035] It should be noted that during the movement of the pressure plate 31, due to the mutual contact between the pressure plate 31 and the inner wall of the guide groove 32, the pressure plate 31 moves along a linear up-down trajectory.

[0036] After the end of the yellow paper is cut off, the driver 233 drives the drive roller 231 to rotate at a constant speed. At this time, due to the friction between the drive roller 231 and the top yellow paper, the stacked yellow paper moves towards the pressure plate 31, so that the end of the yellow paper passes through the gap between the soft strip 221 and the rectangular hole 21. The moving length of the yellow paper can be controlled according to the number of rotations of the drive roller 231. After the yellow paper of a certain length passes the cutter, the electric telescopic rod 33 is activated and pushes the pressure plate 31 towards the yellow paper to complete the clamping and limiting of the end of the yellow paper. The stacked yellow paper is cut off according to the above. Then the electric telescopic rod 33 pulls the pressure plate 31 upward until the pressure plate 31 and the inner wall of the guide groove 32 abut against each other. At this time, the operator can directly remove the cut yellow paper from the platform 1. Then, the position of the yellow paper can be adjusted according to the above to continuously cut the yellow paper. The above repeated operation can continuously cut off the yellow paper of a certain size from the stacked yellow paper.

[0037] It should be noted that during the sliding process of the soft strip 221, the top of the soft strip 221 remains flat due to the support of the support plate 223 on the soft pad.

[0038] It should be noted that during the movement of the yellow paper, due to the friction between the bottom yellow papers, the soft strip 221 rotates around the round rod 222, thus preventing the stacked yellow papers from becoming misaligned.

[0039] It should be noted that during the cutting of yellow paper, the pressure plate 31, the platform 1, the drive roller 231, and the soft pad clamp and limit the stacked yellow paper, so the contact between the cutter and the yellow paper will not cause wrinkles in the yellow paper.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
