Description

Technical Field

[0001] This utility model relates to the field of blanket processing technology, specifically to a fixed-length cutting device for blanket processing. Background Technology

[0002] As a widely used home textile, blankets require high precision in dimensional accuracy and edge quality during the cutting process in their production and processing. According to CN221778174U, a cutting device based on blanket processing is disclosed. This technology discloses a technical solution including "a base, a mounting frame fixedly installed at the top of the base near the edge, a second electric push rod fixedly installed on the left outer surface of the mounting frame, the telescopic end of the second electric push rod slidingly through the outer surface of the mounting frame and extending to the inner side, a first U-shaped clamping block fixedly installed on the telescopic end of the second electric push rod, and a third electric push rod symmetrically fixedly installed on the inner bottom of the first U-shaped clamping block". It has the technical effect of "by connecting the power supply of the heating wire and conducting its heat energy to the heat-conducting block, by activating the third electric push rod, the heat-conducting block is pushed into the cut of the blanket. Under the action of high temperature, the rough edge of the cut is slightly melted and shrinks, thereby effectively solving the problem of rough edge of the blanket cut, avoiding the problem of the rough edge easily spreading or being damaged, and improving product quality". During the fixed-length cutting process of blankets, due to their soft material and uneven thickness, the traditional pressing method is prone to insufficient compaction in some areas. This uneven compaction can cause local slippage or misalignment of the material at the moment of cutting. At the same time, the soft areas will produce obvious wrinkles and deformations under the action of the blade, ultimately resulting in quality defects such as skewed cut surface, increased fraying, and a serious decrease in fixed-length accuracy.

The lower ends of the upper connecting rod and the upper long connecting rod are pivotally connected to the upper ends of the lower connecting rods on both sides. A shaft frame is fixed to the top of the gantry frame. A second cylinder is pivotally connected to the shaft frame. The output end of the second cylinder is pivotally connected to the upper end of the upper long connecting rod.

[0010] Beneficial effects This invention provides a fixed-length cutting device for blanket processing. Compared with the prior art, it has the following advantages: 1.

The oblique thrust is converted into an amplified, vertically downward huge pressure, which is finally transmitted to the cross plate that is hinged to the lower connecting rods on both sides through the cross rod. Under the precise guidance of the two balance bars, the cross plate moves downward in an absolutely horizontal manner, thereby driving the pressure plate below it to evenly and stably press the blanket. This solves the problem of insufficient local compaction, material slippage or wrinkles during the cutting process that are easily caused by the softness and varying thickness of the blanket material.

[0011] 2. When the handwheel is turned, the threaded rods fixed at its upper and lower ends with opposite thread directions rotate synchronously, driving the positive and negative spiral sleeves to produce linear motions in opposite directions or away from each other. This motion is converted into push-pull control of the effective length of the combination of the telescopic rods and telescopic sleeves on both sides of the front end through the receiving plate and the frame, so that the receiving plate can adjust the overall tilt angle with the pivot point between its rear end and the support rod as the axis. The tilt angle of the receiving plate can be adjusted precisely and conveniently according to the material characteristics of the blanket, the falling trajectory after cutting, and the stacking requirements, so that it always receives the falling blanket in the best welcoming posture, which greatly reduces the impact, bounce and displacement when the material slips.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a fixed-length cutting device for blanket processing, including a body 1, on which a cutting mechanism 2 is provided for cutting blankets, the cutting mechanism 2 including: The main component 21 includes a tray 211 fixed inside the upper part of the machine body 1, and a guide component 212 is provided inside the machine body 1 for guiding the blanket during the conveying process. The pressing assembly 22 includes a gantry frame 221 fixed between the left and right ends of the top of the machine body 1. Balance bars 222 are fixed on the inner walls of both ends of the gantry frame 221. A horizontal plate 223 is slidably installed between the balance bars 222. A pressure plate 224 is provided below the horizontal plate 223. Lower connecting rods 225 are hinged to the left and right sides of the upper end of the horizontal plate 223. A horizontal bar 226 is hinged between the upper ends of the lower connecting rods 225 on both sides. An upper connecting rod 227 and an upper long connecting rod 228 are pivotally connected to the left and right sides of the upper end of the gantry frame 221, respectively. The lower ends of the upper connecting rod 227 and the upper long connecting rod 228 are pivotally connected to the upper ends of the lower connecting rods 225 on both sides, respectively. A shaft frame 229 is fixed on the top of the gantry frame 221. A second cylinder 2210 is pivotally connected to the shaft frame 229, and the output end of the second cylinder 2210 is pivotally connected to the upper end of the upper long connecting rod 228. The material collection component 23 is located at the front of the machine body 1 and is used to collect the cut blankets.

[0016] In this embodiment, the second cylinder 2210 serves as a power source, and its output force acts on the upper end of the upper long connecting rod 228, driving the four-bar linkage consisting of the hinged upper long connecting rod 228, upper connecting rod 227, crossbar 226, and lower connecting rod 225 to move. The oblique thrust is converted into an amplified, vertically downward pressure, which is ultimately transmitted to the cross plate 223 hinged to the lower connecting rods 225 on both sides through the crossbar 226. Under the precise guidance of the two balance bars 222, the cross plate 223 moves downward in an absolutely horizontal manner, thereby driving the pressure plate 224 below it to uniformly and stably press the blanket. This solves the problem of insufficient local compaction, material slippage, or wrinkles during the cutting process that are easily caused by the softness and varying thickness of the blanket material.

[0017] Specifically, the pressing assembly 22 also includes a number of guide rods 2211 arranged in an array on the top of the pressing plate 224, and the guide rods 2211 are slidably installed through the horizontal plate 223. A spring 2212 is sleeved on the outside of the guide rods 2211, and the spring 2212 is located between the horizontal plate 223 and the pressing plate 224.

[0018] In this embodiment, when the pressure plate 224 contacts the blanket surface, if there are uneven thickness or soft protrusions in some parts of the blanket, the pressure plate 224 can overcome the resistance of the spring 2212 and float slightly relative to the horizontal plate 223 along the guide rod 2211, so that the bottom surface of the pressure plate 224 always keeps fully in contact with the blanket surface.

[0019] Specifically, the receiving assembly 23 includes a frame 231 located at the front of the machine body 1. Support rods 232 are fixed on both the left and right sides of the rear end of the top of the frame 231. A receiving plate 233 is provided above the frame 231, and the lower end of the receiving plate 233 is pivotally connected to the upper end of the support rods 232. Telescopic rods 234 are pivotally connected on both the left and right sides of the front end of the top of the frame 231. A telescopic sleeve 235 is slidably installed through the upper end of the telescopic rod 234, and the upper end of the telescopic sleeve 235 is pivotally connected to the lower end of the receiving plate 233. A reverse spiral sleeve 236 is pivotally connected to the middle of the front end of the top of the frame 231, and a positive spiral sleeve 237 is pivotally connected to the middle of the front end of the bottom of the receiving plate 233. A handwheel 238 is provided between the positive spiral sleeve 237 and the reverse spiral sleeve 236, and threaded rods 239 are fixed at both ends of the lower end of the handwheel 238.

[0020] In this embodiment, when the handwheel 238 is turned, the threaded rods 239 fixed at its upper and lower ends with opposite thread directions rotate synchronously, driving the positive spiral sleeve 237 and the negative spiral sleeve 236 to produce linear motions in opposite directions or away from each other. This motion is converted into push-pull control of the effective length of the combination of the telescopic rods 234 and telescopic sleeves 235 on both sides of the front end through the receiving plate 233 and the frame 231, so that the receiving plate 233 can adjust the overall tilt angle with the pivot point of its rear end and the support rod 232 as the axis. The tilt angle of the receiving plate 233 can be adjusted precisely and conveniently according to the material characteristics of the blanket, the falling trajectory after cutting and the stacking requirements, so that it always receives the falling blanket in the best welcoming posture, which greatly reduces the impact, bounce and displacement when the material slips.

[0021] Specifically, the threaded rods 239 at the upper and lower ends of the handwheel 238 have opposite thread directions, and the threaded rods 239 at the upper and lower ends are threadedly connected to the positive screw sleeve 237 and the negative screw sleeve 236, respectively.

[0022] In this embodiment, when the operator turns the handwheel 238, the two threaded rods 239 with opposite directions of rotation rotate synchronously, driving the positive spiral sleeve 237 and the negative spiral sleeve 236 to produce linear displacements in opposite directions.

[0023] Specifically, the main component 21 also includes a support frame 213 fixed to the left and right sides of the front end of the top of the machine body 1. A slide plate 214 is slidably installed on the inner wall of the support frame 213. An upper blade holder 215 is fixed between the two slide plates 214. An upper cutter 216 is installed at the lower end of the upper blade holder 215. A lower cutter 217 is installed between the lower ends of the two slide plates 214. A first cylinder 218 is installed at the upper end of the support frame 213 and is used to drive the slide plate 214 to rise and fall.

[0024] In this embodiment, the first cylinder 218 serves as a power source to drive the slide plate 214 to move vertically up and down along the inner wall of the upright frame 213, thereby driving the upper blade holder 215 and the upper cutter 216 fixed between the two slide plates 214 to move down synchronously, forming a precisely coordinated shearing motion with the lower cutter 217 installed at the lower end of the slide plate 214.

[0025] Specifically, the upper connecting rod 227 and the upper long connecting rod 228 are parallel to each other, and the lower connecting rods 225 on both sides are parallel to each other.

[0026] In this embodiment, a parallel four-bar linkage is formed by setting the upper connecting rod 227 and the upper long connecting rod 228 to be parallel to each other, and maintaining a specific geometric relationship between the lower connecting rods 225 on both sides to be parallel to each other.

[0027] The working principle and usage process of this utility model are as follows: First, the blanket roll to be processed enters the machine body 1 under the drive of the conveying system. It is guided by the guide component 212 set inside the machine body 1 and transported flatly to the tray 211 fixed at the upper end of the machine body 1 to complete the precise positioning before cutting. Once the blanket reaches the preset length, the cutting process begins: the second cylinder 2210 of the pressing assembly 22 acts as the power source, and its output force acts on the upper end of the upper long connecting rod 228, driving the parallel four-bar linkage composed of the hinged upper long connecting rod 228, upper connecting rod 227, cross rod 226 and lower connecting rod 225 to move, amplifying the thrust of the cylinder and converting it into a huge vertical downward pressure; this pressure is transmitted to the cross plate 223 through the cross rod 226, and the cross plate 223 moves downward in an absolutely horizontal manner under the precise guidance of the two balance rods 222, driving the pressure plate 224 below it to press down; at this time, if the blanket has uneven thickness, the guide rod 2211 at the top of the pressure plate 224 can overcome the resistance of the external spring 2212 and float slightly relative to the cross plate 223, so that the bottom surface of the pressure plate 224 adaptively fits and presses the blanket tightly, effectively preventing the material from slipping or wrinkling during cutting.

[0028] After the clamping is completed, the first cylinder 218 drives the slide plate 214 to descend vertically along the inner wall of the stand 213, which drives the upper knife holder 215 and the upper cutter 216 installed at its lower end to move synchronously, forming a precise shearing engagement with the lower cutter 217 fixed at the lower end of the slide plate 214, and cleanly and neatly cuts the blanket. After cutting, the pressing assembly 22 and the cutting mechanism reset synchronously. The cut blanket pieces slide forward to the receiving assembly 23 under the push of subsequent materials or their own gravity. The operator can pre-rotate the handwheel 238 according to the characteristics of the blanket, which synchronously drives the positive spiral sleeve 237 and the negative spiral sleeve 236 to generate relative displacement through the oppositely rotating threaded rods 239 at both ends. This pushes and pulls the front telescopic rod 234 and the telescopic sleeve 235 to precisely adjust the tilt angle of the receiving plate 233 with its rear support rod 232 as the axis, so that it receives the blanket pieces in the best posture, greatly reducing impact and bounce, ensuring that the blanket pieces are neatly stacked, and facilitating subsequent collection and transportation.
