Description

Technical Field

[0001] The utility model relates to a synthetic leather production technology, in particular to a time-delayed knife-lowering mechanism for a dry-process small-scale trial machine. Background Art

[0002] In the synthetic leather production industry, dry-process pilot machines are essential equipment for colorimetric proofing and play a crucial role in ensuring the delivery of finished samples to customers. Under current technology, workers first apply coating to the paper surface before the paper enters an oven for drying. Uniform coating application is achieved by scraping the paper with a blade. However, current dry-process pilot machines exhibit significant operational deficiencies. Operators must lower the blade using both hands, but the blade pressure roller drops immediately, leaving no buffer time. This leaves the operator with insufficient preparation time before the blade drops, making paper jams a significant risk. Furthermore, the lack of a warning device makes it very easy for auxiliary operators to accidentally press their hands during operation. These issues not only impact production efficiency but also pose a serious threat to operator safety. Therefore, improvements to the blade lowering mechanism of dry-process pilot machines are urgently needed to enhance operational safety and stability. Utility Model Content

[0003] The purpose of the utility model is to provide a delayed blade lowering mechanism for a dry-process small-scale test machine. By adding a delay time relay and a buzzer, the operator will not drop the blade pressure roller immediately after pressing the operating platform with both hands, but will have a certain preparation time under the prompt of the buzzer to explain the above-mentioned problem.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A dry-process pilot machine blade delay lowering mechanism includes a dry-process pilot machine. The dry-process pilot machine is the main component of the entire device, providing basic support for subsequent operations. A small test platform at the front of the dry-process pilot machine is equipped with a plurality of unwinding wheels and a rewinding wheel at the front end for paper rewinding. The pilot platform is the main area for coating operations. The plurality of unwinding wheels is used to unwind paper, while the rewinding wheel is responsible for rewinding the coated paper, ensuring orderly movement of the paper throughout the entire process. A coating blade is located between the plurality of unwinding wheels. The coating blade is a key component in the coating operation. Positioned between the unwinding wheels, it can evenly apply coating to the paper. The coating blade is driven by cylinders mounted on both sides. The cylinders provide power for the movement of the coating blade and are installed on both sides to ensure smooth raising and lowering of the blade. The cylinders are controlled via an operating platform on one side of the dry-process pilot machine. The operating platform is the center for the operator to control the entire equipment. Through it, the cylinder can be precisely controlled to achieve the lifting and lowering operation of the paint cutter head.

[0006] A time delay relay is added to the electrical connection between the cylinder and the operating platform, and buzzers are installed on the left and right ends of the pilot platform. The buzzers are electrically connected to the operating platform. When the operating platform drives the motor, the buzzers are directly activated. The time delay relay activates the cylinder and drives the coating blade after a fixed delay. The time delay relay activates the cylinder after a fixed time after the operating platform activates the motor. This ensures that the coating blade begins to descend for coating only when the paper is in the appropriate position. The buzzer is provided to provide an audible prompt to the operator, letting them know the operating status of the equipment.

[0007] The buzzer activates at a fixed time, which is equivalent to the delay time of the time delay relay. Both the buzzer activation time and the delay time of the time delay relay can be adjusted based on actual conditions. Operators can flexibly adjust the buzzer and delay time according to different coating requirements and paper movement speeds to achieve optimal coating results. The lowest point of the cylinder's descent is where the coating blade contacts the paper on the unwinding wheel. This ensures that the coating blade accurately applies coating to the paper while also preventing damage to the paper caused by the blade descending too low.

[0008] The operating platform requires two hands to lower the paint cutter head. Two-handed operation can improve the safety of operation and avoid accidents caused by misoperation.

[0009] The reel is driven by a motor mounted on its side. This motor reduces speed when lowering the coating blade to improve coating stability. This reduces motor speed, allowing the paper to move more smoothly during coating, thereby improving coating quality and stability.

[0010] The coating blade is a replaceable blade, which can be replaced according to the material to be coated. This design allows the device to adapt to the coating needs of different materials, improving the versatility and practicality of the device.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By adding a time delay relay and buzzer, the operator does not immediately lower the cutter head roller after pressing the operating platform with both hands. Instead, the buzzer prompts the operator to prepare the cutter head roller. This greatly reduces the probability of paper jams and avoids accidents caused by the auxiliary operator's hand pressure, significantly improving operational safety.

[0013] The delayed blade drop design allows the coating to adhere more evenly to the paper. The blade drops at the appropriate time, ensuring that the paper receives the coating in a stable state, avoiding uneven coating caused by the sudden drop of the blade, thereby improving coating quality.

[0014] The coating cutter head is replaceable and can be replaced with different cutter heads according to the material to be coated. This allows the equipment to adapt to the coating needs of a variety of different materials, enhancing the versatility and practicality of the equipment.

[0015] The buzzer start time and delay time of the relay can be adjusted according to actual conditions. This allows operators to flexibly adjust equipment parameters according to different paper characteristics, coating properties and production requirements, facilitating operational adjustments and improving the adaptability of the equipment.

[0016] A motor on the side of the reel reduces speed when lowering the coating blade, improving coating stability. This stable coating process reduces rework caused by uneven coating, thereby improving production efficiency. Furthermore, the intelligent operation design reduces time wasted due to operating errors. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be fully described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 1-2As shown, a dry-process small test machine blade delayed lowering mechanism includes a dry-process small test machine 1, a small test platform 11 at the front end of the dry-process small test machine 1 is provided with an array of unwinding wheels 12 and a winding wheel 13 at the front end thereof to enable paper to be wound, and a coating blade 2 is provided between the array of unwinding wheels 12; it is characterized in that the coating blade 2 is driven by a cylinder 21 installed on both sides thereof, and the cylinder 21 is controlled by an operating platform 3 on one side of the dry-process small test machine 1, and the cylinder 21 is additionally provided with a delay time relay, and a buzzer 4 is respectively installed at the left and right ends of the small test platform 11, and the delay time relay and the buzzer 4 are electrically connected to the control button of the operating platform 3, and the buzzer 4 is directly started when the cylinder is driven by the control button of the operating platform 3, and the cylinder 21 is started after a fixed time delay under the action of the delay time relay to drive the coating blade 2.

[0022] The buzzer 4 is started for a fixed time, which is equal to the delay time of the delay time relay. The buzzer 4 start time and the delay time of the delay time relay are adjusted according to actual conditions.

[0023] The lowest point where the cylinder 21 descends is where the coating cutter head 2 is in contact with the paper on the unwinding wheel 12 .

[0024] The operating platform 3 requires the use of both hands to lower the paint cutter head 2.

[0025] The winding wheel 13 is driven by a motor installed on its side. When the coating cutter head 2 is lowered, the motor reduces the speed of the motor to improve coating stability.

[0026] The coating cutter head 2 is a replaceable cutter head, and different cutter heads can be replaced according to the material to be coated. First, the dry-process pilot machine 1 serves as the main body of the entire device, and a plurality of unwinding wheels 12 and a front-end winding wheel 13 are provided on the pilot platform 11 at its front end. The paper is wound under the action of the unwinding wheel 12 and the winding wheel 13. A coating cutter head 2 is installed between the plurality of unwinding wheels 12, and the coating cutter head 2 is driven by a cylinder 21 installed on both sides thereof. The cylinder 21 is electrically connected to the operating platform 3 on one side of the dry-process pilot machine 1, and a delay time relay is added to this connection. At the same time, buzzers 4 are respectively installed at the left and right ends of the pilot platform 11, and the buzzer 4 is also electrically connected to the operating platform 3.

[0027] When the operator activates the motor via the operating platform 3, the buzzer 4 is activated. At this point, the buzzer 4 begins to sound, alerting the operator that the machine is about to enter the next stage. After a predetermined delay equal to the time delay relay, the time delay relay activates the cylinder 21, driving the coating cutter head 2 downward. The lowest point of the cylinder 21 is where the coating cutter head 2 contacts the paper on the unwinding wheel 12, ensuring even coating.

[0028] During operation, the operating platform 3 requires both hands to lower the coating blade 2, improving operational safety. The reel 13 is driven by a motor mounted on its side. When the coating blade 2 is lowered, the motor slows down to improve coating stability. Furthermore, the coating blade 2 is interchangeable, allowing for different blades to be replaced depending on the material being coated, enhancing the versatility of the device.

[0029] Through a series of designs and operating methods, the delayed blade lowering mechanism of this dry pilot machine achieves a safer, more efficient and precise paper coating operation.
