Description

Technical Field

[0001] This invention relates to the field of industrial washing equipment, and more specifically to a device for flipping filter cloth in a vacuum box of a cloth spreading machine. Background Technology

[0002] Some fabric spreading machines on the market lack a filter cloth function on the back half of the duvet cover, while others have a very poor filter cloth function. This is mainly due to insufficient airflow and unreasonable airflow design. When processing duvet covers, the back half is very prone to developing diagonal lines and air bubbles (duvet covers are double-sided). As a result, before the duvet cover enters the ironing machine, the double layers of the back half are misaligned and uneven. Ultimately, the duvet cover comes out of the ironing machine very uneven, with many diagonal lines. A duvet cover should be flattened from beginning to end and fed into the ironing machine. Only after ironing will a very flat, dry duvet cover be obtained. This is the quality goal pursued by linen washing manufacturers and one of the strong competitive advantages of fabric spreading machines. Summary of the Invention

[0003] The purpose of this invention is to provide a device for a flap filter cloth in a vacuum box of a fabric spreading machine. It is installed in the vacuum box into which the linens enter. When the quilt cover enters the vacuum box, the flap of the filter cloth device will fall down and tilt. Air enters through the opening behind the flap base. At the same time, there is a guide plate behind the flap base, which can accurately position the air direction, so that the double-layered quilt cover in the second half can be fully shaken and the air bubbles trapped in the double layers can be expelled. The result is that the double layers of the second half of the quilt cover will be evenly and flatly attached together.

[0004] The technical solution of the present invention is: a device for flipping filter cloth in a vacuum box of a cloth spreading machine, which is set at the cloth spreading entrance at the top of the vacuum box. A winding roller is set at the top of one side of the cloth spreading entrance, and a reflective photoelectric sensor is set at a lower position on the other side. The flipping filter cloth device is set above the reflective photoelectric sensor on the other side of the cloth spreading entrance, and the height of the flipping filter cloth device is lower than the height of the winding roller.

[0005] The flip-plate filter cloth device includes a flip plate, a flip plate seat, and a flip plate seat rotation and fixing mechanism. The flip plate is fixed to the head side of the flip plate seat, and the tail side of the flip plate seat is connected to the flip plate seat rotation and fixing mechanism. The flip plate seat rotation and fixing mechanism can drive the flip plate and the flip plate seat to rotate and retract to a vertical state or rotate and open to an inclined upward state with the tail side of the flip plate seat as the central axis.

[0006] The flip-top seat is provided with guide plate A and guide plate B on its back. Ventilation holes are opened on the flip-top seat between guide plate A and guide plate B. When the flip-top is rotated open to the tilted upward state, the air on the flip-top can enter the vacuum box from the ventilation holes along the guiding direction of guide plate A and guide plate B, and finally form a directional airflow to wash over the linens entering the vacuum box.

[0007] Furthermore, when the flap is rotated open to the tilted upward state, the angle between the tilted surface of the flap and the horizontal plane is 20° to 70°.

[0008] Furthermore, the flip-plate seat rotation fixing mechanism includes two sets of drive mechanisms, which are respectively disposed at both ends of the tail side of the flip-plate seat. Each set of drive mechanisms includes a bearing seat, a cylinder drive bracket, a drive cylinder, and a cylinder fixing seat. The two ends of the tail side of the flip-plate seat pass through the left and right bearing seats respectively and are fixedly connected to the two cylinder drive brackets one-to-one, and can rotate with the cylinder drive brackets. The two cylinder drive brackets are rotatably connected to the telescopic shaft ends of the two drive cylinders one-to-one, and the tail ends of the two drive cylinders are fixed to the two cylinder fixing seats one-to-one. Through the synchronous telescopic movement of the two drive cylinders, the rotational movement of the two cylinder drive brackets is driven, thereby driving the flip-plate seat to rotate.

[0009] The beneficial effects of this invention are: it provides a device for a flap filter cloth in a vacuum box of a fabric spreading machine, which is installed in the vacuum box into which the linens enter. When the quilt cover enters the vacuum box, the flap of the filter cloth device will fall down and tilt. Air enters through the opening behind the flap seat. At the same time, there is a guide plate behind the flap seat, which can accurately position the air direction, so that the double-layered quilt cover in the second half can be fully shaken and the air bubbles trapped in the double layers can be discharged. The result is that the double layers of the second half of the quilt cover will be evenly and flatly attached together.

[0010] Key technological innovations: 1. The flap of this filter cloth device is tilted when it falls to filter the cloth, unlike other manufacturers where the flap falls flat; 2. There is a guide plate at the air inlet on the back of the flap seat, which can precisely control the most effective airflow direction for the filter cloth, unlike other manufacturers.

[0011] The key technical points of the vacuum box flip filter cloth device are: the filter cloth flip plate is tilted so that the precisely directional air can fully shake the back half of the quilt cover, expelling the air bubbles trapped in both sides of the quilt cover, so that the two sides of the quilt cover are neatly overlapped.

Detailed Implementation

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] The function of the fabric spreading machine is to allow the manual hanging of two corners of the washed linen (sheet or duvet cover) on the fabric feeding clamp, and then the fabric spreading machine flattens the linen and sends the flat linen to the ironing machine for ironing.

[0025] Functional demonstration of the flip-plate filter cloth device 6: The prerequisite is that the quilt cover has been wound into the vacuum box 5 by the roller 3 (driven inward rotation by a motor) and the vacuum box 5 (air exhaust by the fan 8, creating negative pressure inside the box, which sucks the linen in). Simultaneously, the head of the quilt cover 2 is already attached to the conveyor belt 7. Figure 1 , 2 As shown. Before the cover 2 enters the vacuum chamber 5, the flip-plate filter cloth device 6 is in a retracted state (cylinder driven, a pair symmetrically arranged on the left and right). After the cover 2 enters the vacuum chamber 5, the flip-plate filter cloth device 6 will tilt forward and extend (cylinder driven), as shown. Figure 3 , 4As shown, from this moment on, the bottom air damper opens, the fan 8 exhausts air outward, negative pressure is generated in the vacuum box 5, and the air on the flip plate 9 is guided by the air guide plate A11 and the air guide plate B12 and then rapidly enters the vacuum box 5 through the opening on the flip plate seat 10. Finally, a directional airflow is formed to wash the duvet cover 2. The rear half of the duvet cover 2 will produce a fine shaking motion (the effect achieved: the rear half of the duvet cover 2 will be washed very flat by the airflow, and the air trapped in both sides of the duvet cover 2 will also be sucked out, so that the two sides of the rear half of the duvet cover 2 will be evenly and flatly attached together). During this process, the conveyor belt 7 will carry the duvet cover 2 backward. When the tail of the duvet cover 2 just passes the reflective photoelectric sensor 4, the bottom air damper in the vacuum box 5 will close, stop the air suction, and the flip plate filter cloth device 6 will retract again. At this time, one flip plate filter cloth action cycle is completed.

[0026] In completing the above action cycle, a relatively important structure is the flap filter cloth device 6 (a pair symmetrically placed on the left and right sides), such as... Figure 6 , 7 As shown in Figures 8, 9, and 10, this is the core content of this application. The basic components of the device are: a flap 9, a flap seat 10, an air guide plate A11, an air guide plate B12, a drive cylinder 13, a bearing seat 14, a cylinder drive bracket 15, and a cylinder fixing seat 16. The specific structure is as follows: The flap filter cloth device 6 includes a flap 9, a flap seat 10, and a flap seat rotation and fixing mechanism. The flap 9 is fixed to the head side of the flap seat 10, and the tail side of the flap seat 10 is connected to the flap seat rotation and fixing mechanism. The flap seat rotation and fixing mechanism can drive the flap 9 and the flap seat 10 to rotate and retract to a vertical state or rotate and open to an inclined upward state with the tail side of the flap seat 10 as the central axis. The flip-up base 10 has guide plates A11 and B12 on its back. Ventilation holes 17 are opened on the flip-up base 10 between guide plates A11 and B12. When the flip-up base 9 is rotated open to an upward tilting position, air above the flip-up base 9 can enter the vacuum chamber 5 through the ventilation holes 17 along the flow direction of guide plates A11 and B12, ultimately forming a directional airflow that washes over the linens entering the vacuum chamber 5. The flip-up base rotation and fixing mechanism includes two sets of drive mechanisms, which are respectively located at both ends of the tail side of the flip-up base 10. Each drive mechanism includes a bearing seat 14, a cylinder drive bracket 15, a drive cylinder 13, and a cylinder fixing seat 16. The two ends of the tail side of the flip-up base 10 pass through the left and right bearing seats 14 respectively and are fixedly connected to the two cylinder drive brackets 15 one-to-one, and can rotate with the cylinder drive brackets 15. Two cylinder drive brackets 15 are rotatably connected to the telescopic shaft ends of two drive cylinders 13, and the tail ends of the two drive cylinders 13 are fixed to two cylinder mounting seats 16. The synchronous telescopic movement of the two drive cylinders 13 drives the rotation of the two cylinder drive brackets 15, which in turn drives the flip plate seat 10 to rotate.

[0027] The core content to be protected in this application is: When the flip-plate filter cloth device 6 is working, the flip plate 9 filters the cloth in an inclined posture (non-horizontal posture), and the angle between its inclined surface and the horizontal plane is in the range of 20° to 70°.

[0028] The core content to be protected in this application 2: When the flap filter cloth device 6 is working, the air on the flap 9 passes rapidly through the opening on the flap seat 10 and is guided by the air guide plate A11 and the air guide plate B12 into the vacuum box 5.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
