Description

Technical Field

[0001] The invention relates to the field of nonwoven fabric processing equipment, in particular to a towel compression machine and a compression method thereof. Background Art

[0002] The utility model patent with the authorization announcement number CN2444974Y provides a new type of towel compression machine: "It includes a frame, an intermediate slide, and a hydraulic system, and is characterized by also including an upper mold, which is bolted to the lower center of the intermediate slide, a lower mold, which is supported on the lower bottom plate, a guide rail, which is bolted to the lower bottom plate, a draw plate, which is supported on the lower bottom plate, and casters, which are fixed to the lower mold and the draw plate with nuts." The utility model adopts a combined lower mold, and the two sets of lower molds can be interchangeably operated to achieve the compression molding of towels. However, the utility model has the following defects: 1. The degree of automation is very low. The movement of the hydraulic system, the lower mold and the draw plate, and the demoulding and unloading are all manually operated, which has low work efficiency and great safety risks; 2. The lower mold lacks a positioning device, which is very easy to crush the mold.

[0003] The utility model patent with authorization announcement number CN212555176U provides a towel compression device: "It includes a machine table, a frame, an intermittent rotation mechanism, a rotating part, a compression cylinder group, a cylinder, a lifting plate, and a compression rod group. The intermittent rotation mechanism is fixed inside the machine table, and a rotating part is fixed on the top of the machine table. The rotating part is driven to rotate by the intermittent rotation mechanism. Four groups of compression cylinder groups are distributed at equal intervals along the circumferential direction on the top of the rotating part. Each group of compression cylinder groups includes multiple cylinders. The frame is fixed on the top of the machine table, and the top wall of the frame is fixed with a cylinder. The bottom of the cylinder passes through the top wall of the frame and is fixed with a lifting plate. The bottom of the lifting plate is detachably fixed with a compression rod group. The compression rod group has multiple rod bodies, and the rod bodies cooperate with the cylinder bodies." The towel compression device can compress multiple towels in one compression action, has high compression efficiency, and realizes the transposition action by intermittent rotation instead of sensor induction. However, the utility model still has the following defects: 1. The turntable is suspended on the machine, supported and rotated by only two sliders and a central shaft. When compressing towels, a large pressure of about 60 tons is required to compress them into miniature forms. The turntable is easily crushed and scrapped under the large pressure from above; 2. There is a lack of automatic pushing mechanism, and the compressed towels need to be taken out manually, which seriously affects work efficiency; 3. Only an electric push rod is used to push the limit block to move to the left and against the right side wall of the compression cylinder group for limiting. The positioning and fixing accuracy is not enough.

The push rod 702 pushes the turntable 301 up, and the lower end of the fixed column 706 extends into the second circular hole 705. At this time, the turntable 301 is separated from the table 2, and the motor 305 is started to drive the turntable 301 to rotate. When stamping is required, the lifting cylinder 701 pushes the push rod 702 down, and the turntable 301 descends and fits the table 2 for stamping, thereby better realizing the switching between the rotation of the turntable 301 and the stamping.

The push port 801 passes through the table 2 and is connected to a discharge pipe 802. The discharge pipe 802 passes through one side of the frame 1 and is connected to a collection frame. By arranging the push port 801 vertically below the unloading station D, the push rod 510 can be pressed into the stamping hole 404 to directly push the stamped compressed towel out of the stamping die 4 and enter the push port 801 and the discharge pipe 802 to achieve rapid unloading.

[0057] See also Figure 1 A protective plate 10 is installed above the loading station A, and the protective plate 10 is fixed to the frame 1. The upper end of the fixing column 706 is embedded in the protective plate 10. By setting the protective plate 10, the loading station A is isolated from the stamping station C and the unloading station D, thereby improving the safety of workers when loading.

[0059] S1, towel loading: the worker puts the cut towel fabric to be compressed into the punching hole 404 of the punching die 4 on the loading station A;

[0060] S2, rotation positioning:

[0061] First, the lifting cylinder 701 is started to push the push rod 702 upward, the lower end of the T-shaped shaft 703 enters the first circular hole 704, the push rod 702 pushes the turntable 301 upward, and the lower end of the fixing column 706 extends into the second circular hole 705. At this time, the turntable 301 is separated from the table 2, and the motor 305 is started to drive the turntable 301 to rotate clockwise;

[0062] Next, when the stamping die 4 loaded with towel raw materials rotates to the stamping station C, the die detection rod 601 located between the sensing station B and the stamping station C is aligned with the first sensor 602, and the first sensor 602 transmits the information that the die is in place to the control device 9, and the control device 9 controls the upper push cylinder 701 to push the push rod 702 down, and the turntable 301 is lowered to fit the table 2. At this time, the turntable 301 stops rotating, and then the cylinder 605 is started, the die positioning rod 603 extends out, and the second triangular clamping block 604 is clamped into the triangular clamping groove 402 in the stamping die 4 located on the stamping station C;

[0063] S3, stamping and forming: the hole detection rod 607 is aligned with the second sensor 608, and the second sensor 608 transmits the hole alignment information to the control device 9, and the control device 9 starts the compression cylinder 503 to extend and push the pressing plate 502 to slide down along the sliding rod 501, thereby pushing the pressing rod 506 into the stamping hole 404 in the stamping die 4 to compress the towel into a pancake shape;

[0064] S4, material pushing and collection: after stamping and forming, the mold positioning rod 603 retracts, and the second triangular clamping block 604 disengages from the triangular clamping groove 402. Then, the control device 9 controls the upper cylinder 701 to push the push rod 702 up to push up the turntable 301, and starts the motor 305 to drive the turntable 301 to rotate; when the stamping mold 4 enters the unloading station D, it stops rotating, and the control device 9 starts the compression cylinder 503 to push the pressing plate 502 down along the sliding rod 501, and the push rod 510 is pressed into the stamping hole 404 below it, and the stamped compressed towel is pushed out of the stamping mold 4 and enters the push port 801 and the discharge pipe 802 for rapid material unloading and collection. The turntable 301 continues to rotate and enters the loading station, and the cycle is repeated.

[0065] In the above process, when the pressing plate 502 is pressed down to compress the towel, the push rod 510 is simultaneously pressed into the punching hole 404 below it, and the punching and pushing are performed synchronously.
