Description

Technical Field

[0001] This utility model relates to the field of carpet winding technology, and in particular to a winding device for a carpet printing machine. Background Technology

[0002] In the carpet printing production process, the winding device is the core equipment that ensures continuous production and avoids wrinkles or damage to the carpet after printing. Its core function is to smoothly and orderly wind the carpet onto the winding roller after printing. To ensure that the carpet remains taut throughout the winding process, existing winding devices generally adopt a "guide roller + winding roller" structure. That is, one or two sets of guide rollers guide and adjust the tension of the carpet, so that the carpet is conveyed to the winding roller with stable tension to complete the winding.

[0003] However, existing guide roller designs are not adequately adapted to the characteristics of the molten surface of laser-printed carpets, exhibiting significant technical defects. On the one hand, guide rollers are mostly made of metal, which has high hardness. Although the molten surface of the carpet after laser printing is dry, its structure is still relatively fragile (the thickness of the molten fiber layer is only 5-20μm, and there is no rigid support). When the guide roller comes into contact with the carpet printing surface, the high hardness of the metal roller easily causes physical compression of the molten surface under tension and pressure, leading to fiber breakage or deformation. On the other hand, if the surface of the guide roller is rough or has foreign matter attached, it will further aggravate the damage to the molten surface. Foreign particles will also create concentrated pressure at the contact point, causing dents, scratches, or even directly breaking the surface to expose the underlying fibers, resulting in pattern defects and a significant decrease in gloss. Therefore, this application aims to solve the problem that existing guide rollers are prone to damaging the molten surface of laser-printed carpets due to excessive hardness or roughness, leading to pattern defects and a decrease in gloss. A winding device for carpet printing machines is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing guide roller designs that are not adapted to the characteristics of the molten surface of laser-printed carpets, such as the high hardness of metal materials, which easily compresses the fragile molten layer under tension, leading to fiber breakage and deformation, and the damage caused by surface roughness or foreign matter, resulting in dents, scratches, or even scratches on the surface, causing incomplete patterns and reduced gloss.

[0005] The technical solution of this utility model is as follows: a winding device for a carpet printing machine, including a first guide roller, a second guide roller, a third guide roller and a winding roller are provided at the lower end of the first guide roller, and fixed side plates are provided at both the front and rear ends of the first guide roller. The fixed side plates are respectively connected to the first guide roller, the second guide roller, the third guide roller and the winding roller. A first motor is connected to one end of the winding roller. The device also includes an air inlet pipe, and an electric control valve is connected to the air inlet end of the air inlet pipe. An inflation hole is provided on the outer surface of the inflation tube, and an inflatable air bladder that can expand and contract is connected to the outer surface of the inflation tube. When the inflatable air bladder is inflated to its maximum state, the outer surface of the inflatable air bladder is in contact with the carpet.

[0006] Preferably, a second motor is connected to the fixed side plate, a rotating lead screw is connected to the output shaft of the second motor, a lead screw slider is fitted with the rotating lead screw with clearance, and a connecting frame is connected to the lead screw slider.

[0007] Preferably, a sliding sleeve is slidably connected to the connecting frame, and a laser sensor is connected to the sliding sleeve. The laser sensor is used to acquire carpet deviation data.

[0008] Preferably, a connector is connected to the lower end face of the fixed side plate, and a hydraulic push rod is connected to the connector. Positioning slides are provided on both sides of the fixed side plate. The positioning slides are slidably connected to the fixed side plate, and mounting strips are connected to the positioning slides.

[0009] Preferably, a fixing head is fitted onto the shaft end of the first guide roller, the second guide roller, the third guide roller, and the take-up roller. A connecting shaft is rotatably connected to the fixing head, and a first rotating plate and a second rotating plate are rotatably connected to the connecting shaft.

[0010] Preferably, a connecting strip is connected to the outer surface of the connecting shaft on the fixed head of the take-up roller shaft end, a fixed rod is connected to the connecting strip, a rotating disk is connected to the fixed rod, and a motor is provided on the other side of the rotating disk except for the fixed rod, and the motor is fixedly connected to the fixed side plate.

[0011] Preferably, a first fixed rod frame is connected to the outer surface of the fixed head on the end of the take-up roller shaft, a locking screw is connected to the upper end face of the first fixed rod frame, and a second fixed rod frame is sleeved on the locking screw.

[0012] The beneficial effects of this utility model are: 1. Through the rectangular layout of the first guide roller, the second guide roller, the third guide roller and the take-up roller, the carpet can be smoothly guided and rolled up with the reverse side facing down after the front printing is completed. This arrangement ensures that the carpet always faces outward when it is finally rolled up to the take-up roller, which makes it easier for the staff to carry out subsequent operations and fundamentally eliminates the problem of the guide roller damaging the carpet surface when the front is rolled up. 2. By connecting the inflation tube to an external air source, gas can enter the interior of the expansion airbag through the inflation hole. After inflation, the airbag expands and gently lifts the carpet passing over its surface. Compared with the strict requirements of material tolerance and uniformity of traditional rigid roller structures, the expansion airbag, with its flexible contact characteristics, can adapt to the slight fluctuations in carpet thickness, effectively avoiding damage such as indentations, scratches or stress concentration. In addition, the airbag can provide continuous and stable adhesion, significantly improving common phenomena such as wrinkling, material slippage or loosening during the winding process, thereby achieving a neater and tighter winding effect. 3. When the motor drives the rotating disk to rotate, the fixed rod fixed on the disk rotates accordingly, driving the connecting strip to move together. The rotating connecting strip pushes the fixed head installed at the end of the take-up roller, allowing the shaft end of the take-up roller to slide on the fixed side plate. At the same time, through the linkage between the first and second rotating plates, the first guide roller, the second guide roller, and the third guide roller also undergo corresponding displacements. This synchronous structure allows the entire device to be flexibly adjusted to adapt to the take-up needs of carpets of different specifications. Attached Figure Description

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] refer to Figures 1-5 The structure shown is a winding device for a carpet printing machine, including a first guide roller 104. The lower end of the first guide roller 104 is provided with a second guide roller 105, a third guide roller 106 and a winding roller 107. The front and rear ends of the first guide roller 104 are provided with fixed side plates 101. The fixed side plates 101 are respectively connected to the first guide roller 104, the second guide roller 105, the third guide roller 106 and the winding roller 107. One end of the winding roller 107 is connected to a first motor 109. The device also includes an air inlet pipe 202, and an electric control valve is connected to the air inlet end of the air inlet pipe 202. An inflation hole 201 is provided on the outer surface of the inflation tube 202, and an inflatable air bladder 203 is connected to the outer surface of the inflation tube 202. When the inflatable air bladder 203 is inflated to its maximum state, the outer surface of the inflatable air bladder 203 is in contact with the carpet.

[0017] Ideally, the inflation hole 201 should be round. The inflation tube 202 penetrates the shell wall of the third guide roller 106, and the air outlet end of the inflation tube 202 is connected to the inner cavity of the third guide roller 106. The inflation tube 202 is connected to the expansion air bag 203 through the inflation hole 201. Positioning rings 108 are connected to the outer surfaces of the first guide roller 104, the second guide roller 105 and the winding roller 107. The first guide roller 104, the second guide roller 105, the third guide roller 106, and the take-up roller 107 can be as shown in the attached figure. Figure 1 The rectangular arrangement shown can also be set in other forms, such as arc or triangle. The first motor 109 is generally a stepper motor of model 17HS4401 used in conjunction with it. The rectangular arrangement of the first guide roller 104, the second guide roller 105, the third guide roller 106 and the take-up roller 107 allows the carpet to be guided and rolled up from the reverse side after printing on the front side, and ensures that the carpet wound on the take-up roller 107 is always wound up with the front side facing out, so as to facilitate subsequent operations by the staff. Simultaneously, by connecting the inflation tube 202 to the air source, the air source can fill the interior of the expansion airbag 203 with gas through the inflation tube 202 and the inflation hole 201. This allows the expanded airbag 203 to lift the carpet passing over its surface, which is much more efficient than traditional rigid rollers that require extremely high material tolerance and uniformity. The "soft" nature of the airbag perfectly adapts to slight differences in carpet thickness, avoiding indentations, scratches, or stress concentrations that may occur due to rigid contact. At the same time, by maintaining a constant adhesion force, it can effectively reduce common problems during winding, such as core wrinkling, slippage between rolls, and loosening, resulting in a neater and tighter winding.

[0018] Furthermore, a second motor 206 is connected to the fixed side plate 101, a rotating lead screw 204 is connected to the output shaft of the second motor 206, a lead screw slider 205 is fitted on the rotating lead screw 204 with clearance, and a connecting frame 207 is connected to the lead screw slider 205.

[0019] Among them, the second motor 206 is generally a stepper motor of model 17HS4401 used in conjunction with it; When the output shaft of the second motor 206 rotates, it drives the rotating lead screw 204 to rotate, so that the lead screw slider 205, which is clearance-fitted on the rotating lead screw 204, can move along the rotating lead screw 204 to adjust the position of the sliding sleeve 208.

[0020] Furthermore, a sliding sleeve 208 is slidably connected to the connecting frame 207, and a laser sensor 209 is connected to the sliding sleeve 208. The laser sensor 209 is used to acquire carpet deviation data.

[0021] Furthermore, a connector 210 is connected to the lower end face of the fixed side plate 101, and a hydraulic push rod 211 is connected to the connector 210; Positioning slides 102 are provided on both sides of the fixed side plate 101. The positioning slides 102 are slidably connected to the fixed side plate 101, and mounting strips 103 are connected to the positioning slides 102.

[0022] When the hydraulic push rod 211 extends or retracts, it can drive the connector 210 to move, thereby allowing the fixed side plate 101 connected to the connector 210 to move along the positioning slide 102, so as to adjust the sliding sleeve 208 in the vertical position.

[0023] Furthermore, a fixing head 301 is fitted onto the shaft end of the first guide roller 104, the second guide roller 105, the third guide roller 106 and the take-up roller 107. A connecting shaft 302 is rotatably connected to the fixing head 301, and a first rotating plate 303 and a second rotating plate 304 are rotatably connected to the connecting shaft 302.

[0024] The connecting shaft 302 is provided with a positioning strip 305 on its outer side. The positioning strip 305 is rotatably connected to the fixed side plate 101, and the connecting shaft 302 is slidably connected to the positioning strip 305.

[0025] Furthermore, a connecting bar 306 is connected to the outer surface of the connecting shaft 302 on the fixed head 301 at the shaft end of the take-up roller 107. A fixed rod 307 is connected to the connecting bar 306. A rotating disk 308 is connected to the fixed rod 307. A motor is provided on the other side of the rotating disk 308, except for the side connected to the fixed rod 307, and the motor is fixedly connected to the fixed side plate 101.

[0026] The output shaft of the motor is connected to the rotating disk 308 and is set to be concentric. The motor is generally a stepper motor of model 17HS4401. When the motor drives the rotating disk 308 to rotate, the rotating disk 308 can cause the fixed rod 307 connected to the rotating disk 308 to drive the connecting bar 306 to rotate, so that the rotating connecting bar 306 can push the fixed head 301 located on the take-up roller 107 to move, so that the shaft end of the take-up roller 107 passing through the fixed head 301 can also slide on the fixed side plate 101, and under the action of the first rotating plate 303 and the second rotating plate 304, the first guide roller 104, the second guide roller 105 and the third guide roller 106 move synchronously.

[0027] Furthermore, a first fixed rod frame 401 is connected to the outer surface of the fixed head 301 on the shaft end of the take-up roller 107, a locking screw 403 is connected to the upper end surface of the first fixed rod frame 401, and a second fixed rod frame 402 is sleeved on the locking screw 403.

[0028] The second fixed frame 402 engages with the first fixed frame 401 at the shaft end of the take-up roller 107. When it is necessary to disassemble the take-up roller 107, the take-up roller 107 can be quickly disassembled by disassembling the second fixed frame 402 sleeved on the locking screw 403, so as to take out the carpet after it has been rolled up.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
