Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing machinery, in particular to a velvet grinding machine with uniform velvet. Background Art

[0002] The velvet grinding machine is a key equipment for textile finishing. When used, it grinds a layer of velvet on the smooth and flat surface of the cloth to make the cloth softer.

[0003] Most of the current velvet machines have only one velvet zone, and such velvet machines can only velvet the fabric once, resulting in uneven velvet on the fabric.

[0004] In order to improve the uniformity of cloth frosting, there are also frosting machines with two frosting zones on the market. Such frosting machines are generally like the technical solution described in patent application No. 2018217297502, entitled "A Carbon Frosting Machine". From its attached drawings, it can be seen that the cloth enters from the bottom of each frosting zone for frosting, and is output from the bottom of each frosting zone after frosting. Because when the frosting machine is frosting the cloth with good elasticity, the cloth output from the first frosting zone will be pulled very tight, so that the cloth must be restored before entering the second frosting zone to avoid the stretched cloth directly entering the second frosting zone for frosting and affecting the frosting quality. The stretched fabric needs to walk for a period of time without external force to recover. The more elastic the fabric is, the longer it takes to recover after being stretched. In order to allow the fabric to recover and avoid the fabric from contacting the bottom plate and getting dirty, such a velvet machine should set the input and output ports of the velvet zone at a higher position away from the ground or set the distance between the two velvet zones far enough so that the fabric can recover during the walking process between the two velvet zones. Such a velvet machine with two velvet zones set relatively high or with the distance between the two velvet zones far enough is large in size, inconvenient to carry, high in transportation cost, and occupies a large plant space when in use, increasing the operating cost. In addition, such a velvet machine inputs and outputs fabric from the top, while the fabric input and output ports of the velvet zone are below it. Such a structure makes the fabric travel too long in the velvet machine, and the production efficiency is low. Utility Model Content

[0032] Among the two frosting devices: the frosting device close to the cloth feeding device 2 is called the first frosting device 4, and the frosting device close to the cloth discharging device 3 is called the second frosting device 5; the distance D between the discharge roller 71 of the first frosting device 4 and the feed roller 61 of the second frosting device 5 is 650mm, so as to form a cloth recovery space between the discharge roller 71 of the first frosting device 4 and the feed roller 61 of the second frosting device 5. When in use, by controlling the speed difference between the discharge speed of the first frosting device 4 and the feed speed of the second frosting device 5, the cloth 20 can be formed with a drooping section 201 in the cloth recovery space, so that the cloth 20 output from the first frosting device 4 is completely restored and then enters the second frosting device 5 for frosting, which greatly improves the uniformity of the frosting of the cloth 20 by the frosting machine. Such a design not only reduces the size of the velvet machine, facilitates handling and reduces transportation costs, but also greatly shortens the travel distance of the cloth 20 in the velvet machine. The cloth 20 is less likely to wrinkle during its travel in the velvet machine and has high flatness, thereby improving the velvet quality and production efficiency.

[0033] In order to realize intelligent control, such as Figure 1As shown, the present grinding machine also includes a main control module (the main control module is not shown in the accompanying drawings); the cloth feeding device 2, the cloth discharging device 3 and the grinding drive motors of each grinding device are electrically connected to the main control module; the input transmission mechanism 6 of each grinding device also includes an input drive motor 62 for driving the feeding roller 61 to rotate, the input drive motor 62 is installed on the frame 1 and is electrically connected to the main control module; the output transmission mechanism 7 of each grinding device also includes an output drive motor 72 for driving the discharging roller 71 to rotate, the output drive motor 72 is installed on the frame 1 and electrically connected to the main control module; the front mop roller 831, the middle mop roller 833 and the rear mop roller 835 of each velveting device are each driven to rotate by a mop motor, and each mop motor is installed on the frame 1 and electrically connected to the main control module (the mop motor is not shown in the figure); the front rotating roller 832 and the rear rotating roller 834 of each velveting device are each installed with a tension sensor (the tension sensor is not shown in the figure), and the tension sensors on the front rotating roller 832 and the rear rotating roller 834 are electrically connected to the main control module. When in use, the main control module coordinates the rotation speed of the input drive motor 62, the output drive motor 72 and each mop motor according to the feedback signal of the tension sensor on the front rotating roller 832 and the rear rotating roller 834 of each velveting device, so that the tightness of the cloth 20 and the planetary roller group is kept within a controllable range, so that the planetary roller group of each velveting device has a better velveting effect on the cloth 20.

[0034] In order to prevent the cloth drooping section 201 in the cloth recovery space from floating randomly, Figure 1 As shown, a floating device 9 is also provided between the two velvet devices; the floating device 9 includes a floating shaft 91, two rotating arms 92, a floating roller 93 and a floating rotating motor; both ends of the floating shaft 91 can be rotatably mounted on the frame 1, and the rotating axis of the floating shaft 91 is arranged along the left-right direction; one end of each rotating arm 92 is fixed on the floating shaft 91; the floating roller 93 is rotatably mounted between the other ends of the two rotating arms 92, and the rotating axis of the floating roller 93 is arranged along the left-right direction; the floating rotating motor is installed on the frame 1 (the floating rotating motor is not shown in the figure), and the floating rotating motor is used to drive the floating shaft 91 to rotate, and the floating rotating motor is electrically connected to the main control module. When in use, the main control module can control the floating rotating motor to rotate and adjust the rotating angle of the rotating arm 92, so that after the cloth 20 passes around the floating roller 93, the floating roller 93 only slightly contacts the cloth 20, and the floating roller 93 will not exert a large force on the cloth 20 to affect the recovery of the cloth 20.

[0035] In order to further improve the flatness of the cloth 20 during the sanding process in each sanding device, as Figure 1As shown, the conveying roller group 83 of each grinding device also includes a first spreading roller 836 and a first spreading motor; both ends of the first spreading roller 836 can be rotatably mounted on the frame 1, the rotation axis of the first spreading roller 836 is arranged along the left-right direction, and the first spreading roller 836 is located between the middle mopping roller 833 and the front rotating roller 832; the first spreading motor is mounted on the frame 1, and the first spreading motor is used to drive the first spreading roller 836 to rotate, and the first spreading motor is electrically connected to the main control module (the first spreading motor is not shown in the accompanying drawings).

When in use, the cloth 20 in each sanding device bypasses the front cloth winding roller 837 from the bottom of the front cloth winding roller 837, and then bypasses the front mop roller 831 from the top of the front mop roller 831 to enter the cloth inlet, while the cloth 20 output from the cloth outlet first bypasses the rear mop roller 835 and then bypasses the rear cloth winding roller 838 from the bottom of the rear cloth winding roller 838, so that the contact area between the cloth 20 and the front mop roller 831 and the rear mop roller 835 is larger, making it less likely for the front mop roller 831 and the rear mop roller 835 of each sanding device to slip during the feeding process.
