Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a variable-width track rolling mill. Background Technology

[0002] Leather is an indispensable category of consumer goods, widely used in clothing, footwear, home furnishings, automobiles, public services, and many other fields. Among leather products, cowhide products made from genuine cowhide are popular with consumers due to their superior performance and high-end feel, resulting in a large consumption volume.

[0003] The production of artificial leather involves the manufacture of cowhide base fabric. This cowhide base fabric is formed by wet-laying cowhide fibers into a web and then hydroentangling it.

[0004] Flocking is a method of fixing fiber powder (short fibers obtained by grinding or cutting waste fibers) vertically onto an object or substrate coated with adhesive (such as plastic, wood, rubber, leather, paper, cloth, etc.).

[0005] Flocking is a surface treatment technology that uses an electrostatic field to vertically fix fibers onto the surface of a substrate, which can be cloth or leather. The fibers are vertically fixed to the substrate surface by applying adhesive, and the flocked semi-finished product is rolled by a rolling mill to fix the fibers onto the substrate. Existing rolling mills include a pair of tracks for transporting the flocked semi-finished product, and a pair of rollers that span the tracks to roll the flocked semi-finished product. In the existing case, both the track and rollers are fixed to the frame, resulting in a fixed width between the track and causing the rolling mill to only be able to accommodate semi-finished products with a fixed width. Utility Model Content

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a variable width track rolling mill.

[0007] To achieve the above objectives, the technical solution of this utility model is to design a variable-width track rolling mill, including a frame. Two parallel and detachably mounted tracks are provided on the frame. At least one pair of upper and lower rolls are provided on each track. The upper roll has bearing seat supports on its outer sides at both ends. Each bearing seat support has a mounting groove for mounting a bearing seat. The inner surface of the mounting groove that mates with the bearing seat has a sliding groove, allowing the bearing seat to slide within the sliding groove. A lifting cylinder is provided at the upper end of the bearing seat support, and the piston rod of the lifting cylinder is connected to the bearing seat.

[0008] In a further preferred embodiment, bearing housing supports are respectively provided on the outer sides of the frame at both ends of the lower roll. The bearing housing supports are provided with mounting grooves for mounting bearing housings. The inner side of the mounting groove that mates with the bearing housing is provided with a sliding groove. The bearing housing is slidably mounted in the sliding groove. A lifting cylinder is provided at the upper end of the bearing housing support, and the piston rod of the lifting cylinder is connected to the bearing housing.

[0009] A further preferred technical solution is that the pair of upper rolls and the pair of lower rolls share a pair of bearing housing supports.

[0010] A further preferred technical solution includes a bearing seat bracket on each side of the frame, each bearing seat bracket having an installation groove, the length of which covers the upper and lower positions of the track. Each installation groove also contains a sliding groove. An upper bearing seat is located in the sliding groove above the track. An upper cylinder is mounted on the bearing seat bracket at the upper end of the sliding groove, with its piston rod penetrating the sliding groove and connecting to the upper end of the upper bearing seat. The two ends of the upper roller are respectively mounted on the corresponding upper bearing seat. A lower bearing seat is located in the sliding groove below the track, with a lower cylinder mounted on the bearing seat bracket at the lower end of the sliding groove. The piston rod of the lower cylinder penetrates the sliding groove and connects to the lower end of the lower bearing seat. The two ends of the lower roller are respectively mounted on the corresponding lower bearing seat.

[0011] In a further preferred embodiment, the track is provided with two sets of upper and lower rollers, with one set of upper and lower rollers and another set of upper and lower rollers spaced apart on the track. In a further preferred embodiment, a lifting assembly is provided on the frame below the second guide surface.

[0012] The advantages and beneficial effects of this utility model are as follows: the upper and lower rollers above the track need to be opened from the rolling position in a direction away from the track, which facilitates the adjustment of the track spacing.

[0013] By detachably mounting the rails onto the frame, the distance between the two parallel rails can be adjusted to approximately 1.5 meters or 1.3 meters, thus enabling the rolling mill to be used for products of different sizes and enriching its functionality. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] like Figure 1-3 As shown, in order to enable the rolling mill to adapt to flocked semi-finished products of different widths, a variable width track rolling mill includes two parallel and movable tracks 1. The tracks 1 are detachably mounted on the frame, and the distance between the two tracks 1 can be adjusted on the frame to adapt to flocked semi-finished products of different widths.

[0020] In some embodiments, the distance between the two tracks 1 is fixed at about 1.4 meters, which is only applicable to the production of flocked products of about 1.4 meters in size, making it extremely inconvenient to use. By detachably installing the tracks on the frame, the distance between the two parallel tracks 1 can be adjusted to about 1.5 meters or about 1.3 meters, so that the rolling mill can be used for products of different sizes, making the rolling mill more versatile.

[0021] Since the track 1 is detachably mounted on the frame, the spacing between the two parallel tracks 1 can be adjusted to different widths, not limited to the aforementioned 1.3 meters, 1.4 meters, and 1.5 meters.

[0022] To allow the track 1 to move and adjust the spacing between it and the track 1, the upper roll 9 and the lower roll 10 above the track 1 need to be opened away from the rolling position in a direction away from the track 1. This facilitates the adjustment of the track 1 spacing. Therefore, the upper roll 9 and the lower roll 10 are movable. The two ends of the upper roll 9 are mounted on the bearing seats, and the bearing seats are mounted on the sliding bearing seat brackets. Specifically, bearing seat brackets 3 are respectively provided on the outer side of the frame at both ends of the upper roll 9. The bearing seat brackets 3 are provided with mounting grooves 7 for mounting bearing seats. The inner side of the mounting grooves 7 that mates with the bearing seats is provided with sliding grooves 6. The bearing seats are slidably mounted in the sliding grooves 6. A lifting cylinder is provided at the upper end of the bearing seat brackets 3, and the piston rod of the lifting cylinder is connected to the bearing seats.

[0023] The two ends of the lower roll 10 are also mounted on the bearing housing. The bearing housing slides on the bearing housing bracket 3. The bearing housing bracket 3 is provided with an installation groove 7 for mounting the bearing housing. The inner side of the installation groove 7 that mates with the bearing housing is provided with a sliding groove 6. The bearing housing is slidably mounted in the sliding groove 6. A lifting cylinder is provided at the lower end of the bearing housing bracket 3. The piston rod of the lifting cylinder is connected to the bearing housing.

[0024] For a reasonable rolling mill structure and ease of use, the upper roll 9 and the lower roll 10 share a pair of bearing seat brackets 3. The upper roll 9 is located above the track 1, and the lower roll 10 is located below the track 1. The upper roll 9 is stacked above the lower roll 10. Specifically, a bearing seat bracket 3 is provided on each side of the frame. Each bearing seat bracket 3 has a mounting groove 7, the length of which can cover the vertical position of the track 1. Each mounting groove 7 also has a sliding groove 6. An upper bearing seat 4 is provided in the sliding groove 6 above the track 1. An upper cylinder 2 is provided on the bearing seat bracket 3 at the upper end of the sliding groove 6. The piston rod of the upper cylinder 2 passes through the sliding groove 6 and engages with the upper bearing seat 4. The upper roller 9 is connected to the upper bearing seat 4 on the corresponding side of the upper roller 10. The upper bearing seat 4 can be driven to move up and down by the upper cylinder 2, so that the upper roller 9 can move away from or closer to the track 1. The lower bearing seat 5 is provided in the slide groove 6 below the track 1. The lower cylinder 8 is provided on the bearing seat bracket 3 at the lower end of the slide groove 6. The piston rod of the lower cylinder 8 passes through the slide groove 6 and is connected to the lower end of the lower bearing seat 5. The two ends of the lower roller 8 are respectively installed on the lower bearing seat 5 on the corresponding side of the track 1, so that the lower roller 8 can move away from or closer to the track 1. When the upper roller 9 and the lower roller 10 move away from the track 1, the distance between the two tracks 1 can be adjusted to accommodate different flocking products.

[0025] In some embodiments, the surface material of the upper roller 9 is Teflon, so that when the flocking adhesive is adhered to the surface of the upper roller 9, the upper roller 9 can easily remove the adhesive adhering to the surface of the upper roller 9 because the surface material of the upper roller 9 is Teflon.

[0026] In some embodiments, the surface material of the lower roller 10 is a rubber roller, which makes the surface material of the lower roller 10 relatively soft. When the substrate is uneven, the lower roller 10 can also fit with the substrate and has a certain degree of elasticity to allow elastic deformation.

[0027] In order to improve the rolling effect of the rolling mill, two sets of upper rolls 9 and lower rolls 10 are provided on the track 1. One set of upper rolls 9 and lower rolls 10 and another set of upper rolls 9 and lower rolls 10 are arranged alternately on the track 1.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
