Description

Technical Field

[0001] This utility model belongs to the technical field of cutting beds and relates to a fabric laying machine with a sliding plate assisting in fabric laying. Background Technology

[0002] A fabric spreading machine is a machine that lays fabric in layers on a cutting table for cutting. To assist in the feeding process, some fabric spreading machines are equipped with a slide plate, along which the fabric can fall onto the cutting platform. For example, Chinese invention patent application CN113335992A (publication date: 2021.09.03) discloses a fabric spreading machine, including a slide plate that is inclined for feeding fabric. Each side of the bottom of the slide plate has a hem unfolding device. The machine also includes a rotatable pressure bar and a pressure strip located above the pressure bar. The pressure bar can move towards and away from the hem unfolding device. By moving the pressure bar towards the hem unfolding device, the fabric is brought closer to the hem unfolding device as it slides down the slide plate. The two hem unfolding devices unfold the hems of the fabric sliding down the slide plate, and the pressure strip presses and fixes the fabric to the slide plate.

[0003] However, the existing fabric spreading machine's slide plate is difficult to adjust in angle and cannot adapt to the fabric spreading requirements of different fabrics. Therefore, it is very necessary to design a slide plate angle adjustment mechanism so that the slide plate can be easily adjusted in angle to adapt to the fabric spreading requirements of different fabrics. Utility Model Content

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0006] A fabric laying machine with a sliding plate assisting in fabric laying includes an upper sliding plate and a lower sliding plate that are spliced ​​together to form a telescopic inclined fabric laying plate. The lower end of the upper sliding plate is slidably connected to the upper end of the lower sliding plate. The upper end of the upper sliding plate is hinged to the main machine, and the lower end of the lower sliding plate is hinged to the lifting mechanism of the main machine. The lifting mechanism drives the lower end of the lower sliding plate to move up and down and adjusts the tilt angle of the upper and lower sliding plates.

[0007] In the above-mentioned fabric laying machine with a sliding plate assisting the fabric laying process, sliding seats are provided on both sides of the upper sliding plate, and several rollers are rotatably arranged in the sliding seats. The sliding connection of the lower sliding plate is located below the sliding connection of the upper sliding plate, and the bottom of the lower sliding plate is rolledly connected above the rollers. Preferably, the upper and lower sliding plates are always in a parallel state of contact during the adjustment process.

[0008] In the above-mentioned fabric spreading machine with a sliding plate assisting in fabric spreading, the upper end of the upper sliding plate and the upper and lower ends of the lower sliding plate are respectively provided with rolled edges, and angle irons are fixed to the bottom of both sides of the lower sliding plate. The connection between the lower sliding plate and the roller is an angle iron.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-6 :

[0025] A fabric laying machine with a sliding plate assisting in fabric laying includes an upper sliding plate 1 and a lower sliding plate 2, which are spliced ​​together to form a telescopic inclined fabric laying plate. The lower end of the upper sliding plate 1 is slidably connected to the upper end of the lower sliding plate 2. The upper end of the upper sliding plate 1 is hinged to a main unit 3, and the lower end of the lower sliding plate 2 is hinged to a lifting mechanism of the main unit 3. The lifting mechanism drives the lower end of the lower sliding plate 2 to move up and down and adjusts the tilt angle of the upper sliding plate 1 and the lower sliding plate 2.

[0026] The adjustment method in this embodiment is as follows: When the lifting mechanism drives the lower end of the lower slide plate 2 to move upward, the distance between the hinge points at the upper and lower ends of the lower plate is shortened, and a relative sliding in the retraction direction occurs between the lower slide plate 2 and the upper slide plate 1. At the same time, the hinge points of the lifting mechanisms of the upper slide plate 1 and the main unit 3, and the lower slide plate 2 and the main unit 3 rotate accordingly, thereby reducing the tilt angle of the lower plate with respect to the horizontal plane. When the lifting mechanism drives the lower end of the lower slide plate 2 to move downward, the distance between the hinge points at the upper and lower ends of the lower plate is lengthened, and a relative sliding in the extension direction occurs between the lower slide plate 2 and the upper slide plate 1. At the same time, the hinge points of the lifting mechanisms of the upper slide plate 1 and the main unit 3, and the lower slide plate 2 and the main unit 3 rotate accordingly, thereby increasing the tilt angle of the lower plate with respect to the horizontal plane.

[0027] Comparison Appendix Figure 4 and attached Figure 5The sliding structure between the upper sliding plate 1 and the lower sliding plate 2 includes: sliding seats 4 are provided on both sides of the upper sliding plate 1, and a plurality of rollers 5 are rotatably arranged in the sliding seats 4; the sliding connection of the lower sliding plate 2 is located below the sliding connection of the upper sliding plate 1, and the bottom of the lower sliding plate 2 is rolledly connected above the rollers 5; preferably, the upper sliding plate 1 and the lower sliding plate 2 are always in a parallel state of contact during the adjustment process.

[0028] Furthermore, in order to enhance the support strength of the upper slide plate 1 and the lower slide plate 2, the upper end of the upper slide plate 1 and the upper and lower ends of the lower slide plate 2 are respectively provided with rolled edges 6, and angle irons 7 are fixed to the bottom of both sides of the lower slide plate 2. The connection between the lower slide plate 2 and the roller 5 is an angle iron 7.

[0029] In this embodiment, in order to more accurately adjust the angle of the lower plate, the lifting mechanism includes a left lifting mechanism and a right lifting mechanism arranged on the left and right sides of the main unit 3. The left lifting mechanism and the right lifting mechanism synchronously drive the lower plate 2; preferably, the left lifting mechanism and the right lifting mechanism are symmetrically arranged.

[0030] In this embodiment, the specific structure of the lifting mechanism is as follows: the lifting mechanism includes a chain 8 driven by a power device and a lifting seat 9 fixed on the chain 8. The main unit 3 is provided with a vertical guide rail 10 for the lifting seat 9 to slide. A locking block 11 is provided on the top of the lifting seat 9. A locking claw 13 with an opening slot 12 is provided on the lower slide plate 2. The locking claw 13 is hinged to the locking block 11. Preferably, the left and right lifting seats 9 are connected as one unit by a connecting rod. When the power device drives the chain 8 to move, the lifting seat 9 on the chain 8 will have a vertical displacement along the vertical guide rail 10.

[0031] Furthermore, the chain 8 is engaged with the upper sprocket 14, the lower sprocket 15, the tensioner 16, and the drive wheel 17 for transmission, and the drive wheel 17 is connected to the drive motor for transmission.

[0032] To further ensure the driving synchronization of the left and right lifting mechanisms, the drive wheels 17 of the left and right lifting mechanisms are coaxially arranged and mounted on the left and right sides of the same drive shaft 18. The end of the drive shaft 18 is fitted with a drive wheel 20 that is connected to the drive motor 19. (See attached figure) Figure 6 The drive motor 19 and the drive wheel 20 are connected by a sprocket and chain transmission system. The drive motor 19 drives the drive shaft 18 to rotate through the drive wheel 20. The drive shaft 18 simultaneously drives the two drive wheels 17 to rotate synchronously, thereby causing the chain 8 to move.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
