[0025] To describe in detail the technical content, structural features, achieved objectives and effects of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0026] In this application, spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", "side" (e.g., as in "side wall") are used to describe the relationship of one element to another (other) element as shown in the drawings. The spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the drawings. For example, if the device in the drawing is flipped, an element described as "under" or "beneath" another element or feature will then be positioned "above" the other element or feature. Thus, the exemplary term "under" can include both the upper and lower orientations. Additionally, the device can be positioned otherwise (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted.

[0027] Figure 1 The sheet transverse cutting device 100 provided by the present utility model is shown, which can cut a sheet along the width direction of the sheet. Specifically, the sheet transverse cutting device 100 includes a frame 1 providing support, a traction mechanism for pulling the sheet, a pressing mechanism for pressing the sheet, and a transverse cutting mechanism for cutting the sheet along the width direction of the sheet.

[0028] As Figure 1-3 shown, the frame 1 includes feet 11 supported on the ground, a pair of side plates 12 arranged oppositely left and right, and a pair of main plates 13 arranged oppositely front and back. A plurality of bolt holes (not marked in the figure) for passing through anchor bolts are formed in the feet 11 to firmly lock the frame 1 to the ground. The pair of side plates 12 and the pair of main plates 13 are fixedly connected by a plurality of fastening screws and enclose the outer frame of the sheet transverse cutting device 100. Among them, the pair of main plates 13 located on the front and back sides are respectively provided with openings (not marked in the figure) for the sheet to enter and leave the sheet transverse cutting device 100.

[0029] Further, a horizontally extending support plate 14 and a transition roller 15 located upstream of the support plate 14 are further arranged inside the frame 1. The transition roller 15 extends horizontally and is rotatably supported inside the frame 1, and is used to guide the sheet; the support plate 14 is used to carry the sheet, the transverse cutting assembly, and cooperate with the pressing assembly to press the sheet (see details below).

[0030] Continue to refer to Figure 1 With Figure 4, the traction mechanism includes a driving roller 21 that provides the traction force for the movement of the sheet, a liftable driven roller 22, a pair of traction cylinders 23 for lifting the driven roller 22, and a traction motor 24 that is drivingly connected to the driving roller 21. The driving roller 21 extends along the width direction and is rotatably supported on a pair of side plates 12 of the frame 1. The traction motor 24 drives the driving roller 21 to rotate via a first reduction gearbox 25. Among them, the driving roller 21 contacts the sheet from the lower side, and the driven roller 22 has a traction position (such as Figure 4 ) where it contacts the sheet from the upper side to traction the sheet together with the driving roller 21 and a disengaging position located above the traction position to disengage from the sheet.

[0031] The first reduction gearbox 25 includes a box body (not marked in the figure) fixedly installed on the frame 1 and an output shaft (not shown in the figure) rotatably installed on the box body, and its output shaft is drivingly connected to the driving roller 21. The traction motor 24 has a housing (not marked in the figure) fixedly installed on the box body of the first reduction gearbox 25 and a motor shaft (not shown in the figure) rotatably installed on the housing. The motor shaft extends into the interior of the box body of the first reduction gearbox 25 and forms a driving connection with the output shaft. Thus, the traction motor 24 can drive the driving roller 21 to rotate.

[0032] Combined with Figure 6 , the traction mechanism further includes a first slide rail 26 fixedly installed inside the frame 1 and a slider 27 slidably engaged with the first slide rail 26. The first slide rail 26 is configured to extend along the vertical direction. The driven roller 22 extends along the width direction, and its head and tail ends are respectively rotatably connected to the corresponding sliders 27 on both sides. Each traction cylinder 23 includes a cylinder body 231 fixedly installed on the top of the first slide rail 26 and a cylinder shaft 232 that can extend and retract relative to the cylinder body 231. One end of the cylinder shaft 232 away from the cylinder body 231 is fixedly connected to the slider 27 to drive the slider 27 to move up and down. Thus, by the action of a pair of traction cylinders 23, the driven roller 22 can be driven to switch back and forth between the traction position and the disengaging position.

[0033] Continuing to refer to Figure 1 and Figure 4 , the pressing mechanism includes a pair of cross beams 31, a pair of pressing cylinders 32, and a pressing beam 33 adapted to contact the sheet. Each cross beam 31 extends along the width direction, and its head and tail ends are respectively fixedly connected to a pair of side plates 11 of the frame 1. Each pressing cylinder 32 includes a cylinder body 321 fixedly installed on a pair of cross beams 31 and a cylinder shaft 322 that can extend and retract relative to the cylinder body 321. Each cylinder shaft 322 is vertically arranged. The pressing beam 33 extends along the width direction and is fixedly installed on the side of each cylinder shaft 322 away from the cylinder body 321. The pressing beam 33 has a pressing position (such as Figure 4 ) where it contacts and presses the sheet and a standby position (such as Figure 6), whereby a pair of clamping cylinders 32 can be used to drive the clamping beam 33 to move back and forth between the clamping position and the standby position.

[0034] Furthermore, the bottom of the above-mentioned pressing beam 33 is provided with a pair of ribs 34 extending transversely, and the pair of ribs 34 are arranged front and back to form a transverse gap (not marked in the figure), and the gap is vertically aligned with the cutting wheel 43 and the cutting groove (see below) provided on the support plate 14. Therefore, when the sheet is cut, the pressing beam 33 can press the sheet upstream and downstream of the cutting wheel 43 to prevent the sheet from wrinkling due to the change of surface tension. Furthermore, the pair of ribs 34 are made of flexible material.

[0035] Continue reading Figure 1 , Figure 2 and Figure 4 The cross-cutting assembly includes a second slide rail 41 extending laterally, a cross-cutting seat 42 that can slide along the second slide rail 41, a cutting wheel assembly with a cutting wheel 43, a cutting motor 46 for driving the cutting wheel 43 to rotate, and a transverse motor 47 for driving the cross-cutting seat 42 to move.

[0036] The second slide rail 41 is fixedly suspended on the lower side of the support plate 14, and the cross-cutting seat 42 is slidably suspended on the lower side of the second slide rail 41. Specifically, the frame 1 also includes a hanging beam 16 fixedly installed on the lower side of the support plate 14, and a pair of second slide rails 41 are respectively fixedly connected to the bottom of the pair of hanging beams 16. The cross section of each slide rail 41 is an I-shaped (such as Figure 4 ), which has a waist (not marked in the figure) formed by grooves on the outer edges of the front and rear sides, and a pair of claws 421 that can be respectively engaged with the waist are fixedly installed on the cross-cutting seat 42, thereby hanging the cross-cutting seat 42 on a pair of second slide rails 41. In other embodiments, the second slide rails can also be independent of the support plate and fixedly installed inside the frame, and the cross-cutting seat can also be slidably arranged on the upper side of the second slide rail.

[0037] The cutting wheel assembly is rotatably supported on the cross-cutting seat 42. Specifically, the cutting wheel assembly includes a cutting wheel 43 for cutting the sheet material, a rotating shaft 44 and a first transmission head 45, and the cutting wheel 43, the rotating shaft 44 and the first transmission head 45 are fixedly connected in sequence. The cross-cutting seat 42 also includes a vertically protruding support column 422, and the rotating shaft 44 is rotatably supported on the support column 422 via a plurality of rolling bearings (not marked in the figure), and the cutting wheel 43 and the first connecting head 45 are respectively located on the front and rear sides of the support column 422 and exposed to the outside.

[0038] The support plate 14 is provided with a transversely extending cutting groove (not shown in the figure), and a portion of the top of the cutting wheel 43 is exposed to the outside from the cutting groove so as to contact and cut the sheet material.

[0039] The cutting motor 46 is fixedly installed at the bottom of the cross-cutting base 42, and it has a rotatable motor shaft (shown in the figure) and a second connector sleeved on the motor shaft (not marked in the figure). The first and second connectors are drivingly connected via a pair of belts (not shown in the figure). Thus, the cutting motor 46 can drive the cutting wheel 43 to rotate.

[0040] Return to Figure 1 And Figure 2 The cross-cutting mechanism further includes a rotatable pulley 48 installed on the frame 1. The pulley 48 is drivingly connected to the cross-cutting base 42 via a transmission chain. The cross-movement motor 47 is drivingly connected to the pulley 48 and can drive the pulley 48 to rotate. Thus, the cross-movement motor 47 can drive the cross-cutting base 42 to move back and forth.

[0041] Among them, the cross-movement motor is drivingly connected to the pulley 48 via a second reduction gearbox 49. The second reduction gearbox 49 includes a box body fixedly installed on the frame 1 (not marked in the figure) and an output shaft rotatably installed on the box body (not shown in the figure), and its output shaft is drivingly connected to the pulley 48. The cross-movement motor 47 has a casing fixedly installed on the box body of the second reduction gearbox 49 (not marked in the figure) and a motor shaft rotatably installed on the casing (not shown in the figure). The motor shaft extends into the interior of the box body of the second reduction gearbox 49 and forms a driving connection with the output shaft.

[0042] The working principle of the sheet cross-cutting device 100 is described as follows: The internal space of the sheet cross-cutting device 100 is slightly wider than the sheet. When it is not performing cutting operations, the cutting wheel 43 is located on one side of the transverse position of the sheet and does not contact the sheet. When performing cutting operations, a pair of traction cylinders 23 act, and the driven roller 22 is lifted to the disengaged position; a pair of pressing cylinders 32 act, and the pressing beam 33 descends to the pressing position and presses against the sheet; the cutting motor 46 is started and drives the cutting wheel 43 to rotate, and the cross-movement motor 47 is started and drives the cross-cutting base 42 to move horizontally; thereafter, the cutting motor 46 contacts and cuts the sheet, thereby completing the cutting operation.

[0043] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable those familiar with this technology to understand the content of the present application and implement it accordingly, and should not be used to limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
