Description

Technical Field

[0001] The utility model relates to the field of cord fabric cutting, and particularly to a cord fabric cutting device. Background Art

[0002] After the large roll of calendered cord fabric is unrolled by a cord fabric cutting machine, it is cut by a cutting main machine according to a specific process width and angle, then the cut cord fabric is spliced into a continuous cord fabric by a splicing machine, and finally the continuous cord fabric is wound onto a specific tooling by a coiling device for use in subsequent manufacturing processes. The structural layout of the cord fabric cutting machine is mainly composed of processes such as cord fabric unrolling, cord fabric cutting, cord fabric splicing, rubber strip laminating, and cord fabric coiling. Usually, the cord fabric cutting process mainly includes manual cutting, active diamond knife cutting, and passive disc knife cutting. Among them, for manual cutting, mainly the operator cuts the cord fabric by using a "heating knife" or "tearing by hand". In this cutting method, the working intensity is relatively large during the cutting process, and the cutting effect cannot be guaranteed. When the width of the cord fabric is relatively large, the manual operation is difficult; for active diamond knife cutting, mainly the driving motor drives the diamond knife to rotate, and the active diamond knife is equipped with a lower knife plate. When cutting the cord fabric, the lower knife plate is inserted under the cord fabric, and the motor drives the diamond knife to rotate and move along a specific driving guide mechanism to cut a cord fabric with a certain width. In this cutting method, the probability of cutting the cord fabric cords during the cutting process is relatively large, and the lower knife plate of the active diamond knife may not be inserted under the cord fabric, thus unable to cut the cord fabric, affecting the effective cutting times; for passive disc knife cutting, mainly the passive disc knife and the lower knife plate are pressed and rolled to cut the cord fabric. This cutting method requires a special lower knife plate. During the conveying process of the cord fabric, the lower knife plate is prone to squeezing materials, and it is difficult to handle abnormalities. Moreover, the pressing and rolling cutting process is uncontrollable, affecting the effective cutting times. Content of the Utility Model

When the cutting mechanism swings, it drives the cutting knife to move between an avoidance state of avoiding the cord fabric conveying and a cutting state of cutting the cord fabric. When the cutting knife is in the cutting state, it can move along a second direction forming an angle with the first direction to cut the cord fabric.

[0005] Furthermore, the curtain cutting device also includes a roller mechanism, which is rotatably connected to the machine body.

[0006] Furthermore, the roller mechanism comprises a rotatable movable roller. When the roller mechanism is located at the supporting position, the curtain cutting position is located on a side of the movable roller close to the starting end of the curtain conveying.

[0007] Furthermore, the cutting mechanism also includes a fixed roller, and the movable roller is located on the swing path of the fixed roller.

When the cutter is in the avoidance state, the fixed roller and the cutter are located on the same side of the symmetry plane.

[0009] Furthermore, the roller mechanism also includes: a roller driving member and a roller frame, the roller frame is drivingly connected to the roller driving member and rotatably connected to the machine body, the movable roller is rotatably connected to the roller frame, and the movable roller is arranged in parallel and spaced apart from the rotation axis of the roller frame relative to the rotation axis of the roller frame relative to the machine body.

[0011] Furthermore, the cutting mechanism also includes: a first adjustment bracket, a lifting drive member and a second adjustment bracket, the first adjustment bracket is connected to the main frame, and the first adjustment bracket can be adjusted in the longitudinal and transverse directions relative to the main frame; the lifting drive member is connected to the first adjustment bracket; the second adjustment bracket is driven and connected to the output end of the lifting drive member, the lifting drive member drives the second adjustment bracket to move up and down relative to the first adjustment bracket, and the cutting knife is connected to the second adjustment bracket and moves synchronously with the second adjustment bracket.

[0012] Furthermore, the cutting mechanism also includes a heating component, which is connected to the second adjustment bracket, and the cutting knife is connected to the second adjustment bracket through the heating component.

[0013] Furthermore, there are multiple cutting knives, which are arranged transversely on the main frame, and during cutting, the movement directions of two adjacent cutting knives are opposite to each other.

[0014] Applying the technical solution of the present utility model, by arranging the cutting mechanism to be rotatably arranged relative to the frame body, when the cutting mechanism swings, the cutting knife is driven to move between the avoiding state of avoiding the conveying of the cord fabric and the cutting state of cutting the cord fabric, so as to realize the automatic cutting of the cord fabric by the cutting knife, improve the cutting quality of the cord fabric.

Detailed implementation manners

[0028] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0030] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present utility model.

[0031] In order to solve the problem of poor cutting quality of cord fabric in the prior art, the present utility model provides a cord fabric cutting device and a cord fabric cutting method.

[0032] As Figures 1 to 10 shown, a cord fabric cutting device includes: a machine body 10, a conveying mechanism 20 and a cutting mechanism 30. The conveying mechanism 20 is movably connected to the machine body 10 and conveys the cord fabric along a first direction; the cutting mechanism 30 is located above the conveying mechanism 20 and is rotatably arranged relative to the machine body 10. The cutting mechanism 30 includes a cutting knife 34. When the cutting mechanism 30 swings, it drives the cutting knife 34 to move between an avoidance state of avoiding the cord fabric conveying and a cutting state of cutting the cord fabric. When the cutting knife 34 is in the cutting state, it can move along a second direction forming an angle with the first direction to cut the cord fabric.

[0033] In this embodiment, by arranging the cutting mechanism 30 to be rotatably arranged relative to the machine body 10, when the cutting mechanism 30 swings, the cutting knife 34 moves between the avoidance state of avoiding the conveying of the curtain cloth and the cutting state of cutting the curtain cloth, so as to realize the automatic cutting of the curtain cloth by the cutting knife 34 and improve the cutting quality of the curtain cloth. Specifically, when the conveying mechanism 20 conveys the curtain cloth, the cutting knife 34 is in the avoidance state of avoiding the curtain cloth. When the conveying mechanism 20 conveys the curtain cloth to a predetermined position and stops conveying, the cutting mechanism 30 drives the cutting knife 34 to swing to the cutting state, and the cutting knife 34 cuts the curtain cloth in a second direction forming an angle with the conveying direction. In this way, the automatic conveying of the curtain cloth and the automatic cutting of the curtain cloth are realized simultaneously, and the two do not interfere with each other, so as to effectively realize the automatic cutting of the curtain cloth, improve the cutting quality of the curtain cloth, and at the same time avoid problems such as easy cutting of the connection line, squeezing of the curtain cloth during conveying, and instability during the cutting process, and reduce the working intensity and improve the cutting efficiency.

[0034] It should be noted that the conveying device of this embodiment includes a conveyor belt device, a conveyor belt driving roller 21, a conveyor belt driven roller, a conveyor belt transition roller and a conveyor belt driving motor. The conveyor belt driving motor drives the conveyor belt driving roller 21 to rotate and drives the conveyor belt driven roller and the conveyor belt transition roller to rotate, so as to realize the conveying action of the conveyor belt and meet the conveying requirements of the curtain cloth.

[0035] In this embodiment, the curtain cloth cutting device further includes a supporting roller mechanism 40. The supporting roller mechanism 40 is rotatably connected to the machine body 10. The supporting roller mechanism 40 has a supporting position of swinging upward to support the curtain cloth and a retracted position of swinging downward to avoid the conveying of the curtain cloth. When the cutting knife 34 is in the cutting state, the supporting roller mechanism 40 is located at the supporting position. Specifically, the supporting roller mechanism 40 is located at the bottom of the machine body 10, and the cutting mechanism 30 is located above the frame. When the conveying mechanism 20 conveys the curtain cloth to a predetermined position and stops conveying, the supporting roller mechanism 40 swings upward to the supporting position, and the cutting structure swings downward to the cutting knife 34 in the cutting state. In this way, the curtain cloth is located between the supporting roller mechanism 40 and the cutting mechanism 30. The supporting roller mechanism 40 and the cutting mechanism 30 cooperate to fix the position of the curtain cloth, so as to facilitate the cutting knife 34 to cut the curtain cloth and ensure the length of the curtain cloth to be cut at the same time. When the conveying mechanism 20 conveys the curtain cloth, the supporting roller mechanism 40 is located at the retracted position and the cutting knife 34 is in the avoidance state to avoid the conveying of the curtain cloth.

[0036] In this embodiment, the idler mechanism 40 includes a rotatable movable roller 41. In this way, on the one hand, the movable roller 41 can rotate around its own axis, so that when the movable roller 41 supports the cord fabric, the cord fabric can move along the surface of the movable roller 41, thereby adjusting the tension state of the cord fabric. When the movable roller 41 rotates towards the starting end of the cord fabric conveyance direction, the cord fabric retreats; when the movable roller 41 rotates away from the starting end of the cord fabric conveyance direction, the cord fabric is conveyed forward. On the other hand, the movable roller 41 can swing with the idler mechanism 40 to switch between the support position and the retracted position. When the idler mechanism 40 is in the support position, the cutting position of the cord fabric is on the side of the movable roller 41 close to the starting end of the cord fabric conveyance. That is to say, when the idler mechanism 40 and the cutting mechanism 30 cooperate to fix the position of the cord fabric, the cutting knife 34 is on the side of the movable roller 41 close to the starting end of the cord fabric conveyance. Thus, on one side of the cutting knife 34, the idler mechanism 40 and the cutting mechanism 30 fixedly support the cord fabric, and on the other side, the conveyor belt driving roller 21 supports the cord fabric, which facilitates the cutting of the cord fabric by the cutting knife 34.

[0037] In this embodiment, the cutting mechanism 30 further includes a fixed roller 331. The movable roller 41 is located on the swinging path of the fixed roller 331. When the cutting mechanism 30 swings, the fixed roller 331 abuts against the movable roller 41 and drives the movable roller 41 to rotate in the direction opposite to the first direction to make the cord fabric retreat. The fixed roller 331 and the movable roller 41 in this embodiment are both set to be cylindrical, and their axial directions are both along the horizontal direction and perpendicular to the cord fabric conveyance direction. When the fixed roller 331 and the movable roller 41 abut, the cord fabric is clamped between the two. Specifically, as Figure 3 、 Figure 4As shown, after the conveying mechanism 20 conveys the cord fabric to a predetermined position and stops conveying, the roller mechanism 40 swings upward to the supporting position. The movable roller 41 swings upward along with the roller mechanism 40 and its movement locus is from a position close to the starting end of the cord fabric conveying to a position far from the starting end of the cord fabric conveying. Thus, the movable roller 41 approaches the cord fabric until it contacts and supports the cord fabric. At this time, the movable roller 41 is far from the starting end of the cord fabric conveying relative to the conveyor belt driving roller 21, and the cord fabric between the movable roller 41 and the conveyor belt driving roller 21 is in a tensioned state. Then, the cutting mechanism 30 swings downward. When the fixed roller 331 contacts the movable roller 41, the fixed roller 331 continuously approaches the movable roller 41. Driven by the fixed roller 331, the movable roller 41 rotates relative to its own axis and drives the cord fabric on its surface to move in the direction close to the starting end of the cord fabric conveying, so that the cord fabric between the movable roller 41 and the conveyor belt driving roller 21 changes from a tensioned state to a relaxed state. Thus, when the cutting knife 34 cuts the cord fabric, during the cutting process, as the cutting knife 34 moves, the connecting line of the cord fabric can be automatically avoided, preventing the cord fabric from being cut when cutting the cord fabric, thereby improving the cutting quality of the cord fabric. After the cord fabric cutting is completed, the roller mechanism 40 switches from the supporting position to the retracted position, the movable roller 41 swings downward, and the fixed roller 331 drops a certain distance along with the movable roller 41, so as to send the cut cord fabric to a specific position, preventing phenomena such as folding and material accumulation during the cutting process, thereby improving the production quality and efficiency of the cord fabric.

[0038] In this embodiment, when the roller mechanism 40 is in the supporting position, the cord fabric contacts the movable roller 41 and forms a contact point. The movable roller 41 has a symmetry plane passing through the contact point and the axis of the movable roller 41. When the cutting knife 34 is in the avoidance state, the fixed roller 331 and the cutting knife 34 are located on the same side of the symmetry plane, that is, during the swinging process of the cutting mechanism 30, the moving directions of the fixed roller 331 and the cutting knife 34 are the same. Relative to the supporting position of the movable roller 41, the swinging ranges of the fixed roller 331 and the cutting knife 34 in this embodiment are located at positions close to the starting end of the cord fabric conveying. When the cutting knife 34 switches from the cutting state to the avoidance state, the cutting mechanism 30 swings upward, and the fixed roller 331 and the cutting knife 34 move to positions close to the starting end of the cord fabric conveying, as Figure 1 、 Figure 2 shown. At this time, the fixed roller 331 and the cutting knife 34 are located above the symmetry plane of the contact point and the axis of the movable roller 41.

[0039] In this embodiment, the idler mechanism 40 further includes: an idler driving member 42 and an idler bracket 43. The idler bracket 43 is drivingly connected to the idler driving member 42 and is rotatably connected to the machine body 10. The movable roller 41 is rotatably connected to the idler bracket 43. Specifically, the idler driving member 42 of this embodiment is disposed on the machine body 10 and drives the idler bracket 43 to drive the movable roller 41 to switch between a support position and a retracted position. One end of the idler bracket 43 is connected to the movable roller 41, and the other end is connected to the idler driving member 42. The rotation axis of the idler bracket 43 relative to the base body is located between the movable roller 41 and the idler driving member 42. The rotation axis of the movable roller 41 relative to the idler bracket 43 is the axis of the movable roller 41 itself. The rotation axis of the idler bracket 43 relative to the machine body 10 extends horizontally and is perpendicular to the conveying direction of the curtain fabric. The rotation axis of the bracket roller relative to the base body is the axis of the conveyor belt driving roller 21 in this embodiment. In this way, the rotation axis of the movable roller 41 relative to the idler bracket 43 and the rotation axis of the idler bracket 43 relative to the machine body 10 are arranged in parallel and at intervals. Optionally, the idler driving member 42 can be set as a cylinder, a motor, etc.

[0040] In this embodiment, the cutting mechanism 30 includes: a main frame body 31, a swing driving member 32 and a sub-frame body 33. The main frame body 31 is rotatably connected to the machine body 10, and the cutting knife 34 is disposed on the main frame body 31 so as to be movable horizontally; as Figure 5 shown, the main frame body 31 is arranged in a gantry shape. A slide rail structure is provided between the main frame body 31 and the cutting knife 34. The slide rail structure extends horizontally perpendicular to the conveying direction of the curtain fabric. A transverse movement driving member, such as a motor, an electric cylinder, etc., is provided at one end of the slide rail structure. The transverse movement driving member drives the cutting knife 34 to move horizontally along the extending direction of the slide rail structure to cut the curtain fabric. As Figure 1 shown, the swing driving member 32 is drivingly connected to the main frame body 31. Optionally, the swing driving member 32 can be set as a cylinder. The swing driving member 32 is connected to the machine body 10 and drives the main frame body 31 to drive the cutting knife 34 to swing. The sub-frame body 33 is connected to the main frame body 31 and swings synchronously under the drive of the main frame body 31. The end of the sub-frame body 33 has a fixed roller 331 for contacting and pressing the upper surface of the curtain fabric. The sub-frame body 33 of this embodiment does not extend along a fixed straight line, but is bent multiple times to form a semi-surrounding structure with an opening downward, that is, facing the conveying mechanism 20 as a whole. The starting end of the sub-frame body 33 is connected to the main frame body 31, and a fixed roller 331 is provided at the end. The cutting knife 34 is disposed inside the semi-surrounding structure, and the direction in which the cutting knife 34 extends out of the opening of the semi-surrounding structure faces the direction of the conveying mechanism 20. In this way, when the swing driving member 32 drives the main frame body 31 to swing, the sub-frame body 33 and the cutting knife 34 approach or move away from the conveying mechanism 20 at the same time to cut or avoid the curtain fabric. As Figure 1 shown, when the cutting knife 34 is in the avoidance state, the swing driving member 32 drives the main frame body 31, the sub-frame body 33 and the cutting knife 34 to move away from the conveying mechanism 20; as Figure 3As shown, the cutting knife 34 is in the cutting state. When the main frame body 31, the auxiliary frame body 33, and the cutting knife 34 are in the avoidance state relative to the cutting knife 34, they are close to the conveying mechanism 20, so that the fixed roller 331 abuts against the movable roller 41, and the cutting knife 34 approaches the cord fabric to cut the cord fabric. Optionally, the auxiliary frame body 33 can be provided with a separate driving member. One end of the driving member is fixed to the main frame body 31 to drive the auxiliary frame body 33 to move relative to the main frame body 31 to separately adjust the position of the auxiliary frame body 33.

[0041] As Figures 6 to 9 As shown, in this embodiment, the cutting mechanism 30 further includes: a first adjustment bracket 35, a lifting driving member 36, and a second adjustment bracket 37. The first adjustment bracket 35 is arranged as an L-shaped plate with a horizontal plane and a vertical plane. One end of it is connected to the slide rail structure through a connecting bracket. The connecting bracket is provided with an adjustment hole penetrating its vertical plane. Using a bolt to pass through the adjustment hole and abut against the vertical plane of the first adjustment bracket 35 can adjust its horizontal distance from the connecting bracket. Similarly, the vertical distance between the first adjustment bracket 35 and the connecting bracket can be adjusted through bolts and bolt holes. In this way, the first adjustment bracket 35 can be adjusted longitudinally and transversely relative to the main frame body 31, so as to adjust the position of the cutting knife 34 relative to the cord fabric. When the cutting knife 34 is in the cutting state, the cutting knife 34 can be located between the movable roller 41 and the conveyor belt driving roller 21 in the horizontal direction, and when the cutting knife 34 extends vertically, it can cut the cord fabric, thereby improving the stability of the cutting quality and avoiding cutting failure caused by the position deviation of the cutting knife 34. The lifting driving member 36 is fixed on the vertical plane of the first adjustment bracket 35 and connected to the first adjustment bracket 35; the second adjustment bracket 37 is also arranged as an L-shaped plate with a horizontal plane and a vertical plane. The horizontal plane of the second adjustment bracket 37 is arranged below the lifting driving member 36 and is drivingly connected to the output end of the lifting driving member 36. The lifting driving member 36 drives the second adjustment bracket 37 to move up and down relative to the first adjustment bracket 35. The cutting knife 34 is connected to the second adjustment bracket 37 and moves synchronously with the second adjustment bracket 37. In this way, the position of the cutting knife 34 is adjusted through the first adjustment bracket 35 to ensure the matching accuracy of the cutting knife 34, and the cutting knife 34 is extended and retracted through the lifting driving member 36 to ensure the stability of the cutting process.

[0042] In this embodiment, the cutting mechanism 30 further includes a heating component 38. The heating component 38 is connected to the second adjustment bracket 37, and the cutting knife 34 is connected to the second adjustment bracket 37 through the heating component 38, so as to meet the temperature requirements for cutting. Specifically, the heating component 38 is arranged at the upper end of the cutting knife 34 and around the cutting knife 34 to increase its heating speed without affecting the lower end of the cutting knife 34 from protruding out to cut the cord fabric. According to different types of cord fabrics to be cut, different cutting temperatures are required. The cutting knife 34 is heated to the required temperature by the heating component 38, and then the cutting knife 34 protrudes and pierces into the cord fabric to achieve the cutting of the cord fabric.

[0043] In this embodiment, there are multiple cutting knives 34. The cutting knives 34 are arranged horizontally on the main frame 31, and during cutting, the moving directions of two adjacent cutting knives 34 are opposite to each other. In this embodiment, two cutting knives 34 are provided, namely cutting knife A and cutting knife B. As Figure 5 shown, the cutting knife A and the cutting knife B are arranged adjacent to each other so that the cutting knife A and the cutting knife B can pierce into the same position of the cord fabric, thereby ensuring the effectiveness of cord fabric cutting. Similarly, the heating component 38, the first adjustment bracket 35, the lifting driving member 36, and the second adjustment bracket 37 that cooperate with the cutting knife 34 are all provided in two. When the cutting knife 34 is in the cutting state, both the cutting knife A and the cutting knife B are located in the middle of the main frame 31. After the cutting knife A and the cutting knife B are driven by the lifting driving member 36 to successively protrude downward and pierce into the cord fabric, the cutting knife A and the cutting knife B move in opposite directions along the main frame 31 to cut the cord fabric.

[0044] This embodiment also provides a cord fabric cutting method. Using the above cord fabric cutting device, the cord fabric cutting method includes: the conveying mechanism 20 conveys the cord fabric along the first direction, and the cutting knife 34 is in the avoidance state. When the conveying mechanism 20 conveys the cord fabric to a predetermined position, the conveying stops; the cutting mechanism 30 swings downward, the cutting knife 34 switches to the cutting state, and the cutting knife 34 moves along the second direction in the horizontal direction to cut the cord fabric.

[0045] In this embodiment, the cord fabric cutting method further includes: when the conveying mechanism 20 conveys the cord fabric, the roller mechanism 40 is in the retracted position; when the cutting mechanism 30 swings downward, the roller mechanism 40 swings upward to the supporting position, and the roller mechanism 40 supports the bottom surface of the cord fabric.

[0046] In this embodiment, the cord fabric cutting method further includes: when the cutting mechanism 30 swings downward and the roller mechanism 40 swings upward, the fixed roller 331 of the cutting mechanism 30 and the movable roller 41 of the roller mechanism 40 clamp the cord fabric up and down. The fixed roller 331 drives the movable roller 41 to rotate in the direction opposite to the first direction and makes the cord fabric retreat, and the cord fabric is in a slack state.

[0047] In this embodiment, the cord fabric cutting method further includes: when the cutting knife 34 cuts the cord fabric, the heating component 38 heats the cutting knife 34 and keeps the temperature of the cutting knife 34 within a predetermined range; the lifting driving member 36 drives the cutting knife 34 to descend, the cutting knife 34 penetrates into the cord fabric, and the cutting knife 34 moves horizontally on the main frame body 31 and cuts the cord fabric.

[0048] In this embodiment, the cord fabric cutting method further includes: after the cord fabric is cut, the movable roller 41 of the roller mechanism 40 swings downward, and the fixed roller 331 of the cutting mechanism 30 follows the movable roller 41 to swing downward, and conveys the tail of the cut cord fabric to a specific position; the cutting mechanism 30 swings upward to reset, driving the cutting knife 34 to switch to the avoidance state.

[0049] In summary, the cord fabric cutting method of this embodiment is specifically as follows: the cord fabric is conveyed by the conveying mechanism 20. At this time, the cutting knife 34 is in the avoidance state, and the roller mechanism 40 is in the retracted position; when the cord fabric needs to be cut, the movable roller 41 swings upward around the center of the conveyor belt driving roller 21 under the drive of the roller driving member 42, and the cord fabric is synchronously lifted by a certain distance. At this time, the cord fabric is in a taut state; the cutting mechanism 30 swings downward under the drive of the swing driving member 32, and the sub-frame body 33 and the cutting knife 34 simultaneously swing down with the main frame body 31; when the fixed roller 331 swings downward and contacts the movable roller 41, the cutting knife 34 does not contact the cord fabric. When the fixed roller 331 contacts the movable roller 41, the movable roller 41 will roll relatively, as Figure 10 shown. At this time, the cord fabric changes from a taut state to a relaxed state; the cutting knife 34 can reach the temperature required for cutting under the action of the heating component 38 and can keep the temperature fluctuating within the allowable range; the two cutting knives 34 respectively fall successively under the action of the lifting driving members 36 drivingly connected thereto and penetrate into the cord fabric in sequence; after both cutting knives 34 penetrate into the cord fabric, they move synchronously under the driving action of the transverse movement driving member at the end of the main frame body 31 to realize the cord fabric cutting action; when the cutting knife 34 performs the automatic cord fabric cutting action, since the cord fabric is in a relaxed state, the cord threads in the cord fabric can be automatically avoided during the cutting process, avoiding cutting the cord threads during cutting; after the cord fabric is cut, the movable roller 41 falls around the center of the conveyor belt driving roller 21 under the drive of the roller driving member 42. During the falling process, the fixed roller 331 will move downward for a certain distance to send the tail of the cord fabric to a specific position, preventing the occurrence of folding and material accumulation during the cutting process; the main frame body 31 is lifted upward under the drive of the swing driving member 32, and the movable roller 41 and the cutting knife 34 simultaneously lift upward with the main frame body 31; the cutting knife 34 moves synchronously under the driving action of the transverse movement driving member at the end of the main frame body 31 and returns to the waiting position to perform the next cutting action; the automatic cord fabric cutting action is completed.

[0050] It should be noted that Figure 10The fixed roller 331 indicated by the upper dashed line is in the avoidance state, and the fixed roller 331 indicated by the lower solid line is in the cutting state. The tightened cord fabric between the movable roller 41 and the conveyor belt driving roller 21 is in the conveying state, and the loose cord fabric is in the cutting state.

[0051] It should be noted that the multiple in the above embodiments refers to at least two.

[0052] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0053] 1. Solved the problem of poor cutting quality of cord fabric in the prior art;

[0054] 2. By arranging the cutting mechanism to be rotatable relative to the machine body, when the cutting mechanism swings, the cutting knife is driven to move between the avoidance state of avoiding the cord fabric conveying and the cutting state of cutting the cord fabric, so as to realize the automatic cutting of the cord fabric by the cutting knife and improve the cutting quality of the cord fabric;

[0055] 3. When the fixed roller contacts the movable roller, the fixed roller continuously approaches the movable roller. Driven by the fixed roller, the movable roller rotates relative to its own axis and drives the cord fabric on its surface to move towards the starting end of the cord fabric conveying. As a result, the cord fabric between the movable roller and the conveyor belt driving roller changes from a tightened state to a loose state. When the cutting knife cuts the cord fabric, during the cutting process, as the cutting knife moves, the connection line of the cord fabric can be automatically avoided, preventing the cutting of the cord threads when cutting the cord fabric, thereby improving the cutting quality of the cord fabric.
