Description

Technical Field

[0001] The invention relates to the field of rubber product molding, and in particular to a cord cutting device, a molding machine and a cord cutting process. Background Art

[0002] At present, in the field of rubber product molding, for semi-automatic molding machines, the cord is mostly cut by manual length and manual cutting. A heated knife is required during the cutting process. The cutter is easy to hook the cord and cannot be cut. The labor intensity of workers is high and the efficiency is low. For automatic molding machines, the cord is at a certain angle to the conveying direction during the conveying process, which makes the material easy to be stretched, and hot knife cutting is required. The cutter is easy to hook the cord during the cutting process, resulting in cutting piles. At the same time, cutting in the direction parallel to the cord will also lead to long cutting strokes and large space occupied by the cutter assembly.

[0003] It can be seen that the existing cord cutting equipment has the following problems:

[0004] 1. The cutting knife uses a hot roller, which needs to be heated all the time and consumes a lot of energy;

[0005] 2. The cord fabric is easily stretched, and the cutter is easily hooked with the cord, resulting in cutting failure and material piling, and the cutting effect is poor;

[0006] 4. The stroke is long and the cutting components take up a lot of space. Summary of the invention

[0007] The main purpose of the present invention is to provide a cord cutting device, a forming machine and a cord cutting process to solve the problem that the cord cutting equipment in the prior art has a poor cutting effect when cutting cords.

[0008] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, there is provided a cord cutting device, comprising: a conveying device and a cutting device, wherein the cord is located on the conveying device, and the cord direction of the cord is parallel to the conveying direction of the conveying device; the cutting device comprises a laterally movable cutting knife, the cutting knife is movably arranged along an extension direction that is not parallel to the cord to cut the cord, and the cutting knife is a cold knife.

[0009] Furthermore, the cutting device also includes an angle adjustment mechanism, which is connected to the cutting knife and drives the cutting knife to rotate, and the axis of the cutting knife driven by the angle adjustment mechanism to rotate is perpendicular to the conveying surface of the conveying device.

[0010] Furthermore, the curtain cutting device also includes a pressing plate device, which includes a pressing plate that can move up and down. The pressing plate is located above the conveying device and descends to press the curtain when the cutting device is cutting.

[0011] Furthermore, the curtain cutting device also includes a material delivery device, which is located above the conveying device and is movably and rotatably arranged. The material delivery device can grab the cut curtain, rotate it to a predetermined direction and place it in a fitting position.

[0012] Furthermore, the material delivery device includes: a translation mechanism, a suction cup mechanism, and a rotating mechanism. The translation mechanism can move in at least one lateral direction to transport the curtain from the conveying device to the fitting position; the suction cup mechanism is connected to the translation mechanism and moves laterally driven by the translation mechanism. The suction cup mechanism is located above the conveying device and can suck up the cut curtain; the rotating mechanism is connected to the translation mechanism or the suction cup mechanism, and can drive the curtain to rotate to a predetermined angle through the translation mechanism or the suction cup mechanism.

[0013] Furthermore, the conveying device includes a first conveying part and a second conveying part, which can be separately arranged in a butt joint, and the butt joint of the first conveying part and the second conveying part is located below the cutting device. After the curtain is cut, the first conveying part and / or the second conveying part move away from each other.

[0014] Furthermore, the curtain cutting device also includes a feeding device, which is located at the first conveying part or the second conveying part. The feeding device includes a moving mechanism and an adsorption mechanism. The adsorption mechanism is connected to the moving mechanism. The moving mechanism drives the adsorption mechanism to move along the conveying direction of the conveying device to convey the curtain head to be cut subsequently to the cutting position of the cutting device.

[0015] According to another aspect of the present invention, a cord cutting process is provided, comprising: a conveying device conveys the cord and makes the cord direction of the cord parallel to the conveying direction; when the cord is conveyed to the cutting position of the cutting device, the cutting knife of the cutting device moves along an extension direction that is not parallel to the cord and cuts the cord.

[0016] Furthermore, before the cutting knife starts cutting, the angle adjustment mechanism of the cutting device drives the cutting knife to rotate around a rotation axis perpendicular to the conveying surface of the conveying device, and forms a predetermined angle between the cutting trajectory line of the cutting knife and the cord.

[0017] Furthermore, before the cutting knife performs cutting, the pressing plate of the pressing plate device descends to press the curtain fabric tightly against the conveying device.

[0018] Furthermore, after the cutting device cuts the curtain, the suction cup mechanism of the delivery device sucks up the cut curtain, the translation mechanism of the delivery device transports the curtain from the conveying device to the bonding position, and the rotating mechanism of the delivery device drives the curtain to rotate and rotates the curtain to a predetermined angle.

[0019] Furthermore, after the cutting device cuts the curtain fabric, the first conveying portion and the second conveying portion of the conveying device move in opposite directions and convey the two cut curtain fabric portions in opposite directions.

[0020] Furthermore, before the cutting knife starts cutting, the adsorption mechanism of the feeding device adsorbs and lifts the head of the curtain fabric, and the moving mechanism drives the adsorption mechanism to move the head of the curtain fabric to the cutting position, and makes the movement speed of the curtain fabric head match the conveying speed of the conveying device. After the fixed length is completed, the adsorption mechanism falls and releases the head of the curtain fabric to the cutting position.

[0021] By applying the technical solution of the present invention, the curtain is conveyed to the corresponding cutting position by the conveying device, and the cutting device of the curtain cutting device is set at this position. After the curtain with the cord direction parallel to the conveying direction is conveyed to the cutting position, the cutting knife can cut the curtain along the direction not parallel to the cord, so as to cut the curtain. The above-mentioned cutting method adopts the cord angle parallel to the conveying direction, so the curtain is not easy to be stretched. At the same time, the cutting knife can be a cold knife. When cutting, the cutting knife directly cuts the cord, thereby avoiding the problem that the knife is easy to hook with the cord in the traditional cutting process. Moreover, the cold knife cutting does not need heating, has low energy consumption, reduces the cutting knife stroke, and reduces the space occupied by the cutting knife assembly. Overall, it solves the problems of the need for knife heating, knife hooking the cord, easy stretching of the curtain, inability to cut the curtain, and long cutting stroke in the traditional curtain cutting process.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0034] In order to solve the problem that the cutting effect of the cord cutting equipment in the prior art is poor when cutting the cord, the present invention provides a cord cutting device, a forming machine and a cord cutting process. The forming machine has the following cord cutting device.

[0035] like Figures 1 to 6 A curtain cutting device shown includes: a conveying device and a cutting device 10, wherein the curtain 50 is located on the conveying device, and the cord direction of the curtain 50 is parallel to the conveying direction of the conveying device; the cutting device 10 includes a laterally movable cutting knife 11, and the cutting knife 11 is movably arranged along an extension direction that is not parallel to the cord to cut the curtain 50, and the cutting knife 11 is a cold knife.

[0036] In this embodiment, the curtain 50 is transported to the corresponding cutting position by the conveying device, and the cutting device 10 of the curtain cutting device is set at this position. After the curtain 50 with the cord direction parallel to the conveying direction is transported to the cutting position, the cutting knife 11 can cut the curtain 50 along the direction not parallel to the cord, so as to cut the curtain 50. The above-mentioned cutting method adopts the cord angle parallel to the conveying direction, so the curtain 50 is not easy to be stretched. At the same time, the cutting knife 11 can be a cold knife. When cutting, the cutting knife 11 directly cuts the cord, thereby avoiding the problem that the knife is easy to hook with the cord in the traditional cutting process. Moreover, the cold knife cutting does not need heating, has low energy consumption, reduces the cutting knife stroke, and reduces the space occupied by the cutting knife assembly. Overall, it solves the problems of the need for knife heating, knife hooking the cord, easy stretching of the curtain 50, inability to cut the curtain 50, and long cutting stroke in the traditional curtain cutting process.

[0037] like Figures 1 to 4 As shown, in this embodiment, the curtain cutting device also includes an angle adjustment mechanism 12, which includes a rotating bracket in a substantially circular shape and a rotating part rotatable relative to the rotating bracket. The two ends of the rotating part are respectively connected to the two sides of the rotating bracket that are opposite to each other in the circumferential direction, so that the rotating part can rotate around the axial direction of the rotating bracket, and because the rotating bracket is arranged horizontally, the rotation axis of the rotating part is longitudinal, that is, the rotation axis of the rotating part is perpendicular to the conveying surface of the conveying device. The cutting knife 11 is arranged at the bottom of the rotating part, and the rotating part extends along the radial direction of the rotating bracket. The cutting knife 11 can also move along the extension direction of the rotating part to perform cutting. In this way, when the rotating part rotates, the cutting knife 11 can be driven to rotate, so that the axis of rotation of the cutting knife 11 is perpendicular to the conveying surface of the conveying device, and the lateral movement trajectory of the cutting knife 11 after rotation is changed accordingly, so as to achieve a change in the angle formed between the cutting knife 11 and the curtain 50, thereby changing the angle of the curtain 50 obtained by cutting, and thus meeting the processing requirements of the angle of the curtain 50. Of course, the specific structural form of the angle adjustment mechanism 12 is not limited to the above structure of this embodiment, and other structural forms of mechanisms can also be used to achieve the above effect.

[0038] In this embodiment, the curtain cutting device further includes a pressing plate device 20, which includes a bracket, at least one pressing plate that is inserted into the bracket and can move up and down relative to the bracket, and a driving component, wherein the pressing plate is located directly above the conveying device, and the bottom surface of the pressing plate is larger and parallel to the conveying surface of the conveying device. In this way, before the cutting device 10 performs cutting, the pressing plate moves downward under the drive of the driving component, and the pressing plate descends to the bottom surface to contact the curtain 50 on the conveying surface of the conveying device and cooperates with the conveying plane of the conveying device to press the curtain 50 tightly, thereby preventing the curtain 50 from being offset by the cutting knife 11 during the cutting process, and ensuring the stability of the position during the curtain cutting process.

[0039] In this embodiment, the curtain cutting device also includes a material delivery device 30, which is located above the conveying device and is movably and rotatably arranged. The main function of the material delivery device 30 is that after the cutting device 10 cuts the curtain 50 and cuts the curtain into pieces, since the edges of the cut curtain 50 are usually inclined, and the inclined edges cannot meet the bonding requirements during subsequent bonding, the cut curtain 50 is grasped and rotated to a predetermined direction by setting the material delivery device 30, so that the edge of the curtain 50 is flush with the edge of the bonding drum, thereby meeting the bonding requirements. At the same time, the material delivery device 30 can also transport the curtain 50 and place it in the bonding position, thereby realizing the transporting effect on the curtain 50.

[0040] Specifically, if Figure 5 As shown, the material delivery device 30 of this embodiment includes: a translation mechanism 31, a suction cup mechanism 32, and a rotation mechanism 33. The translation mechanism 31 can move in at least one lateral direction, and the material delivery device 30 conveys the curtain 50 from the conveying device to the bonding position through the translation mechanism 31; the suction cup mechanism 32 is connected to the translation mechanism 31, and moves laterally driven by the translation mechanism 31, the suction cup mechanism 32 is located above the conveying device and can suck up the cut curtain 50; the rotation mechanism 33 is connected to the translation mechanism 31 or the suction cup mechanism 32, and can drive the curtain 50 to rotate to a predetermined angle through the translation mechanism 31 or the suction cup mechanism 32, so that the curtain 50 can smoothly complete the subsequent bonding process. During the operation, the suction cup mechanism 32 sucks up the cut curtain 50 located at the predetermined position of the conveying device, and then the translation mechanism 31 operates to convey the curtain 50 from the top of the conveying device to the top of the bonding position, and then the rotating mechanism 33 operates, and the rotating mechanism 33 directly or indirectly drives the curtain 50 to rotate a predetermined angle, so that the edge of the curtain 50 is flush with the edge of the bonding drum, and finally the suction cup mechanism 32 stops the negative pressure and places the curtain 50 at the bonding position, and the conveying mechanism at the bonding position can carry out subsequent transportation. During the above-mentioned operation process, the operation sequence between some mechanisms can be adjusted according to the situation, for example, translation and rotation can be carried out at the same time, or rotation can be carried out first and then translation, etc., as long as the curtain 50 can be finally rotated to the required angle and placed at the bonding position. The translation mechanism 31 can be provided with one or more according to the required translation direction, and the translation of each position can be realized by one translation mechanism 31, or multiple translation mechanisms 31 can be provided, and the translation directions of each translation mechanism 31 are different, so as to cooperate with each other to realize the translation of the curtain 50 at each position. This embodiment adopts the arrangement mode of two translation mechanisms 31 , and the two translation mechanisms 31 both move horizontally and the moving directions are perpendicular to each other.

[0041] In this embodiment, the rotating mechanism 33 and the translating mechanism 31 of the material delivery device 30 can both be servo devices. Figure 6 As shown, during the material delivery process, the curtain 50 is sucked up by the suction cup mechanism 32 at the conveying position a, a translation mechanism 31 delivers the sucked curtain 50 from position a to position c, the rotation mechanism 33 rotates the sucked curtain 50 from position c to position d by a certain angle, and another translation mechanism 31 translates the sucked curtain 50 from position d by a certain distance to the required position b or position e, the suction cup mechanism 32 puts down the curtain 50 at position b or position e, the translation mechanism 31 and the rotation mechanism 33 return to their positions, and the material delivery process ends.

[0042] In this embodiment, the conveying device includes a first conveying part and a second conveying part. The first conveying part and the second conveying part can both adopt strip conveyor belts. The first conveying part and the second conveying part are arranged in the same line, that is, the conveying directions of the two are parallel or coincident. The conveying surfaces of the first conveying part and the second conveying part are on the same horizontal plane and are perpendicular to the plane where the blade surface of the cutting knife 11 is located. The first conveying part and the second conveying part can be arranged separately from each other. There is a separation area between the first conveying part and the second conveying part, and the cutting device 10 is arranged on the separation area between the first conveying part and the second conveying part. During normal conveying, the conveying directions of the first conveying part and the second conveying part are the same. After the cutting device 10 completes cutting, the curtain 50 is cut into two parts and located on the planes of the first conveying part and the second conveying part respectively. At this time, the two parts of the curtain 50 after cutting are generally still in contact with each other or are very close to each other. It is difficult for the subsequent material delivery device 30 or the previous feeding device 40 to operate one of the curtains 50. Therefore, the above-mentioned setting of the first conveying part and the second conveying part is adopted. After cutting, the first conveying part and / or the second conveying part move in a direction away from each other, thereby separating the head and tail parts of the curtain 50, making it easier for the material delivery device 30 and the feeding device 40 to operate the corresponding curtain 50.

[0043] In the present embodiment, the curtain cutting device further comprises a feeding device 40, and the feeding device 40 is located at the first conveying part or the second conveying part, that is, according to the conveying direction, one of the feeding device 40 and the delivery device 30 is located at the first conveying part, and the other is located at the second conveying part, or both the feeding device 40 and the delivery device 30 can be arranged at the same conveying part, and the present embodiment adopts the latter, so that the feeding device 40 realizes the feeding before cutting, and the delivery device 30 realizes the delivery after cutting. The feeding device 40 of the present embodiment comprises a moving mechanism and an adsorption mechanism, and the moving mechanism and the adsorption mechanism are respectively similar to the translation mechanism 31 and the suction cup mechanism 32 of the aforementioned delivery device 30, and the adsorption mechanism is connected to the moving mechanism, and the adsorption mechanism is used to adsorb the curtain 50 that needs to be cut later, and the moving mechanism drives the adsorption mechanism to move along the conveying direction of the conveying device, so as to deliver the curtain 50 that needs to be cut later to the cutting position of the cutting device 10. When in action, the adsorption mechanism moves in the opposite direction of the conveying direction of the curtain 50 and approaches the curtain head 50, and adsorbs the curtain head 50 when it reaches the curtain head 50. Then the moving mechanism drives the adsorption mechanism to move along the conveying direction of the curtain 50, thereby driving the curtain head 50 to the cutting position.

[0044] The cutting device 10 of this embodiment also includes a knife plate, which is located below the cutting knife 11, and the cutting knife 11 and the knife plate are respectively located on the upper and lower sides of the curtain 50, and the knife plate is relatively fixedly arranged to receive the curtain 50, so that the cutting knife 11 can move up and down to approach or move away from the knife plate. When cutting is required, the cutting knife 11 descends, and the blade of the cutting knife 11 cuts the curtain 50 by abutting against the knife plate.

[0045] This embodiment also provides a curtain cutting process, which is performed by the above-mentioned curtain cutting device, and the curtain cutting process includes: the conveying device conveys the curtain 50, and makes the cord direction of the curtain 50 parallel to the conveying direction; when the curtain 50 is conveyed to the cutting position of the cutting device 10, the cutting knife 11 of the cutting device 10 moves along the extension direction that is not parallel to the cord, and cuts the curtain 50. In this way, the above-mentioned curtain cutting device cooperates with the curtain cutting process to achieve the effect of cutting the curtain 50 by a cold knife, and at the same time, when the curtain 50 is cut, the curtain 50 is not easily stretched and is not easily hooked with the cord.

[0046] In this embodiment, before the cutting knife 11 performs cutting, the angle adjustment mechanism 12 of the cutting device 10 drives the cutting knife 11 to rotate around a rotation axis perpendicular to the conveying surface of the conveying device, and forms a predetermined angle between the cutting trajectory of the cutting knife 11 and the cord, so that the angle of the cut cord 50 meets the requirements. The specific angle can be set according to the requirements of the cord cutting angle.

[0047] In this embodiment, before the cutting knife 11 starts cutting, the pressing plate of the pressing plate device 20 descends to press the curtain 50 against the conveying device to stabilize the curtain 50 and avoid accidental shaking of the curtain 50 during cutting. Then the cutting device 10 can adjust the angle for cutting.

[0048] In this embodiment, after the cutting device 10 cuts the curtain 50, the suction cup mechanism 32 of the delivery device 30 sucks and lifts the cut curtain 50, the translation mechanism 31 of the delivery device 30 delivers the curtain 50 from the conveying device to the bonding position, and the rotating mechanism 33 of the delivery device 30 drives the curtain 50 to rotate and rotates the curtain 50 to a predetermined angle.

[0049] In this embodiment, after the cutting device 10 cuts the curtain 50 and before the material delivery device 30 operates, the first conveying part and the second conveying part of the conveying device move in opposite directions and convey the two cut parts of the curtain 50 in opposite directions, and then the material delivery device 30 operates again to realize the conveying and rotation of the curtain 50.

[0050] In this embodiment, before the cutting knife 11 performs cutting, more specifically, before the pressing plate device 20 presses the curtain 50, the adsorption mechanism of the feeding device 40 adsorbs and lifts the head of the curtain 50, and the moving mechanism drives the head of the curtain 50 to move to the cutting position by driving the adsorption mechanism, and makes the movement speed of the head of the curtain 50 match the conveying speed of the conveying device. After the fixed length is completed, the adsorption mechanism falls and releases the head of the curtain 50 to the cutting position, and then the pressing plate device 20 moves again to press the curtain 50, and then cutting is performed.

[0051] The overall process of the curtain cutting process of this embodiment is as follows: the feeding device 40 absorbs and lifts the head of the curtain 50 and delivers it to the cutting position, the pressing plate device 20 operates to press the curtain 50, and then the angle adjustment mechanism 12 of the cutting device 10 drives the cutting knife 11 to rotate to adjust the cutting angle. After the adjustment is completed, the cutting knife 11 moves horizontally to cut the curtain 50, and then the first conveying part and the second conveying part move in opposite directions to separate the two cut parts of the curtain 50, and the front end delivery device 30 operates to absorb, move, rotate and convey the cut curtain 50 to a specific angle and a specific position, and the rear end feeding device 40 absorbs and lifts the head of the curtain 50 again and delivers it to the cutting position for the next cutting, and repeats this process.

[0052] It should be noted that, the multiple in the above embodiments refers to at least two.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0054] 1. Solve the problem that the cord cutting equipment in the prior art has poor cutting effect when cutting cords;

[0055] 2. It adopts cold knife cutting, no need for heating, and low energy consumption;

[0056] 3. The cord direction is parallel to the conveying direction, and the cord is not easily stretched;

[0057] 4. The cutter cuts from one side to cut the cord. The cutting angle can be adjusted to prevent the cutter from hooking with the cord.

[0058] 5. The cutter stroke is shortened and the space occupied by the cutter assembly is reduced.
