Technical Field

[0001] The invention relates to the technical field of edge banding machines, and in particular to a feeding mechanism and an edge banding machine. Background Art

[0002] The feeding mechanism of the bayonet strip is mainly used on the edge banding machine of woodworking machinery. It can send the bayonet strip to a specific position so that the bayonet strip and the main strip after gluing can be neatly bonded together.

[0003] In the related art, the feeding mechanism cannot ensure the accurate feeding position of the bayonet strip, so that the bayonet strip and the main strip cannot be bonded at the same head during the bonding process, which seriously affects the product quality. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of the present invention provides a feeding mechanism.

[0006] A second aspect of the present invention provides an edge banding machine.

[0007] The first aspect of the present invention provides a feeding mechanism, comprising: a material support plate, which is configured to place materials; a limiting device, which is arranged on the material support plate, and the limiting device constructs a limiting outlet; a clamping device, which is arranged on the material support plate, and the clamping device is configured to clamp one of multiple materials; a pushing device, which is arranged on the material support plate, and the pushing device and the clamping device are located on the same side of the limiting outlet, and the pushing device is configured to push the clamping device to move toward the limiting outlet; a feeding device, which is arranged on the material support plate and is located on the other side of the limiting outlet, and the feeding device is configured to transport the material passing through the limiting outlet.

[0008] The feeding mechanism proposed in the present invention includes a material support plate, a limiting device, a clamping device, a pushing device and a feeding device. Among them, the material support plate can be used to place materials; the limiting device is arranged on the material support plate, and a limiting outlet is constructed on the material support plate, and the materials are stored on one side of the limiting outlet; the clamping device is arranged on the material support plate, located on one side of the limiting outlet, and the clamping device can clamp one of multiple materials; the pushing device is arranged on the material support plate, located on one side of the limiting outlet, and the pushing device can push the clamping device to move toward the limiting outlet to drive the material clamped by the clamping device to pass through the limiting outlet; the feeding device is located on the other side of the limiting outlet, and when the material is pushed to the feeding device, the feeding device can continue to transport the material to a specific position; after one action is completed, the above actions are repeated until the entire edge sealing process is completed.

[0009] That is, the feeding mechanism proposed in the present invention can convey one of the multiple materials to a specific position through the coordinated action of multiple devices, while the remaining materials remain on the material pallet. By continuously repeating the above process, the accuracy of the feeding position can be guaranteed, and the feeding position tolerance can be controlled within plus or minus 2 mm.

[0010] Specifically, the feeding mechanism proposed in the present invention is used to convey the bayonet strip, and can convey the bayonet strip to a specific position, so that the bayonet strip and the main strip after gluing are neatly bonded together, solving the problem that the bayonet strip and the main strip of the edge banding machine cannot be bonded uniformly at the head during the bonding process. By using this feeding mechanism to feed the bayonet strip, the bonding size tolerance of the bayonet strip head can be controlled within plus or minus 2 mm.

[0011] The feeding mechanism according to the above technical solution of the present invention may also have the following additional technical features:

[0012] In the above technical solution, the limit device includes: a limit bearing, which is arranged on the material support plate, and a plurality of limit bearings are distributed along a straight line on the material support plate to form a limit end face; an adjustment plate, which is arranged on the material support plate, and a limit outlet is arranged between the adjustment plate and the limit end face; wherein the end of the material clamped by the clamping device is opposite to the position of the limit outlet, and the end of the remaining material is abutted against the adjustment plate.

[0013] In this technical solution, the limit device includes a limit bearing and an adjustment plate. There are multiple limit bearings, which are distributed on the material support plate along a straight line, and form a limit end face at the edge of the material support plate; the adjustment plate is arranged on the side of the limit end face, and is spaced apart from the limit end face to form a limit outlet. In particular, during the operation of the feeding mechanism, the material at the end abuts against the limit end face, and then the material at the end is limited on the side, and the end of the material is opposite to the limit outlet, ensuring that the material can pass through the limit outlet under the action of the clamping device and the pushing device; the end of the remaining material abuts against the adjustment plate, thereby overcoming the friction between adjacent materials and ensuring that the remaining material remains on the material support plate.

[0014] That is, the above limitation can ensure that only one piece of material is pushed at a time, and the above process is repeated continuously to ensure that the pushing process is carried out in an orderly manner. In addition, the adjustment plate and the material support plate are movably connected. Before the feeding mechanism works, the distance between the adjustment plate and the limit end face is adjusted according to the size of the material, so that the size of the limit outlet is about 1mm larger than the material size.

[0015] In any of the above technical solutions, it also includes: a clamping cylinder, the clamping cylinder and the limit bearing are located at opposite ends of the material support plate, and the clamping cylinder is configured to push the material to abut against the limit end surface.

[0016] In this technical solution, the feeding mechanism also includes a clamping cylinder. The clamping cylinder and the limit bearing are located at opposite ends of the material support plate. During the operation of the feeding mechanism, the clamping cylinder works to push the material to the position of the limit bearing, so that the material at the end is against the limit end face, ensuring that the material is relative to the limit outlet, and ensuring that the material can pass through the limit outlet under the action of the clamping device and the pushing device.

[0017] In any of the above technical solutions, the pushing device includes: a linear guide rail, which is arranged on the material support plate and located at the limit outlet, the linear guide rail is arranged along the extension direction of the limit end face, and the clamping device is arranged on the linear guide rail; a pushing cylinder, which is arranged on the material support plate and connected to the clamping device, and the pushing cylinder is configured to push the clamping device to move along the linear guide rail.

[0018] In this technical solution, the pusher device includes a linear guide rail and a pusher cylinder. The linear guide rail is arranged on the material support plate, located at the limit outlet, and is arranged along the extension direction of the limit end face; the pusher cylinder is arranged on the material support plate and connected to the clamping device. The clamping device is arranged on the linear guide rail. During the operation of the feeding mechanism, the clamping device clamps the material at the end, and the pusher cylinder drives the clamping device to move along the linear guide rail, thereby driving the material clamped by the clamping device to pass through the limit outlet, ensuring the orderly feeding.

[0019] In any of the above technical solutions, the feeding device includes: a first feeding motor, connected to the material support plate and located at the limit outlet; a first feeding wheel, arranged on the output shaft of the first feeding motor and capable of rotating under the drive of the first feeding motor; a second feeding motor, connected to the material support plate and located at the limit outlet; a second feeding wheel, arranged on the output shaft of the second feeding motor and capable of rotating under the drive of the second feeding motor; wherein the first feeding wheel and the second feeding wheel have different rotation directions, and the first feeding wheel and the second feeding wheel are respectively located on both sides of the limit outlet.

[0020] In this technical solution, the feeding device includes a first feeding motor, a first feeding wheel, a second feeding motor and a second feeding wheel. The first feeding motor is used in conjunction with the first feeding wheel and can rotate under the drive of the first feeding motor; the second feeding motor is used in conjunction with the second feeding wheel and can rotate under the drive of the second feeding motor; the first feeding wheel and the second feeding wheel are located at the limit outlet and are respectively located on both sides of the limit outlet, and the first feeding wheel and the second feeding wheel have different rotation directions. When the material is pushed into the gap between the first feeding wheel and the second feeding wheel, the two sides of the material are respectively in contact with the first feeding wheel and the second feeding wheel, and then the first feeding wheel and the second feeding wheel jointly drive the material.

[0021] In particular, since the first feeding wheel and the second feeding wheel are closer to the designated position, and the first feeding wheel and the second feeding wheel first contact the head of the material, the feeding stability can be ensured, and the failure during the feeding process can be effectively reduced to avoid position deviation. In addition, in order to ensure the driving force, the end surfaces of the first feeding wheel and the second feeding wheel are provided with wrinkles or tooth structures.

[0022] In any of the above technical solutions, the second feeding motor is movably connected to the material support plate, and the feeding mechanism also includes an adjusting cylinder, which is connected to the second feeding motor and is configured to adjust the distance between the first feeding wheel and the second feeding wheel.

[0023] In this technical solution, the second feeding motor is movably connected to the material support plate, and the feeding mechanism also includes an adjusting cylinder. The adjusting cylinder is connected to the second feeding motor and can adjust the distance between the second feeding wheel and the first feeding wheel. Before the material passes through the limit outlet, the distance between the first feeding wheel and the second feeding wheel is greater than the size of the material, ensuring that the material can smoothly enter between the first feeding wheel and the second feeding wheel; when there is a gap between the first feeding wheel and the second feeding wheel, the adjusting cylinder drives the second feeding wheel to move toward the first feeding wheel, so that the first feeding wheel and the second feeding wheel are in contact with the material at the same time, ensuring the driving force for feeding.

[0024] In any of the above technical solutions, it also includes: a pressure rod, which is arranged on the material support plate, and the pressure rod, the pushing device and the clamping device are located on the same side of the limit outlet.

[0025] In this technical solution, the feeding mechanism also includes a pressure rod. The pressure rod is arranged on the material support plate, and the pressure rod, the material pushing device and the material clamping device are located on the same side of the limit outlet. Specifically, there is a certain distance between the pressure rod and the material support plate to ensure the storage of the material; there is a gap of about 2 mm between the pressure rod and the upper surface of the material to ensure the upper limit of the material while ensuring the mobility of the material.

[0026] Specifically, the distance between the pressure rod and the material support plate is adjustable to accommodate materials of different sizes.

[0027] A second aspect of the present invention provides an edge banding machine, comprising: a main machine, the main machine is configured to convey a main strip; a feeding mechanism as in any one of the above technical solutions, arranged on the main machine, the feeding mechanism is configured to drive the material to contact the main strip.

[0028] The edge banding machine proposed by the present invention comprises a main machine and a feeding mechanism as in any of the above technical solutions. Therefore, all the beneficial effects of the above feeding mechanism are not discussed here one by one.

[0029] Among them, the main machine can convey the main strip, the feeding mechanism is arranged on the main machine, and the conveying direction of the material is different from the conveying direction of the main strip. The feeding mechanism conveys the material according to the position of the main strip to ensure that the material and the main strip after glue coating are neatly bonded together, thereby solving the problem that the head of the edge banding machine material and the main strip cannot be bonded consistently during the bonding process.

[0030] The edge banding machine according to the above technical solution of the present invention may also have the following additional technical features:

[0031] The above technical solution also includes: a lifting seat, and the feeding mechanism is arranged on the main machine through the lifting seat.

[0032] In this technical solution, the edge banding machine also includes a lifting seat. The feeding mechanism is arranged on the main machine through the lifting seat, and the height is adjusted by the lifting seat to ensure that the output height of the material is consistent with the position height of the main strip, thereby ensuring the accuracy of the bonding position.

[0033] In any of the above technical solutions, it also includes: a detection device, which is arranged on the main machine, and the detection device is configured to detect the conveying condition of the main strip; a control device, which is electrically connected to the detection device and the feeding mechanism, and the control device is configured to control the operation of the feeding mechanism according to the detection result of the detection device, and adjust the feeding speed of the feeding device.

[0034] In this technical solution, the edge banding machine also includes a detection device and a control device. The detection device is arranged on the main machine and can detect the conveying condition of the main strip; when the detection device detects the main strip, the control device controls the feeding mechanism to work, and then conveys the material to the designated position.

[0035] Specifically, when the detection device detects the head of the main strip, the control device controls the first feeding motor and the second feeding motor of the feeding device to work, thereby driving the material to contact the main strip; when the detection device detects the tail of the main strip, the control device controls the clamping device to clamp the material again, and controls the pushing cylinder of the pushing device to push the clamping device to push the material to the feeding device again, waiting for the next feeding.

[0036] It is worth noting that through the coordinated use of the detection device and the control device, the working time of the feeding mechanism can be accurately controlled, especially the working time and rotation frequency of the first feeding motor and the second feeding motor can be controlled to ensure the accurate position of the material and the main strip.

DETAILED DESCRIPTION

[0042] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0044] Refer to the following Figure 1 The feeding mechanism 100 and the edge banding machine provided according to some embodiments of the present invention are described.

[0045] Embodiment 1:

[0046] like Figure 1 As shown, the feeding mechanism 100 proposed in the first embodiment of the present invention includes a material support plate 102, a limiting device, a clamping device 106, a pushing device and a feeding device.

[0047] Among them, the material pallet 102 can be used to place materials; the limiting device is arranged on the material pallet 102, and a limiting outlet 104 is constructed on the material pallet 102, and the material is stored on one side of the limiting outlet 104; the clamping device 106 is arranged on the material pallet 102, located on one side of the limiting outlet 104, and the clamping device 106 can clamp one of the multiple materials; the pushing device is arranged on the material pallet 102, located on one side of the limiting outlet 104, and the pushing device can push the clamping device 106 to move toward the limiting outlet 104 to drive the material clamped by the clamping device 106 to pass through the limiting outlet 104; the feeding device is located on the other side of the limiting outlet 104, and when the material is pushed to the feeding device, the feeding device can continue to convey the material to a specific position; when one action is completed, the above action is repeated until the entire edge sealing process is completed.

[0048] The feeding mechanism 100 proposed in this embodiment can convey one of the multiple materials to a specific position through the coordinated action of multiple devices, while the remaining materials remain on the material support plate 102. By continuously repeating the above process, the accuracy of the feeding position can be guaranteed, and the feeding position tolerance can be controlled within plus or minus 2 mm.

[0049] Specifically, the feeding mechanism 100 proposed in this embodiment is used to convey the bayonet strip, and can convey the bayonet strip to a specific position, so that the bayonet strip and the main strip after gluing are neatly bonded together, solving the problem that the bayonet strip and the main strip of the edge banding machine cannot be bonded at the same head during the bonding process. By using this feeding mechanism 100 to feed the bayonet strip, the bonding size tolerance of the bayonet strip head can be controlled within plus or minus 2 mm.

[0050] In this embodiment, further, Figure 1 As shown, the limiting device includes a limiting bearing 108 and an adjustment plate 110 .

[0051] There are multiple limit bearings 108, which are distributed along a straight line on the material support plate 102, and form a limit end face at the edge of the material support plate 102; the adjustment plate 110 is arranged on the side of the limit end face, and is spaced apart from the limit end face to form a limit outlet 104. In particular, during the operation of the feeding mechanism 100, the material at the end abuts against the limit end face, and then the material at the end is limited at the side, and the end of the material is opposite to the limit outlet 104, ensuring that the material can pass through the limit outlet 104 under the action of the clamping device 106 and the pushing device; the end of the remaining material abuts against the adjustment plate 110, thereby overcoming the friction between adjacent materials and ensuring that the remaining material remains on the material support plate 102.

[0052] That is, the above limitation can ensure that only one piece of material is pushed at a time, and the above process is repeated continuously to ensure that the pushing process is carried out in an orderly manner. In addition, the adjustment plate 110 and the material support plate 102 are movably connected. Before the feeding mechanism 100 works, the distance between the adjustment plate 110 and the limit end face is adjusted according to the size of the material, so that the size of the limit outlet 104 is about 1 mm larger than the size of the material.

[0053] Specifically, the adjustment plate 110 and the material support plate 102 can be connected through bolts and the strip grooves to ensure that the position of the adjustment plate 110 is adjustable; the limiting end surface is the common section of the multiple limiting bearings 108.

[0054] In this embodiment, further, Figure 1 As shown, the feeding mechanism 100 further includes a pressing cylinder 112 .

[0055] The pressing cylinder 112 and the limit bearing 108 are located at opposite ends of the material support plate 102. During the operation of the feeding mechanism 100, the pressing cylinder 112 works to push the material to the position of the limit bearing 108, so that the material at the end is against the limit end surface, ensuring that the material is relative to the limit outlet 104, and ensuring that the material can pass through the limit outlet 104 under the action of the clamping device 106 and the pushing device.

[0056] In this embodiment, further, Figure 1 As shown, the pushing device includes a linear guide rail 114 and a pushing cylinder 116 .

[0057] Among them, the linear guide 114 is arranged on the material support plate 102, located at the limit outlet 104, and the linear guide 114 is arranged along the extension direction of the limit end surface; the push cylinder 116 is arranged on the material support plate 102, and is connected to the clamping device 106. The clamping device 106 is arranged on the linear guide 114. During the operation of the feeding mechanism 100, the clamping device 106 clamps the material at the end, and the push cylinder 116 drives the clamping device 106 to move along the linear guide 114, thereby driving the material clamped by the clamping device 106 to pass through the limit outlet 104, so as to ensure the orderly feeding.

[0058] In this embodiment, further, Figure 1 As shown, the feeding device includes a first feeding motor 118 , a first feeding wheel 120 , a second feeding motor 122 and a second feeding wheel 124 .

[0059] Among them, the first feeding motor 118 is used in conjunction with the first feeding wheel 120, and can rotate under the drive of the first feeding motor 118; the second feeding motor 122 is used in conjunction with the second feeding wheel 124, and can rotate under the drive of the second feeding motor 122; the first feeding wheel 120 and the second feeding wheel 124 are located at the limit outlet 104, and are respectively located on both sides of the limit outlet 104, and the first feeding wheel 120 and the second feeding wheel 124 have different rotation directions. When the material is pushed into the gap between the first feeding wheel 120 and the second feeding wheel 124, the two sides of the material are respectively in contact with the first feeding wheel 120 and the second feeding wheel 124, and then the first feeding wheel 120 and the second feeding wheel 124 jointly drive the material.

[0060] In particular, since the first feeding wheel 120 and the second feeding wheel 124 are closer to the designated position, and the first feeding wheel 120 and the second feeding wheel 124 first contact the head of the material, the feeding stability can be ensured, and the failure during the feeding process can be effectively reduced to avoid position deviation. In addition, in order to ensure the driving force, the end surfaces of the first feeding wheel 120 and the second feeding wheel 124 are provided with wrinkles or tooth structures.

[0061] Specifically, the first feeding motor 118 and the second feeding motor 122 are both servo motors.

[0062] In this embodiment, further, Figure 1 As shown, the second feeding motor 122 is movably connected to the material support plate 102 , and the feeding mechanism 100 also includes an adjusting cylinder 130 .

[0063] The adjusting cylinder 130 is connected to the second feeding motor 122 and can adjust the distance between the second feeding wheel 124 and the first feeding wheel 120. Before the material passes through the limit outlet 104, the distance between the first feeding wheel 120 and the second feeding wheel 124 is greater than the size of the material, ensuring that the material can smoothly enter between the first feeding wheel 120 and the second feeding wheel 124; when there is a gap between the first feeding wheel 120 and the second feeding wheel 124, the adjusting cylinder 130 drives the second feeding wheel 124 to move toward the first feeding wheel 120, so that the first feeding wheel 120 and the second feeding wheel 124 are in contact with the material, ensuring the driving force for feeding.

[0064] Specifically, the second feeding motor 122 is arranged on the material support plate 102 through the mounting plate 126, and the mounting plate 126 and the material support plate 102 can be connected by a movable connection method such as a slide rail; the first feeding wheel 120 and the first feeding motor 118 are connected by a universal joint transmission shaft 128.

[0065] In this embodiment, further, Figure 1 As shown, the feeding mechanism 100 further includes a pressing rod 132 .

[0066] The pressing rod 132 is arranged on the material support plate 102, and the pressing rod 132, the material pushing device and the material clamping device 106 are located on the same side of the limiting outlet 104. Specifically, there is a certain distance between the pressing rod 132 and the material support plate 102 to ensure the storage of the material; there is a gap of about 2 mm between the pressing rod 132 and the upper surface of the material to ensure the upper limit of the material and the mobility of the material.

[0067] Specifically, the distance between the pressing rod 132 and the material supporting plate 102 is adjustable to accommodate materials of different sizes.

[0068] Embodiment 2:

[0069] The second embodiment of the present invention provides an edge banding machine, comprising a main machine and a feeding mechanism 100 as described above. Therefore, all the beneficial effects of the feeding mechanism 100 are not discussed here one by one.

[0070] Among them, the main machine can convey the main strip, the feeding mechanism 100 is arranged on the main machine, and the conveying direction of the material is perpendicular to the conveying direction of the main strip. The feeding mechanism 100 conveys the material according to the position of the main strip to ensure that the material and the main strip after glue coating are neatly bonded together, thereby solving the problem that the head of the edge banding machine material and the main strip cannot be bonded consistently during the bonding process.

[0071] In this embodiment, further, Figure 1 As shown, the edge banding machine further includes a lifting seat 134. The feeding mechanism 100 is arranged on the main machine through the lifting seat 134, and the height is adjusted through the lifting seat 134 to ensure that the output height of the material is consistent with the position height of the main strip, thereby ensuring the accuracy of the bonding position.

[0072] In this embodiment, the edge banding machine further includes a detection device (not shown in the figure) and a control device (not shown in the figure). The detection device is arranged on the main machine and can detect the conveying condition of the main strip; when the detection device detects the main strip, the control device controls the feeding mechanism 100 to work, and then conveys the material to the designated position.

[0073] It is worth noting that through the coordinated use of the detection device and the control device, the working time of the feeding mechanism 100 can be accurately controlled, especially the working time and rotation frequency of the first feeding motor 118 and the second feeding motor 122 can be controlled to ensure the accurate position of the material and the main strip.

[0074] Specifically, when the detection device detects the head of the main strip, the control device controls the first feeding motor 118 and the second feeding motor 122 of the feeding device to work, thereby driving the material to contact the main strip; when the detection device detects the tail of the main strip, the control device controls the clamping device 106 to clamp the material again, and controls the pushing cylinder 116 of the pushing device to push the clamping device 106, so as to push the material to the feeding device again and wait for the next feeding.

[0075] Specifically, the detection device may adopt components such as infrared sensors and position sensors; the control device may adopt PCL (Programmable Logic Controller). Specific embodiment:

[0077] The feeding mechanism 100 proposed by the present invention is a dual servo card strip feeding mechanism, which is mainly used in woodworking machinery edge banding machines. The feeding mechanism 100 can synchronously with the main strip feeding motor to feed the bayonet strip to a specific position, so as to be neatly bonded with the main strip after gluing, solving the problem that the bayonet strip of the edge banding machine and the main strip cannot be bonded uniformly at the head during the bonding process. By using this feeding mechanism 100 to feed the bayonet strip, the head bonding size tolerance can be controlled within plus or minus 2 mm.

[0078] The specific working principle is as follows: First, according to the thickness of the bayonet strip, adjust the adjustment plate 110 so that the distance between the adjustment plate 110 and the cross section of the limit bearing 108 is greater than the thickness of the bayonet strip by about 1mm, so that a single bayonet strip can pass through this distance. Then, arrange several bayonet strips neatly on the material support plate 102 that can adjust the height, with the head of the bayonet strip close to the adjustment plate 110, and the side of the bayonet strip close to the limit bearing 108, and manually open the valve of the clamping cylinder 112, and the clamping cylinder 112 works to press the multiple bayonet strips tightly on the specific position of the material support plate 102. Then adjust the pressure rod 132 so that there is a gap of about 2mm between the pressure rod 132 and the bayonet strip.

[0079] After pressing the start switch, the control device PLC sends a signal to the clamping device 106 to start working, and the single bayonet strip is clamped. Under the action of the pushing cylinder 116, the single bayonet strip is passed through the first feeding wheel 120 and the second feeding wheel 124 along the linear guide 114, and is sent out in a straight line to a distance equal to the stroke of the pushing cylinder 116. Under the action of the adjusting cylinder 130, the first feeding wheel 120 and the second feeding wheel 124 are adjusted to clamp the bayonet strip, the clamping device 106 is opened, and the pushing cylinder 116 starts working, and the linear guide 114 of the clamping device 106 moves back to the origin to wait for the cycle signal.

[0080] A detection device is installed on the main machine. When the detection device detects that the main strip is coming, the control device PLC simultaneously gives working signals to the first feeding motor 118 and the second feeding motor 122. Because the second feeding wheel 124 is directly installed on the output shaft of the second feeding motor 122, the first feeding wheel 120 transmits power from the first feeding motor 118 to the first feeding wheel 120 through the connection of the universal joint transmission shaft 128. The first feeding motor 118 and the second feeding motor 122 rotate in opposite directions. Under the rotation force of the first feeding wheel 120 and the second feeding wheel 124, the bayonet strip is uniformly transported forward at a set speed.

[0081] Since the main strip conveying speed is fixed, a speed can be matched by adjusting the rotation speed of the first feeding motor 118 and the second feeding motor 122, so that the bayonet strip and the main strip can be neatly bonded together at the head of the fixed position. When the first feeding motor 118 and the second feeding motor 122 stop running after the set time, after the tail of the main strip passes the detection device, the control device PLC sends a circulation signal to the clamping device 106 to perform a circulation operation.

[0082] In the description of the present invention, the term "plurality" refers to two or more than two. Unless otherwise clearly defined, the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. The terms "connection", "installation", "fixation", etc. should be understood in a broad sense.
