Description

Technical Field

[0001] The invention relates to the technical field of heat insulation cotton processing, in particular to a heat insulation cotton cutting device capable of automatically calibrating a cutting position. Background Art

[0002] Thermal insulation cotton is usually installed under the hood of the car. It has the functions of sound insulation, heat insulation, anti-resonance, and preventing paint from changing color at high temperature. It can prevent water vapor from rising on rainy days. It has a heat preservation effect when the car is parked outdoors in the north for two hours in winter. The sound insulation cotton covers a large area on the car. Therefore, the size of the sound insulation cotton in different areas is also different. This requires the car thermal insulation cotton to be cut to the appropriate size through a cutting device during production.

[0003] There are many existing technologies for thermal insulation cotton cutting devices, such as:

[0004] Chinese patent announcement number CN117206713B discloses a power battery insulation cotton cutting device with position adjustment function. It includes an insulation cotton placement heating rack, the surface of which is provided with a laser moving cutting component, which is used to use laser cutting on the insulation cotton; the surface of the insulation cotton placement heating rack is provided with an insulation cotton feeding position adjustment component, which is used to adjust the cutting position of the insulation cotton; the scraped wire core is separated from the insulation cotton placement heating rack by a fixed blade, so as to ensure the flatness of the insulation cotton placement heating rack when the insulation cotton moves, avoid the accumulation of too many wire cores causing the surface of the insulation cotton placement heating rack to bulge, and the bulge will scratch the insulation cotton, and at the same time, the fixed blade controls the distance between the insulation cotton on both sides to avoid the distance being too close, so that some wire ends contact the insulation cotton at the other end before cooling, and avoid the insulation cotton on both sides to establish connection again.

[0005] It can be seen that when the thermal insulation cotton is cut, the cut thread ends are cut with a blade to prevent the uncooled surface of the thread ends from fusing with the thermal insulation cotton. Therefore, when the uncooled thread ends adhere to the thermal insulation cotton placement heating rack, since the thermal insulation cotton at the feed end is in contact with the thermal insulation cotton placement heating rack, if it is cut directly horizontally, the fitted thermal insulation cotton will be scratched by the blade, thereby affecting its subsequent use. Secondly, after cutting, the conveying device conveys the cut thermal insulation cotton, and at this time, the cut portion of the thermal insulation cotton is in contact with the thermal insulation cotton placement heating rack, causing the thermal insulation cotton to bend, affecting the efficiency of subsequent cutting. Summary of the invention

[0006] The object of the present invention is to provide a thermal insulation cotton cutting device which can automatically calibrate the cutting position, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention aims to provide a heat insulation cotton cutting device with automatic calibration of cutting position, including a processing table and a laser cutting device placed horizontally on the processing table, the laser cutting device is driven by a driving device arranged beside the processing table, and support plates are symmetrically arranged in the middle of the processing table, both side support plates are provided with turning parts, and there is a support member between the two side support plates, a cutting knife arranged above the support member is slidably connected to the processing table, the two ends of the support member are rotatably connected to the top plate, the end of the top plate is rotatably connected to the inner wall of the processing table, and the other end is fitted with the expansion part, and an ejection part is arranged beside the expansion part and at the bottom of the support member, and the ejection part includes a support rod and a top column located at both ends of the support rod;

[0008] The cutting knife moves downward to push the support member to squeeze the top plate, and the expansion part expands to push the insulation cotton at the feeding end of the cutting side upward, so that the insulation cotton tilts upward;

[0009] The expansion of the expansion part drives the top column and the support rod to rotate, so that after the cutting knife is separated from the support member, the support member is moved by the support rod to tilt it downward, and the impurities on the support member are poured out.

[0010] As a further improvement of the technical solution, an alarm is provided beside the laser cutting device, and an infrared sensor for calibrating the laser head is provided just above the cutting knife, and the infrared sensor is fixed on the inner wall of the processing table.

[0011] As a further improvement of the present technical solution, the flipping part includes a limit piece and a flipping column. The limit piece is triangular in shape and is used to press the thermal insulation cotton and fit it with a support plate fixedly connected to the processing table. The limit piece is fixedly connected to multiple sliding rods. The first spring sleeved on each sliding rod is against the flipping column, and the sliding rod is slidably connected to the flipping column. The output shaft of the auxiliary motor is coaxially connected to the flipping column, and the auxiliary motor is located on the outer wall of the processing table.

[0012] As a further improvement of the present technical solution, the expansion part is composed of an airbag ball and an airbag cushion, the airbag ball and the airbag cushion are connected by an air tube, and the airbag ball is arranged on a base fixedly connected to the processing table, the airbag cushion is embedded in the support plate at the feed end and close to the support member, the top plate squeezes the airbag ball to expand the airbag ball and inflate the airbag cushion, and the expanded airbag cushion pushes the insulation cotton on one side of the feed end upward to form an inclined insulation cotton.

[0013] As a further improvement of the present technical solution, a first push rod is also arranged next to the airbag ball, the bottom of the first push rod is fixedly connected to the second push rod, the second push rod is slidably connected to a ring arranged on the inner wall of the processing table, the ring is slidably connected to the second push rod, the inflated airbag ball is used to push the first push rod to move, and the second spring on the second push rod is compressed, and the airbag ball is separated from the first push rod by a distance.

[0014] As a further improvement of the technical solution, the movement of the first push rod will also drive the movement of a rack fixedly connected to the side, and the rack drives the gear body meshing with it to rotate. The gear body rotates and is connected to the processing table, so that the support rod coaxially connected to the top of the gear body drives the push column to rotate, and the push column close to the airbag cushion is lower than the height of the push column on the other side, so that the lowered support member is against the two push columns, thereby forming a state in which the support member is tilted toward the feed end.

[0015] As a further improvement of the technical solution, the third spring sleeved at the bottom of the top column is against the support rod. When the support rod rotates, the support member flips over and squeezes the top column close to the airbag cushion, so that the top column lifts up the raised side of the support member, causing the support member to tilt.

[0016] As a further improvement of the present technical solution, a support seat is provided in the middle of the top plate for supporting the rotating shafts at both ends of the support member, and the rotating shafts are rotatably connected to the support seat. When the cutting knife pushes the support member downward, the thermal insulation cotton adhered to the support member cooperates with the auxiliary effect of the airbag cushion to tilt the thermal insulation cotton.

[0017] As a further improvement of the technical solution, the ends of the stabilizing rods on both sides of the sliding connection of the cutting knife are fixedly connected, and the protrusions provided at the ends of the stabilizing rods are used to limit the fit between the cutting knife and the ends of the stabilizing rods, so that the plug plates provided on both sides of the laser head push the cutting knife to move.

[0018] As a further improvement of the technical solution, the ends of the stabilizing rods on both sides are slidably connected to columns, the columns are fixed on the inner wall of the processing table, and the fourth springs sleeved on the columns are against the bottom of the stabilizing rods.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the thermal insulation cotton cutting device with automatic calibration of the cutting position, the cutting knife is pushed downward by the laser cutting device, the support member squeezes the top plate, the top plate rotates to squeeze the airbag ball, and inflates the airbag cushion. At this time, the expanded airbag cushion pushes the thermal insulation cotton at the feeding end upward, and cooperates with the downward movement of the support member to make the insulation cotton adhered to the support member rise, so that the laser cutting device is used to drive the cutting knife to slide on the support member, and the thermal insulation cotton adhered to the support member is separated from the support member, and the thermal insulation cotton is protected, so as to prevent the thermal insulation cotton from bending and affecting the feeding efficiency when feeding again.

[0021] 2. In the thermal insulation cotton cutting device with automatic calibration of the cutting position, after the thermal insulation cotton on the support is separated, the driving device continues to push the support downward and contacts the highest top column. At this time, the other end of the top column is tilted downward to pour out the impurities on the support, and cooperates with the rack pushed out by the airbag ball to drive the gear body to rotate, so that the top column on the other side contacts the bottom of the support, thereby increasing the inclination of the support so that the impurities can be separated from the support.

[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, a heat-insulating cotton cutting device for automatically calibrating a cutting position is provided, comprising a processing table 100 and a laser cutting device 101 placed horizontally on the processing table 100. The laser cutting device 101 is driven by a driving device 105 arranged beside the processing table 100 (the driving device 105 is the same as that in the prior art, mainly comprising a driving motor, a ball screw and a pair of meshing bevel gears). The driving device 105 is used to move the laser cutting device 101 on the processing table 100 to calibrate the cutting position. Therefore, when the laser cutting device 101 blocks the infrared sensor 104 arranged just above the cutting blade 108, at this time, an alarm 102 arranged beside the laser cutting device 101 is used, and the alarm 102 sounds an alarm and serves as a prompt. Secondly, the operation and start and stop of the driving device 105 are controlled by a control system arranged on the processing table 100, so as to achieve accurate calibration of the cutting position.

[0042] Next, a support plate 103 is symmetrically arranged in the middle of the processing table 100, and a support member 106 is provided between the support plates 103 on both sides. A cutting knife 108 is provided above the support member 106 and is slidably connected to a stabilizing rod 109. Both ends of the support member 106 are rotatably connected to a top plate 107. The end of the top plate 107 is rotatably connected to the inner wall of the processing table 100, and the other end is fitted with the expansion portion 300. Therefore, when cutting, the thermal insulation cotton is fixed by two sets of flipping parts 200 to prevent the thermal insulation cotton from shifting during cutting. After the cutting is completed, the thermal insulation cotton at the cutting location is at high temperature, and the thread ends are not completely cooled, which can easily cause the thread ends at the cutting location to adhere to the support member 106, thereby affecting the later separation of the thermal insulation cotton and the support member 106.

[0043] Therefore, the cutting knife 108 is moved downward to push the support member 106 to squeeze the top plate 107, so that the top plate 107 is away from one end of the rotating connection processing table 100 to squeeze the expansion part 300. The squeezed expansion part 300 expands and pushes the insulation cotton at the feeding end of the cutting side upward, and the insulation cotton adhered to the support member 106 is tilted upward at this time (that is, the insulation cotton at the feeding end is away from the support plate 103). In this way, under the action of the laser cutting device 101, the cutting knife 108 can be driven to move on the support member 106, thereby separating the adhered insulation cotton from the support member 106, preventing the cutting knife 108 from scratching the insulation cotton, and secondly, preventing the adhered insulation cotton from bending and affecting the feeding progress.

[0044] In order to fix the insulation cotton during cutting and to transfer the cut insulation cotton after cutting, based on the above structure, Figure 3 and Figure 4The structure of the flipping part 200 is further disclosed. The flipping part 200 includes a limit member 201 and a flipping column 202. The limit member 201 is triangular in shape. When the thermal insulation cotton is placed at the feed end and close to the limit member 201, the auxiliary motor 210 arranged on the outside of the processing table 100 is used to drive the coaxially connected flipping column 202 to rotate, so that the limit member 201 fixedly connected to multiple sliding rods 211 intermittently retracts into the flipping column 202, and when the limit member 201 rotates to the closest distance to the support plate 103, the limit member 201 squeezes the first spring 212 mounted on each sliding rod 211, so that the limit member 201 presses the thermal insulation cotton and fits with the support plate 103 fixedly connected to the processing table 100.

[0045] Furthermore, after the thermal insulation cotton is fixed, the laser head is moved downward and toward the other end of the processing table 100 to cut the thermal insulation cotton. Secondly, after the thermal insulation cotton is cut, the thermal insulation cotton on the opposite side of the feed end is separated from the support plate 103, and the thermal insulation cotton at the feed end moves toward the cutting position so that the cutting operation can be performed again.

[0046] Before the insulation cotton on the feeding end side is moved, the temperature will cause the insulation cotton to adhere to the support member 106 at the cutting position, and then the insulation cotton will bend when being transported, affecting the cutting of the insulation cotton.

[0047] In order to ensure the normal feeding, when the support member 106 is separated from the heat insulation cotton, the ends of the stabilizing rods 109 on both sides connected by the sliding connection of the cutting knife 108 are fixedly connected (cooperating with the cutting knife 108). Figure 8 As shown, the protrusion at the end of the stabilizing rod 109 is used to limit the fit between the cutting knife 108 and the end of the stabilizing rod 109, and there are plug-ins on both sides of the laser head, so that the plug-in board can be inserted beside the protrusion, and the laser head moves downward to push the cutting knife 108 to move. At the same time, the thermal insulation cotton at the feed end is transported to the support 106, and an angle is formed between the adhered thermal insulation cotton and the support plate 103, so that the thermal insulation cotton is in a state of being separated from the support 106 (the thermal insulation cotton in this process changes from being fitted to being tilted), so that the cutting knife 108 can separate it from the support 106 later.

[0048] As the support member 106 moves downward, the rotating shafts at both ends of the support seat support member 106 squeeze the support seat set in the middle of the top plate 107, and the rotating shafts rotate to connect the support seat. Therefore, when the top plate 107 rotates to squeeze the expansion part 300, the expanded expansion part 300 pushes the insulation cotton at the feeding end upward, thereby increasing the inclination angle of the insulation cotton and making the insulation cotton away from the support plate 103 at the feeding end, so that the plug plate on one side of the laser head drives the cutting knife 108 to slide on the stabilizing rod 109 to separate the adhered insulation cotton from the support member 106, thereby preventing bending during the later feeding and affecting the feeding efficiency.

[0049] Therefore, returning to Figure 7 , the specific structure of the expansion part 300 is disclosed. The expansion part 300 is composed of an airbag ball 301 and an airbag cushion 302. The airbag ball 301 and the airbag cushion 302 are connected by an air tube, and the airbag ball 301 is arranged on a base fixedly connected to the processing table 100. The airbag cushion 302 is embedded in the feed end support plate 103 and close to the support member 106. The top plate 107 is used to squeeze the airbag ball 301 to expand the airbag ball 301 and inflate the airbag cushion 302. The expanded airbag cushion 302 pushes the insulation cotton on one side of the feed end upward, thereby pushing out the insulation cotton attached to the support plate 103, so as to leave enough angle for the cutting shears 108 to cut the insulation cotton.

[0050] Specifically, during operation, the plug plate is inserted into one side of the protrusion and moves horizontally to one side through the plug plate, thereby driving the cutting knife 108 to move and separate the heat insulation cotton and the support member 106 .

[0051] The above is Example 1 of the present invention. Next, Figure 5-Figure 7 Embodiment 2 of the present invention is shown.

[0052] First, the specific structure of the ejection part 400 is disclosed. The ejection part 400 includes a support rod 411 and ejection columns 410 located at both ends of the support rod 411 .

[0053] After the insulation cotton is cut (i.e., the support member 106 is about to detach from the two side support plates 103 at this time), the cutting knife 108 continues to push the support member 106 downward, so that the support member 106 is completely detached from the two side support plates 103, and the bottom side of the detached support member 106 contacts the top column 410 away from the feed end. The purpose of this is: using the downward movement of the support member 106 to make the top column 410 and one side of the support member 106 collide with each other, so that the side of the support member 106 close to the feed end can be tilted downward, which is convenient for dumping impurities on the surface of the support member 106, so as to ensure that the quality and performance of the cutting edge are not affected, and prevent impurities from affecting the further cutting of the insulation cotton.

[0054] Next, since the top column 410 close to the airbag cushion 302 is lower than the top column 410 on the other side, as the height of the support member 106 decreases, the inclination of the support member 106 also increases, and the bottom of the first top rod 401 provided beside the airbag ball 301 is fixedly connected to the second top rod 402, and the second top rod 402 is slidably connected to the ring provided on the inner wall of the processing table 100, and the ring is slidably connected to the second top rod 402, and the airbag ball 301 is separated from the first top rod 401 by a distance.

[0055] It should be noted that: when the top plate 107 just starts to squeeze the airbag ball 301, the airbag ball 301 is compressed to inflate into the airbag cushion 302. At this time, the airbag ball 301 does not contact the first push rod 401, but when the shortest top column 410 contacts the bottom of the other side of the support member 106, the airbag ball 301 contacts the first push rod 401 (the reason is that: when the airbag cushion 302 expands for a while and reaches the maximum expansion degree, the airbag cushion 302 will no longer expand, and at this time the top plate 107 continues to squeeze the airbag ball 301, and the squeezed airbag ball 301 expands and contacts the first push rod 401).

[0056] Therefore, the inflated airbag ball 301 is utilized to push the first top rod 401 to move, and the first top rod 401 moves and drives the rack 403 fixedly connected at the bottom to move, and the rack 403 drives the gear body 404 meshing therewith to rotate, so that the support rod 411 coaxially connected to the top of the gear body 404 drives the top column 410 to rotate, and the top column 410 moves the other side of the support member 106 to rotate, thereby increasing the inclination amplitude of the support member 106, so as to facilitate the separation of impurities on the support member 106 from the support member 106, and prevent the impurities from affecting the cutting of the thermal insulation cotton.

[0057] In the above process, the first push rod 401 compresses the second spring 405 sleeved on the second push rod 402, and the third spring 412 sleeved on the bottom of the top column 410 abuts against the support rod 411. When the impurities on the support member 106 are dumped, the laser cutting device 101 is released from the downward pressure on the cutting blade 108 (cooperating with the laser cutting device 101). Figure 8 As shown, because the ends of the stabilizer bars 109 on both sides of the stabilizer bars 109 are slidably connected to the columns, and the columns are fixed on the inner wall of the processing table 100, therefore, under the elastic action of the fourth spring 110 sleeved on the columns, the fourth spring 110 pushes the stabilizer bars 109 to make the cutting knife 108 separate from the support member 106, and the gas in the airbag cushion 302 is transported to the airbag ball 301, causing the top plate 107 to rotate in the opposite direction, thereby pushing the support member 106 to pass through the support plates 103 on both sides until the support member 106 and the cutting knife 108 are against each other. At this time, the support plate 103 rotates to a state flush with the support plates 103 on both sides, so as to facilitate the cutting of the insulation cotton at the feed end again.

[0058] At the same time, during the upward movement of the support member 106, the inclined support member 106 can also push out the insulation cotton at the feed end, and the support member 106 away from the feed end is inclined upward to prevent the cut part of the insulation cotton that has separated from the support member 106 from falling into the bottom of the support plate 103 on the other side of the feed end, that is, the cut part of the insulation cotton is located at the bottom of the support plate 103 away from the feed end. In this way, when the support member 106 moves upward, the insulation cotton will block the rise of the support member 106, thereby affecting the cutting efficiency.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
