Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for processing automotive foam tape. Background Technology

[0002] In the automotive manufacturing and related parts processing fields, automotive foam tape is widely used, such as for bonding automotive interiors, sealing the car body, and fixing electronic components. During the production of foam tape, a cutting device is needed for quantitative cutting. Among them, a cutting device for processing foam tape is disclosed in Chinese utility model patent with announcement number CN221051150U. Although this device solves the problem of synchronous cutting of tape winding by means of a cutting mechanism, the cutting mechanism in this device is too complex and scattered, which increases the installation and stabilization cost of the cutting mechanism. In addition, the motor and pull rope remotely control the cutter, which increases the energy consumption of the motor drive. Furthermore, there is a risk of pull rope breakage, which affects the cutting of foam tape.

[0003] Secondly, the compression force during the cutting of foam tape can easily cause the roll and the rolled foam tape to jump and shift. This results in rough cuts when slitting the foam tape, which is inconvenient in actual use and can also lead to errors in the cutting dimensions of the foam tape. Utility Model Content

[0004] This utility model discloses a cutting device for processing automotive foam tape. The operator starts the cylinder, and the cylinder push rod moves upward through the controller or manual control button. The push rod drives the rack to rise, and the rack meshes with the drive gear, so that the drive gear starts to swing clockwise. The drive gear drives the cutter to swing upward, so that the cutter leaves the surface of the cutting platform, leaving space for the tape to move forward. According to the required cutting length, the automotive foam tape is manually or automatically conveyed forward to the appropriate position to ensure that the cutting size is accurate.

[0005] Once the tape is in place, the cylinder is activated again, causing the cylinder push rod to move downwards. The push rod drives the rack to descend, which in turn drives the drive gear to swing counterclockwise. The drive gear then drives the cutter to swing downwards rapidly. With the help of the cylinder's thrust and its own inertia, the cutter quickly cuts the automotive foam tape. As the cutter swings downwards, the rack drives the positioning frame to descend. The locking plate on the positioning frame moves upwards under the action of the support spring, engaging with the locking block at the end of the friction rod on one side of the positioning roller. This locks the positioning roller, preventing it from jumping or shifting during tape cutting, ensuring cutting accuracy and stability.

[0006] In a first aspect, this disclosure provides a cutting device for processing automotive foam tape, specifically comprising: a cutting platform, wherein a set of through holes is formed in the middle of the cutting platform, two stabilizing frames connected by hinges are installed at the upper position of the cutting platform, a positioning roller is installed at the bottom position of the two stabilizing frames, a cutting mechanism is installed on one side of the cutting platform at the position of a sliding hole, the cutting mechanism is composed of a cylinder, a rack, a drive gear and a cutter, a stabilizing hole is formed at the bottom position of the cutting platform, a cylinder is installed at the inner side of the stabilizing hole, and a locking structure is installed at the outer side of the rack, the locking structure is composed of a positioning frame, a positioning bolt and a locking plate.

[0007] Furthermore, two symmetrically distributed positioning seats are installed above the cutting platform. A set of bolt mounting holes is opened between the cutting platform and the positioning seats. A rotating hole is opened in the middle of the positioning seat. A rotating shaft is provided on each side of the drive gear, and the rotating shaft passes through the interior of the rotating hole.

[0008] Furthermore, a positioning groove is opened on each of the two sides above the cutting platform. A set of friction rollers is installed on the inner side of the positioning groove and the stabilizing frame, and a friction rod is provided on each side of the positioning roller. The friction rod is installed between the two sets of friction rollers.

[0009] Furthermore, a sliding hole is opened on one side of the stabilizing frame. The sliding hole has a cylindrical structure. Two locking slots are opened above the cutting platform, which are aligned with the sliding hole. The locking rod passes through the sliding hole and extends into the interior of the locking slot. A support spring and a retaining ring are installed on the outside of the locking rod.

[0010] Furthermore, a stabilizing plate is provided on the upper position of the cylinder push rod, a rack is installed on the upper position of the stabilizing plate, and a bolt mounting hole is opened at the bottom position of the rack and on both sides of the stabilizing plate.

[0011] Furthermore, a mounting groove is formed on one side of the drive gear, and one side of the cutter is installed inside the mounting groove. A locking bolt is installed between the drive gear and the cutter.

[0012] Furthermore, a positioning bracket is installed on the outer side of the rack. A set of horizontal bolt mounting holes is opened on one side of the positioning bracket, and two vertical sliding holes are opened on the other side of the positioning bracket. Two threaded grooves are opened at the bottom of the locking plate, and two positioning bolts with support springs are installed between the sliding holes and the threaded grooves.

[0013] Furthermore, the friction rod on one side of the positioning roller is provided with a set of locking blocks at its end. The locking blocks are arc-shaped or rectangular. A set of locking grooves corresponding to the locking blocks are opened above the locking plate.

[0014] This utility model provides a cutting device for processing automotive foam tape, which has the following beneficial effects:

[0015] The cutting mechanism consists of a cylinder, rack, drive gear, and cutter. This structural design ensures that the cutter moves accurately and stably during the cutting process. The cylinder, as the power source, provides stable thrust. Through the precise meshing of the rack and drive gear, the cutter can swing rapidly along a predetermined trajectory to precisely cut the automotive foam tape.

[0016] Compared with traditional manual and mechanical cutting mechanisms, it greatly improves the cutting accuracy, reduces tape waste caused by cutting errors, and has the advantages of simple and compact structure compared with traditional mechanical cutting mechanisms. It also improves the quality stability of products and meets the production requirements for high-precision cutting of automotive foam tape.

[0017] Operators can flexibly adjust the cylinder parameters according to different tape materials, thicknesses, and cutting size requirements, so as to precisely control the oscillation frequency and interval of the cutter and further optimize the cutting process.

[0018] A locking structure consisting of a positioning frame, positioning bolts, and a locking plate is set on the rack. When the cutter swings downward, the locking plate moves upward under the drive of the positioning frame, so that the locking groove of the positioning frame and the locking block are engaged. At this time, the positioning frame can lock the positioning roller, avoiding the phenomenon of the positioning roller jumping and displacement when the cutter cuts the automotive foam tape. With the cooperation of the support spring, the cutter can effectively cut the automotive foam tape during the process of locking the positioning roller. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1: Please refer to Figures 1 to 9 :

[0039] This utility model discloses a cutting device for processing automotive foam tape, comprising: a cutting platform 1, a set of through holes in the middle of the cutting platform 1, two stabilizing frames 2 connected by hinges installed on the upper part of the cutting platform 1, achieving the effect of hinged positioning of the stabilizing frames 2 with the cooperation of the hinges, and a positioning roller 3 installed at the bottom of the two stabilizing frames 2. The operator installs the automotive foam tape to be cut on the positioning roller 3 for positioning, and the installed automotive foam tape needs to be in a wound state. A positioning groove is opened on each of the two sides of the upper part of the cutting platform 1, and a set of friction rollers is installed on the inner side of the positioning groove and the stabilizing frame 2 respectively. A friction rod is provided on each side of the positioning roller 3, and the friction rod is installed between the two sets of friction rollers. Therefore, it can be concluded that the positioning groove, the stabilizing frame 2, and the friction roller work together to stabilize the rotation position of the positioning roller 3, allowing the positioning roller 3 to rotate stably in place. A sliding hole is opened on one side of the stabilizing frame 2. The sliding hole is a cylindrical structure. Two locking grooves are opened above the cutting platform 1, which are aligned with the sliding hole. The locking rod 201 passes through the sliding hole and extends into the interior of the locking groove. A support spring and a snap ring are installed on the outside of the locking rod 201. Therefore, the locking rod 201, together with the spring, achieves the effect of stabilizing the stabilizing frame 2 after locking. The worker can unlock the stabilizing frame 2 by pulling the locking rod 201 outward. At this time, the positioning roller 3 can be flexibly disassembled and installed, and the positioning roller 3 can be easily replaced.

[0040] In this embodiment of the disclosure, reference is made to Figures 1 to 9 As shown, a cutting mechanism 4 is installed on one side of the cutting platform 1 at the position of the sliding hole. The cutting mechanism 4 is composed of a cylinder 401, a rack 402, a drive gear 403, and a cutter 404. Two symmetrically distributed positioning seats 101 are installed above the cutting platform 1. A set of bolt mounting holes is opened between the cutting platform 1 and the positioning seats 101. The operator installs a set of bolts between the bolt mounting holes to achieve the effect of stabilizing the installation position of the positioning seats 101. A rotating hole is opened in the middle of the positioning seat 101. A rotating shaft is provided on each side of the drive gear 403. The rotating shaft passes through the interior of the rotating hole. The positioning seat 101, together with the rotating hole and the rotating shaft, achieves the effect of positioning the installation position of the drive gear 403. After positioning, the drive gear 403 rotates stably in place at the position of the rotating hole in conjunction with the rotating shaft.

[0041] In this embodiment of the disclosure, reference is made to Figures 1 to 9As shown, a stabilizing hole is made at the bottom of the cutting platform 1. A cylinder 401 is installed inside the stabilizing hole. The stabilizing hole ensures a stable installation position. The operator can install bolts on the stabilizing hole to further stabilize the cylinder 401. A stabilizing plate is provided above the push rod of the cylinder 401. A rack 402 is installed above the stabilizing plate. A bolt mounting hole is made at the bottom of the rack 402 and on both sides of the stabilizing plate. After the operator installs bolts in the bolt mounting holes, the push rod and rack 402 are stably assembled. Therefore, the operator can stably control the rack by controlling the cylinder 401. 402 moves up and down, driving gear 403 and rack 402 mesh, so rack 402 can control drive gear 403 to swing back and forth when it rises and falls. A mounting groove is opened on one side of drive gear 403, and one side of cutter 404 is installed inside the mounting groove. A locking bolt is installed between drive gear 403 and cutter 404. The locking bolt and the mounting groove achieve the effect of stable assembly of drive gear 403 and cutter 404. In addition, the mounting groove facilitates the replacement of cutter 404. When drive gear 403 swings, it can drive cutter 404 to swing. After the cutter 404 swings down, it can quickly cut the automotive foam tape with the help of cylinder 401.

[0042] In this embodiment of the disclosure, reference is made to Figures 1 to 9 As shown, a locking structure 5 is installed on the outer side of the rack 402. The locking structure 5 consists of a positioning bracket 501, positioning bolts 502, and a locking plate 503. A positioning bracket 501 is installed on the outer side of the rack 402. A set of horizontal bolt mounting holes is opened on one side of the positioning bracket 501. The operator uses a wrench to install bolts at the bolt mounting holes to stably assemble the rack 402 and the positioning bracket 501, so that the rack 402 can drive the positioning bracket 501 to move up and down stably when lifting. Two vertical sliding holes are opened on the other side of the positioning bracket 501. Two threaded grooves are opened at the bottom of the locking plate 503. Two positioning bolts 502 with support springs are installed between the sliding holes and the threaded grooves. The positioning bolts 502 achieve positioning after installation. The positioning effect between the frame 501 and the locking plate 503 is achieved by the support spring elastically supporting the locking plate 503 upwards. The friction rod on one side of the positioning roller 3 has a set of locking blocks at its end. The locking blocks are arc-shaped or rectangular. A set of locking grooves corresponding to the locking blocks are opened on the upper part of the locking plate 503. When the cutter 404 swings downwards, the locking plate 503 moves upwards under the drive of the positioning frame 501, so that the locking groove of the positioning frame 501 and the locking block are engaged. At this time, the positioning frame 501 can lock the positioning roller 3, avoiding the phenomenon of the positioning roller 3 jumping and displacing when the cutter 404 cuts the automotive foam tape. With the cooperation of the support spring, the cutter 404 can effectively cut the automotive foam tape during the locking process of the positioning roller 3.

[0043] Example 2, based on Example 1, with reference to Figures 1 to 9 As shown, the operator needs to set up a controller based on the existing technology on the basis of cylinder 401. By operating the controller, the operator controls the push rod of cylinder 401 to move up and down. The operator needs to set a parameter on the controller to accurately control the swing frequency and interval of the cutter 404.

[0044] The working principle of this embodiment:

[0045] The assembly and debugging steps of the cutting device are as follows: The operator installs two positioning seats 101 at the designated positions above the cutting platform 1 and uses bolts to firmly install the positioning seats 101 on the cutting platform 1. The operator passes the rotating shaft of the drive gear 403 through the rotating hole of the positioning seat 101. The drive gear 403 can rotate stably in place on the positioning seat 101. Check its rotation flexibility and stability. If necessary, add appropriate lubricating oil for lubrication to ensure smooth rotation.

[0046] The worker picks up the stabilizing frame 2 and installs it above the cutting platform 1 using hinges. Positioning rollers 3 are installed at the bottom of the stabilizing frame 2, ensuring that the friction rods on both sides of the positioning rollers 3 are accurately installed between the positioning groove and the friction rollers inside the stabilizing frame 2. This ensures that the rotation position of the positioning rollers 3 is stable both vertically and vertically, allowing them to rotate stably in place. The worker then installs the cylinder 401 into the stabilizing hole at the bottom of the cutting platform 1. Bolts can be installed on top of the stabilizing hole as needed to further stabilize the position of the cylinder 401, ensuring that the cylinder 401 is securely installed. A stabilizing plate is placed above the push rod of the cylinder 401, and a rack 402 is installed on the stabilizing plate, ensuring that the bottom of the rack 402 is tightly fitted to the stabilizing plate. Bolts are used to fix both, ensuring that the push rod and rack 402 are securely assembled and that the rack 402 can move stably up and down as the push rod of the cylinder 401 extends and retracts.

[0047] The operator installs the cutter 404 into the mounting slot of the drive gear 403 and secures it firmly with locking bolts to ensure that the cutter 404 will not loosen or fall off when the drive gear 403 swings. Simultaneously, the operator checks the installation angle and position of the cutter 404 to ensure it can accurately cut automotive foam tape. A positioning bracket 501 is installed on the outside of the rack 402 and fixed to the rack 402 with bolts to ensure that the positioning bracket 501 can move freely when the rack 402 rises and falls. Move the locking plate 503 stably up and down and install it on the positioning frame 501. Make the positioning bolt 502 pass through the sliding hole of the positioning frame 501 and screw it into the thread groove of the locking plate 503. Install the support spring on the positioning bolt 502. The support spring can elastically support the locking plate 503 upward. Check whether the locking function of the locking plate 503 is normal and ensure that it can accurately engage with the locking block at the end of the friction rod on one side of the positioning roller 3 when the cutter 404 swings downward, so as to achieve reliable locking of the positioning roller 3.

[0048] For Embodiment 2, the operator needs to install a controller on the basis of cylinder 401, install it according to the controller's installation instructions, correctly connect the controller to the control interface of cylinder 401, set the relevant parameters on the controller, and precisely adjust the swing frequency and interval of the cutter 404 according to the material and thickness of the automotive foam tape to ensure the best cutting effect. The parameters can be fine-tuned through trial operation to achieve the ideal cutting effect and efficiency.

[0049] The staff installs the automotive foam tape roll that needs to be cut onto the positioning roller 3, ensuring that the tape roll is firmly installed and that the center hole fits tightly with the positioning roller 3. The tape roll can rotate freely with the rotation of the positioning roller 3 without any deviation or shaking during the rotation. The tape is stretched so that one end of the tape extends below the cutter 404 so that the cutter 404 can accurately cut the tape. At the same time, it is ensured that the tape is not subjected to additional pulling or twisting during the cutting process, thus guaranteeing the accuracy and quality of the cutting.

[0050] The tape cutting operation involves the operator activating cylinder 401. Using a controller or manual control button, the push rod of cylinder 401 moves upward, causing rack 402 to rise. Rack 402 meshes with drive gear 403, causing drive gear 403 to begin oscillating clockwise. Drive gear 403 then drives cutter 404 to oscillate upward, lifting it off the cutting platform 1 surface and creating space for the tape to advance. Depending on the required cutting length, the automotive foam tape is manually or automatically fed forward to the appropriate position using a feeding mechanism connected to the controller, ensuring accurate cutting dimensions.

[0051] Once the tape is in place, cylinder 401 is activated again, causing the push rod of cylinder 401 to move downwards. The push rod drives rack 402 to descend, and rack 402 drives drive gear 403 to swing counterclockwise. Drive gear 403 drives cutter 404 to swing downwards rapidly. With the help of the thrust of cylinder 401 and its own inertia, cutter 404 quickly cuts the automotive foam tape. During the downward swing of cutter 404, rack 402 drives positioning frame 501 to descend. Locking plate 503 on positioning frame 501 moves upwards under the action of support spring and engages with locking block at the end of friction rod on one side of positioning roller 3 to lock positioning roller 3, preventing positioning roller 3 from jumping or displacing when cutter 404 cuts tape, thus ensuring cutting accuracy and stability.

[0052] After one cut is completed, the push rod of cylinder 401 moves upward again, causing the cutter 404 to swing upward back to the initial position. At the same time, the locking plate 503 on the positioning frame 501 separates from the locking block on one side of the positioning roller 3, releasing the lock on the positioning roller 3 and preparing for the next cut operation. By repeating the above steps, the automotive foam tape can be continuously cut according to the required size and quantity.
