Description

Technical Field

[0001] This application relates to the field of adhesive strip cutting technology, and in particular to a simulated involute slicing machine. Background Technology

[0002] In the tire manufacturing industry, rubber sheet cutting is undoubtedly a crucial process, directly affecting the overall quality, performance, and production efficiency of the tire. The tire production process is a complex and sophisticated system engineering project, mainly comprising six closely linked and indispensable major processes: mixing, rubber component preparation, molding, vulcanization, final inspection, and tire testing. Each step is closely interconnected, working together to ensure the high-quality transformation of tires from raw materials to finished products. The mixed rubber material is further processed into the various components required for the tire, such as the tread, sidewall, and ply. Among the rubber component preparation processes, the ply cutting stage is of paramount importance. As the tire's skeleton material, the precision and efficiency of its cutting directly affect the tire's structural strength and safety. Therefore, this stage requires specialized cutting equipment to precisely cut the rubber sheet to ensure that the size, shape, and position of the ply meet design requirements.

[0003] Currently, most rubber sheet cutting devices widely used in the tire manufacturing industry rely on direct compression between the blade and the anvil to achieve the cutting function. Although this traditional cutting method can meet basic production needs to a certain extent, it generates huge extrusion and friction forces between the blade and the anvil during the cutting process. This high-intensity physical action not only accelerates the wear of the blade and shortens its service life, but also prevents incomplete cutting (i.e., the rubber sheet is not completely broken) due to material hardness, blade wear, or improper cutting parameter settings. Traditional cutting devices often cannot detect this situation in real time, and therefore cannot take timely measures to maintain or replace the blade based on the detection results. Summary of the Invention

[0004] This device provides a simulated involute slicer, the specific implementation of which is as follows:

[0005] An involute slicer, comprising:

[0006] The ring-shaped cutter holder and the anvil tube have a rubber sheet conveying and cutting channel between them, and a gear structure meshes between the sides of the ring-shaped cutter holder and the anvil tube.

[0007] The ring-shaped blade holder has several cutters evenly spaced along its circumference, and the anvil cylinder has several grooves around its circumference that engage with the ends of the cutters. The cutting effect of the rubber sheet is improved by the tearing of the grooves and the squeezing of the back of the cutter.

[0008] A proximity switch is coaxially arranged with the annular cutter holder. The output end of the proximity switch is connected to a telescopic sleeve. The annular cutter holder has wedge-shaped notches at the installation position of the cutter. Each wedge-shaped notch is slidably connected to a detection element. A spring is installed at the sliding part, and the end of each detection element protrudes from the side of the annular cutter holder and abuts against the telescopic sleeve. When any detection element presses against the uncut rubber sheet, it axially triggers the proximity switch to respond.

[0009] Preferably, a driven gear is coaxially provided on the side of the annular tool holder, and a driving gear that meshes with the driven gear is coaxially provided on the side of the anvil cylinder.

[0010] Based on the above technical solutions, the linear speed synchronization of the driven gear and the driving gear ensures that the annular cutter holder and the anvil cylinder can rotate smoothly and synchronously. During the film cutting process, a specific overlap distance is designed between the cutter and the anvil cylinder. When the cutter and the anvil cylinder meet in this overlap area, they work together on the film to ensure that the cutting action is both fast and accurate. The overlap design can effectively reduce the wear and damage to the cutter while cutting the film, thereby extending the service life of the cutter.

[0011] Preferably, it also includes a connecting seat for mounting the cutter, the connecting seat having a fixing rod extending vertically, the fixing rod passing through the cutter, and its end being threaded with an upper bolt.

[0012] Based on the above technical solution, by adding a connecting seat between the cutter and the ring cutter holder, the installation process of the cutter and the adjustment of the cutter position are completely independent of each other, which greatly improves the flexibility and convenience of operation. In actual use, the cutter can be firmly installed on the connecting seat, and the connecting seat is tightly fitted with the ring cutter holder to ensure the stability and reliability of the cutter under high-speed operation. The independent adjustment mechanism allows the operator to make precise fine adjustments to the cutter position according to specific needs without reinstalling the cutter.

[0013] Preferably, the annular cutter holder has a mounting groove at the wedge-shaped notch, the connecting seat is laterally slidably connected to the mounting groove, and the connecting seat is threaded to the annular cutter holder by a lower bolt.

[0014] Preferably, an adjustment hole is provided on the mounting groove, the other end of the fixing rod is slidably connected to the adjustment hole, and the protruding part of the fixing rod is threaded with a lower bolt.

[0015] Based on the above technical solution, the combination of upper and lower bolts achieves a stable installation of the cutter on the connecting seat and flexible adjustment of its extension length relative to the annular cutter holder. The upper bolt is responsible for fixing the cutter to the connecting seat, ensuring its stability and safety during high-speed operation. The lower bolt plays an adjusting role; by adjusting its tightness, the extension length of the cutter and the connecting seat relative to the annular cutter holder can be precisely controlled, thereby meeting the needs of different cutting tasks. The upper and lower bolts share the same fixing rod, which not only simplifies the assembly process but also significantly saves assembly space, making the entire cutter assembly more compact and efficient.

[0016] Preferably, the detection component includes a lever and a wedge-shaped slider formed by connecting blocks, and the three components together form an L-shape.

[0017] Preferably, the driven gear has a sliding groove, the connecting block is slidably connected to the sliding groove, and the spring is located in the sliding groove.

[0018] Preferably, the wedge-shaped slider has an inclined surface on the side facing the telescopic sleeve.

[0019] Based on the above technical solution, multiple detection components are deployed on the annular cutter holder. These detection components correspond one-to-one with the cutter, forming a highly efficient and reliable monitoring system. When the rubber sheet fails to be cut smoothly by the cutter, any corresponding detection component detects this abnormality and quickly triggers the same proximity switch for an immediate response, greatly improving the intelligence level and fault response speed of the equipment.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. This utility model, by imitating a hammer-operated rubber cutter, ensures that there is an overlap distance between the cutter and the anvil cylinder, thereby reducing damage to the cutter when cutting the rubber sheet;

[0022] 2. In this utility model, an additional connecting seat is provided in addition to the cutter, so that the installation structure of the cutter and the subsequent adjustment structure are separated. The cutter is installed on the connecting seat by the upper bolt, and the extension length of the cutter and the connecting seat relative to the ring cutter seat is adjusted by the lower bolt. Moreover, the upper and lower bolts share the same fixing rod, which further saves assembly space.

[0023] 3. This utility model has a simple structure. By adding multiple detection elements to the annular cutter holder, each detection element corresponds to one cutter. When the rubber sheet is not cut by the cutter, the same proximity switch can be triggered by any detection element to respond. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a simulated involute slicer.

[0038] Example 1

[0039] Reference Figures 1 to 6 This embodiment discloses a simulated involute slicing machine, including a connecting seat 9, an annular blade holder 1, and a blade anvil tube 6, with a conveying and cutting channel for a rubber sheet 10 between them. The annular blade holder 1 is coaxially provided with a driven gear 12 on its side, and the blade anvil tube 6 is coaxially provided with a driving gear 5 that meshes with the driven gear 12 on its side. The annular blade holder 1 is provided with a plurality of cutting blades 3 at equal intervals along its circumference, and the blade anvil tube 6 is provided with a plurality of blade grooves 601 that engage with the ends of the cutting blades 3. The cutting effect of the rubber sheet 10 is improved by the tearing of the blade grooves 601 and the squeezing of the back of the cutting blades 3.

[0040] Bolt component 7 includes an upper bolt 701 and a lower bolt 702. A fixing rod 901 extends vertically from the connecting seat 9, passing through the cutter 3, and its end is threaded with the upper bolt 701. An installation groove 101 is provided at the wedge-shaped notch of the annular cutter holder 1. The connecting seat 9 is laterally slidably connected to the installation groove 101, and the connecting seat 9 is threaded to the annular cutter holder 1 via the lower bolt 702. An adjustment hole 102 is provided on the installation groove 101, and the other end of the fixing rod 901 is slidably connected to the adjustment hole 102, with the protruding part of the fixing rod 901 threaded with the lower bolt 702.

[0041] The specific implementation process is as follows: When assembling the cutter 3, the cutter 3 is inserted into the fixing rod 901 of the connecting seat 9, and the upper bolt 701 is rotated to fix it; when adjusting the distance of the cutter 3, the connecting seat 9 is slid to the appropriate position, and the fixing rod 901 slides relative to the adjusting hole 102, and then the lower bolt 702 is rotated to position the connecting seat 9; the drive gear 5 is connected to an external motor, and the motor drives the drive gear 5 and the driven gear 12 to rotate, thereby causing the annular cutter holder 1 and the anvil cylinder 6 to rotate. When cutting the rubber sheet 10, the cutter 3 inserts its end into the cutter groove 601, and the back of the cutter 3 is used to squeeze and peel the cutting part 1001 from the part to be cut 1002.

[0042] Example 2

[0043] Reference Figures 2 to 4 Based on the above embodiments, this embodiment also discloses an involute slicer, which further includes a proximity switch 11 coaxially arranged with the annular cutter holder 1. The output end of the proximity switch 11 is connected to a telescopic sleeve 8. The annular cutter holder 1 is provided with a wedge-shaped notch at the mounting position of the cutter 3. Each wedge-shaped notch is slidably connected to a detection element 2. A spring 4 is installed at the sliding position. The end of each detection element 2 passes through the side of the annular cutter holder 1 and abuts against the telescopic sleeve 8. After any detection element 2 presses against the uncut rubber sheet 10, the proximity switch 11 is axially triggered to respond.

[0044] The detection component 2 includes a lever 201 and a wedge slider 203 connected by a connecting block 202. The three components are in an L-shape. A sliding groove is provided on the driven gear 12. The connecting block 202 is slidably connected to the sliding groove, and the spring 4 is located in the sliding groove. In this structure, the wedge slider 203 is inclined on the side facing the telescopic sleeve 8.

[0045] The specific implementation process is as follows: when the cutting part 1001 is not detached from the part to be cut 1002, the annular knife holder 1 continues to rotate, and the lever 201 touches the cutting part 1001 that has not been detached, causing the lever 201 to move, thereby changing the contact area between the wedge slider 203 and the telescopic sleeve 8, thereby triggering the proximity switch 11; after the proximity switch 11 is triggered, the motor is turned off, and manual cutting is performed.

[0046] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
