Description

Technical Field

[0001] This utility model relates to the field of continuous feeding and repetitive positioning technology for soft materials, specifically, to a continuous repetitive positioning processing device for soft materials. Background Technology

[0002] In modern light industry, soft materials such as rubber, foam, and flexible plastics are frequently used as substrates in production and processing. However, continuous feeding and repetitive positioning of soft materials has always been an international challenge and a research hotspot both domestically and internationally. The difficulty in continuously feeding and repetitively positioning soft materials limits the automation level of related machinery, severely impacting production efficiency. Excessive manual intervention leads to low production efficiency, unstable product quality, and high production costs.

[0003] Therefore, realizing continuous feeding and repeated positioning processing of soft materials can effectively improve the standardization and automation level of their production and processing, which is of great significance for improving production efficiency, product stability and reducing production costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a continuous and repetitive positioning processing device for soft materials, which has the advantages of high repetitive positioning accuracy, high feeding efficiency and simple structure, and is particularly suitable for continuous feeding and repetitive positioning processing of soft materials.

[0005] This utility model achieves its invention objective using the following technical solution:

[0006] A continuous repetitive positioning and processing device for soft materials, characterized in that it comprises: a worktable, an auxiliary backplate mounted on the vertical plate of the worktable, a set of working cylinders disposed on one side of the auxiliary backplate, each working cylinder being mounted on the auxiliary backplate via a cylinder fixing block, the piston rod of the working cylinder being fixedly connected to a fixture, and a cutting tool being mounted on the fixture. The fixture is fixed to the working cylinder, and the working cylinder is fixed to the auxiliary backplate via the cylinder fixing block; the fixture is fixed with a corresponding number of cutting tools, the number, shape, and length of which can be changed and adjusted. The number of fixtures is 5, and can be adjusted to be greater or less than 5 according to actual needs. The soft material moves intermittently in a unidirectional fixed distance from left to right. During the intervals of the soft material movement, the working cylinder drives the fixture and the cutting tool fixed to the fixture to move linearly, processing the soft material in the processing area.

[0007] As a further limitation of this technical solution, a clamping assembly is also included. The clamping assembly includes a fixed guide block, a support block, a vertical cylinder, and a side-mounted cylinder. The fixed guide block and the support block are fixedly connected to the vertical plate of the worktable. The vertical cylinder is fixedly connected to the vertical plate of the worktable via a cylinder fixing block. The side-mounted cylinder is fixedly connected to the support plate via a cylinder fixing plate. The support plate is fixedly connected to the cylinder fixing block. The piston rod of the vertical cylinder is fixedly connected to a movable guide block. The piston rod of the side-mounted cylinder is fixedly connected to a top block. The piston rod of the vertical cylinder is fixedly connected to the top block. The piston rod of the side-mounted cylinder is fixedly connected to the movable guide block. A guide groove is formed between the fixed guide block and the movable guide block to ensure the direction of movement of the soft material and its relative position in the processing area. When the side-mounted cylinder and the vertical cylinder work, they respectively drive the movable guide block and the top block to move, squeezing the soft substrate to ensure its relative position and reduce the amount of deformation during processing. During the intermittent operation of the soft material, the side top cylinder and the vertical cylinder work, respectively driving the top block and the movable guide block to move, squeezing the soft substrate and limiting its position and deformation.

[0008] As a further limitation of this technical solution, it also includes two feeding assemblies, one set at the front and one at the back of the processing area, to ensure that the soft substrate in the processing area maintains a constant tension, thereby ensuring its motion accuracy. Each feeding assembly includes a motor mounted on a motor mounting plate, which is fixed to one end of the worktable. Side plates are fixedly connected to both sides of the motor mounting plate, and a top plate is fixedly connected to the upper ends of the two side plates. A partition is fixedly connected to the middle of each of the two side plates. The partition and the top plate are respectively connected to a drive shaft and a transmission shaft via bearings. An extrusion wheel and a gear are fixedly connected to the drive shaft and the transmission shaft, respectively. The two gears mesh with each other. The output shaft of the motor is connected to the drive shaft via a coupling. The gear on the drive shaft meshes with the gear on the driven shaft, ensuring that the two shafts rotate synchronously in opposite directions, thereby driving the extrusion wheels on the drive shaft and the driven shaft to rotate synchronously in opposite directions, relying on the friction generated by their extrusion to move the soft material.

[0009] As a further limitation of this technical solution, the motor mounting plate is fixedly connected to the U-frame, and the U-frame has detachable bearings connecting two vertically distributed limiting wheels. This is used to limit the movement trajectory of the soft material and ensure its movement accuracy.

[0010] As a further limitation of this technical solution, the upper limiting wheel is provided with a limiting groove.

[0011] As a further limitation of this technical solution, it also includes a guide assembly, which includes two vertical guide wheels. The vertical plate of the worktable is equipped with a guide wheel support plate, and the guide wheel support plate is detachably equipped with a mounting seat connecting the two vertically distributed guide wheels.

[0012] As a further limitation of this technical solution, the vertical plate of the workbench is equipped with mounting seats for two limiting wheels that are vertically and horizontally distributed, which are used to limit the movement trajectory of soft materials and ensure their movement accuracy.

[0013] As a further limitation of this technical solution, the angle between the axis of the working cylinder and the vertical axis of the auxiliary back plate is different, and the working cylinder is symmetrically arranged with the vertical symmetry plane of the auxiliary back plate as the center.

[0014] Compared with related technologies, the continuous repetitive positioning processing device for soft materials provided by this utility model has the following beneficial effects:

[0015] (1) The fixture of this utility model is fixed with a corresponding number of cutting tools. The number, shape and length of the cutting tools can be changed and adjusted to adapt to various processing scenarios. Furthermore, the number of fixtures can be adjusted, and the soft material moves intermittently at a fixed distance. Multiple fixtures and multiple sets of cutting tools can be used simultaneously to process the soft material at the same position in the processing area, resulting in high processing efficiency and high precision.

[0016] (2) The feeding assembly of this utility model is driven by a gear mechanism, which can ensure that its transmission ratio is constant; there are two extrusion rollers for extrusion feeding, and the use of two sets of feeding assemblies before and after the processing area can ensure that the soft material in the processing area maintains constant tension, thus ensuring that the feeding position of the soft material is accurate, and the device has a simple structure and low cost.

[0017] (3) The clamping component of this utility model can clamp soft materials from the top and bottom and front and back directions in the processing area, ensuring that the deformation of the soft material during processing is stable and does not affect the processing effect, thereby ensuring processing accuracy.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] As described in the background section, achieving continuous and repetitive positioning and precise processing of soft materials can effectively improve the standardization and automation level of related production processes, which is of great significance for improving production efficiency, product stability, and reducing production costs. Therefore, this utility model proposes a continuous feeding and repetitive positioning processing device for soft materials. The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model but are not intended to limit its scope.

[0025] Example 1: A continuous repetitive positioning processing device for soft materials, comprising: a worktable 29, an auxiliary backplate 1 mounted on the vertical plate of the worktable 29, a set of working cylinders 3 arranged on one side of the auxiliary backplate 1, each working cylinder 3 being mounted on the auxiliary backplate 1 via a cylinder fixing block 2, the piston rod of the working cylinder 3 being fixedly connected to a clamp 4, and a cutting tool 5 being mounted on the clamp 4. The clamp 4 is fixed to the working cylinder 3, and the working cylinder 3 is fixed to the auxiliary backplate 1 via the cylinder fixing block 2; the clamp 4 is fixed with a corresponding number of cutting tools 5, the number, shape, and length of the cutting tools 5 can be changed and adjusted, and the number of clamps 4 is 5, which can be adjusted to be greater or less than 5 according to actual needs. The soft material moves intermittently from left to right at a fixed distance. During the intermittent movement of the soft material, the working cylinder 3 drives the fixture 4 and the cutting tool 5 fixed to the fixture to move in a straight line to process the soft material in the processing area. The distance of each movement of the soft material is fixed, so that multiple sets of cutting tools can perform different processing on the soft substrate at the same position.

[0026] The working cylinders 3 of a group have different angles with the vertical axis of the auxiliary back plate 1, and the working cylinders 3 of a group are symmetrically arranged with the vertical symmetry plane of the auxiliary back plate 1 as the center.

[0027] The workflow of this embodiment is as follows:

[0028] The working cylinder 3 extends, driving the fixture 4 and the cutting tool 5 fixed to the fixture to move in a straight line, thus processing the soft material in the processing area.

[0029] Example 2: This example further elaborates on Example 1 and includes a clamping assembly. The clamping assembly includes a fixed guide block 6, a support block 7, a vertical cylinder 13, and a side-mounting cylinder 10. The fixed guide block 6 and the support block 7 are fixedly connected to the vertical plate of the workbench 29. The vertical cylinder 13 is fixedly connected to the vertical plate of the workbench 29 via a cylinder fixing block 14. The side-mounting cylinder 10 is fixedly connected to the support plate 9 via a cylinder fixing plate 11. The support plate 9 is fixedly connected to the cylinder fixing block 14. The vertical cylinder 13... The piston rod of the side-top cylinder 10 is fixedly connected to the movable guide block 8, the piston rod of the vertical cylinder 13 is fixedly connected to the top block 12, and the piston rod of the side-top cylinder 10 is fixedly connected to the movable guide block 8. A guide groove is formed between the fixed guide block 6 and the movable guide block 8 to ensure the movement direction of the soft material and its relative position in the processing area. When the side-top cylinder 10 and the vertical cylinder 13 work, they drive the movable guide block 8 and the top block 12 to move respectively, squeezing the soft substrate to ensure its relative position and reduce the amount of deformation during processing.

[0030] The top block 12 is provided with a vertical groove, and the piston rod of the side top cylinder 10 passes through the vertical groove. When the piston rod of the vertical cylinder 13 extends or retracts, the piston rod of the side top cylinder 10 moves relative to the vertical groove, which does not hinder the top block 12 from moving in the height direction.

[0031] The workflow of this embodiment is as follows:

[0032] The side-mounted cylinder 10 and the vertical cylinder 13 operate, respectively driving the movable guide block 8 and the top block 12 to move, compressing the soft substrate, ensuring its relative position and reducing deformation during processing. The pressing assembly compresses and positions the soft substrate, facilitating processing by the processing components and ensuring processing accuracy.

[0033] Example 3: This example is a further elaboration based on Example 1 or 2, and also includes two feeding assemblies, one set at the front and one at the back of the processing area, to ensure that the soft substrate in the processing area maintains a constant tension, thereby ensuring its motion accuracy; the feeding assembly includes a motor 15, which is mounted on a motor fixing plate 16, which is fixed to one end of the worktable 29. Side plates 17 are fixedly connected to both sides of the motor fixing plate 16, and top plates 18 are fixedly connected to the upper ends of the two side plates 17. Partition plates 21 are fixedly connected to the middle parts of the two side plates 17, and the partition plates 21 and the top plates 18 are respectively connected to the drive shaft 22 and the transmission shaft 23 through bearings. The drive shaft 22 and the transmission shaft 23 are respectively fixedly connected to the extrusion wheel 19 and the gear 20, and the two gears 20 mesh with each other. The output shaft of the motor 15 is connected to the drive shaft 22 through a coupling 24. The gear 20 of the drive shaft 22 meshes with the gear 20 of the driven shaft 23, thereby ensuring that the two shafts rotate synchronously in opposite directions, thereby driving the extrusion wheels 19 on the drive shaft 22 and the driven shaft 23 to rotate synchronously in opposite directions, and relying on the friction force generated by their extrusion to drive the movement of soft materials.

[0034] The workflow of this embodiment is as follows:

[0035] The motor 15 is controlled to rotate a certain number of revolutions. The motor 15 drives the drive shaft 22 and its gear 20 to rotate through the coupling 24. The gear 20 of the drive shaft 22 meshes with the gear 20 of the driven shaft 23, thereby ensuring that the two shafts rotate synchronously in opposite directions. This drives the extrusion wheels 19 on the drive shaft 22 and the driven shaft 23 to rotate synchronously in opposite directions. The friction generated by the extrusion drives the soft material to move unidirectionally at a specific speed and rhythm, thereby realizing the intermittent movement of the soft material.

[0036] During the intermittent period of sexual material, it is squeezed and positioned by the clamping component, and processed by the processing component.

[0037] Example 4: This example further elaborates on Example 3. The motor fixing plate 16 is fixedly connected to the U-frame 26, and the U-frame 26 has detachable bearings connecting two vertically distributed limiting wheels 25. This is used to limit the movement trajectory of soft materials and ensure their movement accuracy.

[0038] The upper limiting wheel 25 is provided with a limiting groove.

[0039] The workflow of this embodiment is as follows:

[0040] When the soft material passes through the area formed by the limiting wheel 25, the movement of the soft material causes the limiting wheel 25 to rotate.

[0041] Example 5: This example is a further elaboration based on Example 3 or 4, and also includes a guide component. The guide component includes two vertical guide wheels 27. The vertical plate of the workbench 29 is equipped with a guide wheel support plate 28. The guide wheel support plate 28 is detachably equipped with a mounting seat connecting the two vertically distributed guide wheels 27.

[0042] The vertical plate of the workbench 29 is equipped with mounting seats for two limiting wheels 25 that are distributed vertically and horizontally, which are used to limit the movement trajectory of soft materials and ensure their movement accuracy.

[0043] Example 6: This example is a further elaboration based on Example 3, 4, or 5. The feeding assembly, clamping assembly, and processing assembly are uniformly controlled by a CNC system. By reasonably controlling the sequence of the side-mounted cylinder 10, the vertical cylinder 13, and the working cylinder 3, it can be ensured that the soft material is in a clamped state during each processing. After each processing is completed, the CNC system controls the feeding motor 15 to rotate, thereby driving the soft material forward by the extrusion roller 19 to advance by one distance unit, and then proceeding to the next processing, ensuring that the processing position of each set of tools is the same.

[0044] Any equivalent structural or procedural transformations made using the description and drawings of this utility model, or any direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this utility model.
