Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to a cutting equipment for producing silicone sheets. Background Art

[0002] Silicone is a common material with a wide range of applications, thanks to its excellent properties, such as flexibility, high and low temperature resistance, insulation, chemical stability, environmental protection and non-toxicity. After the silicone raw materials are mixed, molded and cured to form a continuous silicone sheet, they need to be cut into silicone strips using cutting equipment to meet the final requirements of the product. The cut silicone strips are output through a conveyor belt, and a certain distance is left between two adjacent silicone strips on the conveyor belt to avoid adhesion of silicone strips, prevent silicone strips from accumulating, and improve conveying efficiency.

[0003] However, when cutting silicone sheets, since silicone itself has a certain degree of elasticity and softness, and some types of silicone also have strong self-adhesion, the cut silicone strip may adhere to the blade during the process of the cutter lifting it off after cutting the silicone sheet, which can easily lead to discontinuous supply on the conveyor belt and affect the cutting of the next silicone strip. The operator may need to stop the machine frequently to clean the cutter, which reduces cutting efficiency and increases processing time and cost. Summary of the invention

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0022] Embodiment 1 like Figure 1 As shown, the cutting device for producing silicone sheets of the present invention comprises a workbench 10, a cutting knife 20, a conveyor belt 30 and an adsorption component.

[0023] The cutter 20 is fixedly connected to the cutter holder 210. The cutter holder 210 is disposed on the workbench 10 and is in transmission connection with the driving assembly 220. The driving assembly 220 is used to drive the cutter holder 210 to move in a vertical direction. The cutter 20 is used to cut the silicone sheet into silicone strips. In this embodiment, the driving assembly 220 is any one of an electric push rod, a hydraulic cylinder, and a pneumatic cylinder, and is mounted on the workbench 10.

[0024] The conveyor belt 30 is arranged on the workbench 10 and distributed along the length direction of the workbench 10, and is used to transport the cut silicone strips. A certain distance is left between two adjacent silicone strips on the conveyor belt 30 to prevent the silicone strips from sticking together, prevent the silicone strips from piling up, and improve the conveying efficiency. In this embodiment, the conveyor belt 30 is made of a plastic film, which is low in cost, relatively light and flexible, and will not scratch or damage the silicone strips.

[0025] like Figures 1 to 4 As shown, the adsorption component includes a first bracket 40, a second bracket 50 and a sponge 70. The first bracket 40 is fixedly connected to the knife seat 210. A first elastic member 510 is provided between the second bracket 50 and the first bracket 40. The sponge 70 is fixed to the bottom end of the second bracket 50. A plurality of adsorption members 60 uniformly distributed along the length direction of the silicone strip are provided on the second bracket 50. The adsorption member 60 extends from the second bracket 50 to the sponge 70. The adsorption member 60 includes a first cylinder 610 and a second cylinder 620. A bell mouth 630 is provided at the bottom end of the second cylinder 620. The lower bottom surface of the bell mouth 630 is flush with the lower bottom surface of the sponge 70 and is fixed, which is beneficial to improve the uniformity of the force of the adsorption component on the silicone strip, thereby improving the stability of the silicone strip when moving. The first bracket 40 is connected to the first rack 410, the first cylinder 610 is connected to the second rack 6120, and the second bracket 50 is provided with a gear 520, which meshes with the first rack 410 and the second rack 6120. In this embodiment, the first elastic member 510 is a spring, the first cylinder 610 and the second bracket 50 are connected in a limited sliding manner along the vertical direction, and because the second rack 6120 and the gear 520 remain engaged, the first cylinder 610 and the second bracket 50 can be prevented from disengaging.

[0026] When the driving assembly 220 drives the cutter 20 to descend to cut the silicone sheet, the first bracket 40 and the second bracket 50 move downward simultaneously with the knife holder 210, and the bell mouth 630 and the lower bottom surface of the sponge 70 first contact the silicone sheet, and the bell mouth 630 adsorbs the silicone sheet. As the first bracket 40 continues to move downward, the first elastic member 510 is compressed, the sponge 70 is compressed, the first bracket 40 approaches the second bracket 50, and meshes with the two racks through the gear 520, so that the first cylinder 610 moves upward relative to the second cylinder 620, thereby increasing the adsorption force of the adsorption member 60 on the silicone sheet. At the same time, the cutter 20 cuts the silicone sheet below the adsorption assembly to form a silicone strip. Subsequently, the driving assembly 220 drives the cutter 20 to rise, and the first bracket 40 rises simultaneously with the cutter holder 210. At this time, the compressed sponge 70 can be reset, giving the silicone strip a downward thrust, so that the silicone strip and the cutter 20 can move relative to each other, which is beneficial to prevent the silicone strip from sticking to the cutter. In the process of the first bracket 40 moving upward relative to the second bracket 50, the gear 520 engages with the two racks to move the first cylinder 610 downward relative to the second cylinder 620, thereby releasing the adsorption force of the adsorption member 60 on the silicone strip, pushing the silicone strip downward and making it fall on the conveyor belt 30, ensuring that the cut silicone strip can be separated from the cutter 20, preventing the silicone strip from sticking to the cutter 20, thereby ensuring the cutting efficiency and the continuous supply of the conveyor belt 30, and reducing the processing time and cost.

[0027] The first cylinder 610 is sleeved outside the second cylinder 620. The first cylinder 610 has a first air cavity 6110, and the second cylinder 620 has a second air cavity 6210 connected to the first air cavity 6110. When the second rack 6120 and the first cylinder 610 move upward relative to the second cylinder 620, the air between the bell mouth 630 and the silicone strip is discharged, so that negative pressure is formed between the bell mouth 630 and the silicone strip, and the adsorption force of the bell mouth 630 on the silicone strip is increased. When the second rack 6120 and the first cylinder 610 move downward relative to the second cylinder 620, the negative pressure between the bell mouth 630 and the silicone strip disappears, and the adsorption force of the bell mouth 630 on the silicone strip is reduced to release.

[0028] A second elastic member 4110 is provided between the first rack 410 and the first bracket 40, the second bracket 50 is provided with a limiting rod 530 extending along the length direction of the silicone strip, a third elastic member 5310 is provided between the limiting rod 530 and the second bracket 50, and the first rack 410 has a limiting notch 4120 matching the limiting rod 530. When the first bracket 40 and the first rack 410 are lowered to the limit position, the limiting rod 530 extends into the limiting notch 4120 of the first rack 410 to limit the relative position between the first rack 410 and the second bracket 50, so that when the driving component 220 drives the cutter 20 to rise, the adsorption component drives the silicone strip and the cutter 20 to be lifted up a certain distance at the same time, so that the silicone strip is separated from the conveyor belt 30, thereby preventing the silicone strip from being easily tilted relative to the width direction of the conveyor belt 30 due to unstable force and partial failure to separate from the sponge 70 or the cutter 20 in time when the silicone strip is on the continuously running conveyor belt 30; then, under the action of the second elastic member 4110, the first rack 410 passes over the limiting rod 530 and meshes with the two racks through the gear 520, so that the second rack 6120 and the first cylinder 610 move downward relative to the second cylinder 620, and the adsorption force of the adsorption member 60 on the silicone strip is released, pushing the silicone strip downward to make it fall on the conveyor belt 30. In this embodiment, the second elastic member 4110 and the third elastic member 5310 are springs.

[0029] The upper bottom surface of the first rack 410 at the limiting notch 4120 is horizontally arranged, and the lower bottom surface of the first rack 410 at the limiting notch 4120 is inclined downward from the first rack 410 to the limiting rod 530, which is conducive to ensuring that the first rack 410 can smoothly pass over the limiting rod 530.

[0030] An anti-dropout extension is provided at the top of the second cylinder 620 , and an anti-dropout ring matched with the anti-dropout extension is provided at the bottom of the first cylinder 610 to prevent the second cylinder 620 from being detached from the first cylinder 610 .

[0031] The sponge body 70 has a receiving groove 710 for receiving the bell mouth 630 . The receiving groove 710 is cylindrical and is used to provide a moving space for the bell mouth 630 and the second cylinder 620 .

[0032] Embodiment 2 like Figures 1 to 4 As shown, compared with the first embodiment, this embodiment further includes a lifting assembly, the lifting assembly includes a lifting plate 80 located below the second bracket 50, the conveyor belt 30 is placed on the lifting plate 80, magnetic parts 90 are provided at both ends of the length direction of the first bracket 40, and matching parts 810 corresponding to the magnetic parts 90 are provided at both ends of the length direction of the lifting plate 80, and the matching parts 810 are ferromagnetic.

[0033] In the first embodiment, when the silicone strip is lifted to a certain height and then put down, due to the certain distance between the silicone strip and the conveyor belt 30, the silicone strip may be tilted and misaligned when falling. For this reason, a lifting component is added in this embodiment, and the lifting plate 80 and the silicone strip are lifted and dropped simultaneously through magnetic adsorption, so that the conveyor belt 30 under the silicone strip being cut and the silicone strip are lifted and dropped simultaneously to ensure the correct arrangement of the silicone strip on the conveyor belt 30.

[0034] The magnetic member 90 includes a magnetic ball 910, which includes a first hemisphere 9110 and a second hemisphere 9120. The first hemisphere 9110 has a magnetic attraction force. The magnetic ball 910 is rotatably connected to the first bracket 40. A fourth elastic member 9130 is provided between the magnetic ball 910 and the first bracket 40, which is used to make the magnetic ball 910 have a rotation tendency of the first hemisphere 9110 toward the matching member 810. When the magnetic ball 910 rotates in the first bracket 40, the first hemisphere 9110 or the second hemisphere 9120 can face the matching member 810. When the first hemisphere 9110 faces the matching member 810, the first bracket 40 and the lifting plate 80 maintain magnetic adsorption. When the second hemisphere 9120 faces the matching member 810, the magnetic adsorption between the first bracket 40 and the lifting plate 80 is released. In this embodiment, the fourth elastic member 9130 is a scroll spring.

[0035] The magnetic member 90 further includes a push rod 920 fixedly connected to the magnetic ball 910, and the workbench 10 is provided with an extension rod 110 for pushing the push rod 920. When the first bracket 40 and the cutter 20 move downward at the same time, the first hemisphere 9110 faces the matching member 810, and then the first bracket 40 and the lifting plate 80 maintain magnetic adsorption, and are lifted away at the same time as the cutter 20, until the adsorption force of the adsorption member 60 on the silicone strip is released, and while the silicone strip falls, the extension rod 110 pushes the push rod 920 to rotate the magnetic ball 910, and the second hemisphere 9120 faces the matching member 810, and the magnetic adsorption between the first bracket 40 and the lifting plate 80 is released, and the lifting plate 80 and the conveyor belt 30 on the lifting plate 80 fall at the same time as the silicone strip.

[0036] The workbench 10 is provided with pressure wheels 120 on both sides of the conveyor belt 30 in the length direction. The pressure wheels 120 are arranged close to the lifting plate 80. The pressure wheels 120 are used to limit the conveyor belt 30 to prevent the conveyor belt 30 from rewinding.
