Description

Technical Field

[0001] This utility model relates to the field of shoe sole production technology, and in particular to a cutting device for shoe sole production. Background Technology

[0002] The sole production strip cutting device is a piece of equipment used in the sole production process to cut sole materials into specific strips. It is widely used in various shoe factories, including the production of different types of soles such as sports shoes, leather shoes, and cloth shoes. Regardless of the sole material, such as rubber soles, plastic soles, or leather soles, it can be cut and processed by the corresponding strip cutting device to meet the requirements of different styles of shoes for the shape, size, and number of sole strips.

[0003] In practical use, existing shoe sole cutting devices can cut shoe soles into strips from two directions. However, when cutting rubber soles, a large amount of debris is generated. Rubber debris is sticky and easily adheres to the blade. As the number of cuts increases, the rubber debris gradually accumulates at the blade edge, causing the blade to have increased cutting resistance, making it unable to cut into the material properly, accelerating blade wear, and causing it to become dull quickly. At the same time, these debris diffuses throughout the production workshop, seriously affecting the cleanliness of the working environment and posing a potential threat to the health of workers. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a cutting device for shoe sole production, which effectively slows down the rapid dulling process of the cutting blade, improves the durability of the cutting blade, and reduces the frequency and cost of replacing the cutting blade.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for shoe sole production, comprising a load-bearing frame, a cleaning component disposed inside the load-bearing frame, the cleaning component including a notch, the notch being formed inside the load-bearing frame, a reset elastic element fixedly connected to one side of the inner wall of the notch, a support plate fixedly connected to one side of the reset elastic element, a scraper fixedly connected to one side of the support plate, a contact block fixedly connected to one side of the support plate, a knife holder disposed on one side of the load-bearing frame, a fixing frame fixedly connected to the bottom of the knife holder, a squeezing roller disposed inside the fixing frame, a collection box fixedly connected to one side of the load-bearing frame, a negative pressure fan fixedly connected inside the collection box, a dust suction pipe fixedly connected to the bottom of the collection box, and a dust suction head fixedly connected to the bottom of the dust suction pipe.

[0006] Through the above solution, the cleaning component can automatically clean the cutting blade and the cutting area during the shoe sole cutting process, effectively ensuring the cutting effect of the cutting blade and the cleanliness of the cutting area, reducing the impact of debris on subsequent cutting operations, and improving production efficiency and product quality. When the blade holder drives the cutting blade to descend and cut, the extrusion roller extrudes the contact block, causing the scraper to retract into the notch and extrude the reset elastic element. After the cutting is completed, the blade holder rises, and the reset elastic element pushes the scraper to extend and clean up the debris, realizing an automated cleaning process.

[0007] Optionally, a mounting plate is fixedly connected to one side of the load-bearing frame, a cylinder is fixedly connected to the top of the mounting plate, a push rod is fixedly connected to the output end of the cylinder, the bottom of the push rod is fixedly connected to the top of the tool holder, a cutting blade is fixedly connected to the bottom of the tool holder, a working body is fixedly connected to the bottom of the load-bearing frame, and a cutting table is fixedly connected to the top of the working body.

[0008] The above solution utilizes a cylinder to drive the blade holder up and down, enabling precise control of the cutting stroke and force of the blade. This ensures stable and efficient cutting of shoe sole materials of different thicknesses and materials. The mounting plate is securely connected to the load-bearing frame, providing reliable support for the cylinder and blade holder system and guaranteeing the stability of the cutting process. Two symmetrically distributed high-hardness alloy steel blades allow for more uniform cutting force, improving cutting accuracy and cut quality.

[0009] Optionally, a load-bearing plate is fixedly connected to the other side of the working body, a rotary motor is fixedly connected to the top of the load-bearing plate, a first rotating roller is fixedly connected to the transmission end of the rotary motor, a first guide roller is fixedly sleeved on the side surface of the first rotating roller, a drive wheel is fixedly sleeved on the side surface of the first guide roller, a connecting belt is drivenly connected to the side surface of the drive wheel, a driven wheel is drivenly connected inside the connecting belt, the drive wheel is drivenly connected to the driven wheel through the connecting belt, a second rotating roller is fixedly connected to one side of the driven wheel, and a second guide roller is fixedly sleeved on the side surface of the second rotating roller.

[0010] Through the above scheme, the rotary motor drives the first rotating roller to rotate, and through the transmission of the driving wheel, connecting belt and driven wheel, the second rotating roller rotates synchronously, realizing the stable conveying of the shoe sole material. The first guide roller and the second guide roller not only assist in the conveying, but their surface anti-slip rubber layer can increase the friction with the shoe sole material, avoid slipping during the conveying process, ensure that the material is accurately conveyed to the cutting table for cutting, and ensure the continuity and accuracy of the cutting operation.

[0011] Optionally, a guide chute is provided on the top of the working body, and a collection chute is provided inside the working body.

[0012] Through the above scheme, the guide chute can guide the cut sole strips to slide smoothly into the collection trough by their own gravity, realizing automatic collection, reducing manual intervention, improving production efficiency, and the collection trough is used to collect sole strips in a centralized manner, which facilitates subsequent unified processing, optimizes the production process, and makes the entire sole production cutting operation smoother and more efficient.

[0013] Optionally, the scraper is made of high-hardness wear-resistant rubber, the suction pipe is made of a retractable corrugated pipe, and the suction head is horn-shaped.

[0014] Through the above solution, the scraper made of high-hardness and wear-resistant rubber can effectively remove debris from the cutter without damaging it, ensuring the cutter's service life and cutting performance. The flexible and adaptable vacuum hose can be adjusted to match the vacuum head to fully cover the cutting area. The horn-shaped vacuum head increases the suction range and suction power, allowing the negative pressure fan to efficiently collect the debris generated during cutting, keeping the work area clean and meeting environmental protection and safe production requirements.

[0015] Optionally, the mounting plate is connected to the load-bearing frame by high-strength bolts, the cutter is made of high-hardness alloy steel, and there are two cutters that are symmetrically distributed.

[0016] The above solution uses high-strength bolts to connect the mounting plate and the load-bearing frame, ensuring the stability of the entire cutting system. This allows it to withstand various forces during cylinder operation and the cutting process, preventing equipment displacement or shaking. The high-hardness alloy steel cutter has excellent wear resistance and high strength, maintaining its sharpness during frequent cutting operations and ensuring cutting quality. The two symmetrically distributed cutters make the cutting process more stable and precise.

[0017] Optionally, the first guide roller and the second guide roller are of the same size, and both the first guide roller and the second guide roller are provided with an anti-slip rubber layer on their surfaces.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] 1. This utility model, through the coordinated operation of the cleaning component, the extrusion roller and the contact block, allows the scraper to clean the sticky rubber debris adhering to the cutter after the cutter completes the cutting action. This prevents the rubber debris from gradually accumulating at the cutter edge, thereby reducing cutting resistance, effectively slowing down the rapid dulling process of the cutter, improving the durability of the cutter, and reducing the frequency and cost of replacing the cutter.

[0020] 2. When the device is working, the negative pressure fan is always running. Together with the dust suction pipe and dust suction head, it can suck the debris generated by cutting and the debris cleaned off the cutter into the collection box, which greatly reduces the spread of debris in the production workshop, keeps the working environment clean, and reduces the potential impact on the health of the staff.

A guide chute 18 is provided on the top of the working body 7. A collection chute 19 is provided inside the working body 7.

[0032] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6The scraper 204 is made of high-hardness wear-resistant rubber, the suction pipe 211 is made of telescopic corrugated pipe, the suction head 212 is shaped like a trumpet, the mounting plate 3 is connected to the load-bearing frame 1 by high-strength bolts, the cutter 6 is made of high-hardness alloy steel, there are two cutters 6 and they are symmetrically distributed. The mounting plate 3 is connected to the load-bearing frame 1 by high-strength bolts, the cutter 6 is made of high-hardness alloy steel, there are two cutters 6 and they are symmetrically distributed.

[0033] Further explanation is needed: When the blade holder 206 moves downwards to cut, the pressure roller 208 presses against the contact block 205, thereby triggering the action of the cleaning component 2. The scraper 204 is made of high-hardness, wear-resistant rubber. This material selection is crucial. The rubber material has a certain degree of flexibility, which allows it to closely conform to the surface of the cutter 6, effectively cleaning the adhering rubber debris without damaging the cutter 6. The high hardness ensures that the scraper 204 is not easily deformed or worn during long-term, frequent cleaning operations, extending its service life. The reset elastic element 202 is usually a spring. After being compressed and deformed, it can quickly release energy when the pressure disappears, pushing the support plate 203 and the scraper 204 to reset, realizing the automatic cleaning function and greatly improving the automation level and production efficiency of the equipment.

[0034] The working principle of the above embodiment is as follows: The shoe sole material to be cut is placed between the first rotating roller 11 and the second rotating roller 16. The rotary motor 10 is started, and its transmission end drives the first rotating roller 11 to rotate. Since the first guide roller 12, which is fixedly sleeved on the side surface of the first rotating roller 11, is fitted with a drive wheel 13, and the drive wheel 13 is connected to the driven wheel 15 through the connecting belt 14, and the driven wheel 15 is fixed on one side of the second rotating roller 16, the second rotating roller 16 rotates synchronously when the first rotating roller 11 rotates. In addition, the surfaces of the first guide roller 12 and the second guide roller 17 are both provided with anti-slip rubber layers, which can ensure that the shoe sole material moves forward stably during the conveying process without slipping. The material is smoothly conveyed to the top of the cutting table 8.

[0035] Next, when the sole material is delivered to the designated position, cylinder 4 is activated. The output end of cylinder 4 pushes the push rod 5, causing the blade holder 206 to move downward. Simultaneously, the extrusion roller 208 on the inner side of the bottom fixed frame 207 of the blade holder 206 descends, extruding the contact block 205. The contact block 205 is connected to the support plate 203. After being extruded, the support plate 203 drives the scraper 204 to move into the notch 201, extruding the reset elastic element 202 to deform and store energy. At the same time, two symmetrically distributed cutters 6 made of high-hardness alloy steel, fixed at the bottom of the blade holder 206, cut the sole material. After the cutting action is completed, cylinder 4 drives the blade holder 206 to move upward. The extrusion pressure of the extrusion roller 208 on the contact block 205 disappears. At this time, the reset elastic element 202 releases the stored elastic potential energy, pushing the support plate 203 and the scraper 204 to move out of the notch 201. The scraper 204, made of high-hardness wear-resistant rubber, cleans the rubber debris adhering to the cutter 6.

[0036] Finally, when the device is working, the negative pressure fan 210 is always running. The bottom of the collection box 209 is fixedly connected to the funnel-shaped suction head 212 through the retractable corrugated suction pipe 211. The dust generated during cutting and the dust cleaned off the cutter 6 are sucked into the collection box 209 to further clean the working area. After the shoe sole strips are cut, they slide down the guide chute 18 into the collection trough 19 for easy collection and subsequent processing.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
