Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to the discharge mechanism of a feeding machine. Background Technology

[0002] The cutting machine is a key piece of equipment in material processing, its main function being to saw raw materials according to preset dimensions. In actual production, due to irregular shapes, dimensional deviations, or material defects at the initial and final ends of the raw materials, sawing often produces waste material that does not meet the required dimensions. Existing cutting machines typically discharge all sawn materials (including qualified products and waste) into a hopper through the same outlet, requiring subsequent manual or auxiliary equipment for secondary screening to separate qualified products from waste.

[0003] This centralized discharge method has obvious drawbacks: First, it increases the workload of subsequent screening, leading to reduced production efficiency and increased labor costs; second, after waste is mixed with qualified products, the surface quality of qualified products may be damaged due to collisions during handling or stacking; in addition, if waste is not separated in time and mixed into subsequent processing steps (such as assembly, finishing, etc.), it may cause equipment failure, a decrease in product qualification rate, or even production line shutdown.

[0004] Therefore, how to reduce the workload of screening and ensure product quality is an urgent technical problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a discharge mechanism for a feeding machine to solve the problems existing in the prior art. By using a drive assembly to drive the guide plate to switch between the first working position and the second working position, qualified products and waste products in the sawn material are separated and placed into qualified product bins and waste product bins respectively. This realizes the screening of sawn material at the discharge port, reducing the workload of subsequent screening and reducing the adverse effects caused by waste products being mixed with qualified products.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a discharge mechanism for a feeding machine, including a guide plate and a drive assembly. The inlet of the guide plate is used to receive sawn material, and the outlet of the guide plate is used to guide a material box, which includes a qualified product box and a waste product box. The drive assembly is connected to the guide plate and is used to change the working position of the guide plate. The working position includes a first working position and a second working position. In the first working position, the outlet of the guide plate faces the qualified product box, and in the second working position, the outlet of the guide plate faces the waste product box.

[0007] In one embodiment, the guide plate includes a bottom plate and two side plates, with the two side plates disposed on both sides of the bottom plate, and the bottom plate and the two side plates forming a discharge channel.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide a discharge mechanism for a feeding machine to solve the problems existing in the prior art. By using a drive component to drive the guide plate to switch between the first working position and the second working position, qualified products and waste products in the sawn material are separated and placed into qualified product bins and waste product bins respectively. This realizes the screening of sawn material at the discharge port, reducing the workload of subsequent screening and reducing the adverse effects caused by waste products being mixed with qualified products.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a discharge mechanism for a cutting machine, including a guide plate 30 and a drive assembly 33. The guide plate 30 can be in a non-powered mode and a powered mode. In the former, it can be inclined downwards at a certain angle, allowing the sawn material to slide downwards into the hopper under its own weight after being placed on the guide plate 30. In the latter, it is not limited to an inclined state; it can also be horizontal or lifted, relying on conveying power for transport. Regardless of the mode, the function of the guide plate 30 is to transport the sawn material to a designated position. The inlet of the guide plate 30 is connected to the discharge port of the cutting machine to receive the sawn material, and the outlet of the guide plate 30 guides the sawn material to the hopper. The hopper includes a qualified product hopper and a waste product hopper, distinguished according to whether the product is qualified or waste. The drive assembly 33 is connected to the guide plate 30. The drive assembly 33 is used to change the working position of the guide plate 30, which includes a first working position and a second working position. In the first working position, the outlet of the guide plate 30 faces the qualified product bin, and qualified products enter the qualified product bin through the conveying and guiding action of the guide plate 30. In the second working position, the outlet of the guide plate 30 faces the scrap bin, and scrap products enter the scrap bin through the conveying and guiding action of the guide plate 30. The drive assembly 33 can adopt a cam mechanism, that is, a cam-driven and spring-returned method to change the orientation of the guide plate 30 to change the working position. It can also adopt a gear mechanism, that is, a gear meshing rotation drive method to change the orientation of the guide plate 30 to change the working position. Of course, other feasible drive methods can also be used, which will not be described in detail here.

[0023] This utility model utilizes the drive assembly 33 to drive the guide plate 30 to switch between the first working position and the second working position, so that when the guide plate 30 receives sawn material, it can transport different sawn materials to different bins, that is, to distinguish between qualified and waste products in the sawn material and place them into qualified product bins and waste product bins respectively. This realizes the screening of sawn material at the discharge port, reducing the workload of subsequent screening and reducing the adverse effects caused by waste products being mixed with qualified products.

[0024] In one embodiment, combined with Figure 3 As shown, the guide plate 30 includes a base plate 31 and two side plates 32. The side plates 32 are disposed on both sides of the base plate 31. The base plate 31 and the side plates 32 form a discharge channel. The base plate 31 mainly supports the sawn material, while the side plates 32 define the conveying direction, allowing the sawn material to move along the discharge channel and be conveyed to different material bins. The base plate 31 can use sliding friction or rolling friction. When using sliding friction, a smooth flat plate or a perforated flat plate can be used. A perforated flat plate can better remove dust or debris. When using rolling friction, a rolling structure with rollers or drums can be used to reduce friction. The side plates 32 can be a separate structure, each independently connected to the base plate 31, or they can be an integrally connected structure. There is a hollow connecting plate between the side plates 32. The connecting plate is used to expose the base plate 31 in the hollow part, so that the side plates 32 can be installed and fixed at the same time, while the base plate 31 serves as the main load-bearing structure and allows dust or debris to be discharged downward when the base plate 31 has openings.

[0025] In one embodiment, combined with Figures 3-5 As shown, the base plate 31 includes a support member and a sliding perforated member. The sliding perforated member is connected to the support member and is used to support the sawn material. The sliding perforated member has openings for debris to fall through. When the sawn material slides on the sliding perforated member, debris or dust will fall through the openings, thereby improving the cleanliness of the sawn material. The support member supports the sliding perforated member, ensuring it has a suitable angle and also cooperating with the drive assembly 33 to adjust the conveying direction of the sliding perforated member. The sliding perforated member can be a perforated plate structure, with the perforations forming the openings; it can also be a grid structure, with the grid gaps forming the openings; other methods can also be used to form the openings, which will not be elaborated here.

[0026] In one implementation, such as Figure 4As shown, the support member includes an upper base plate 312, a lower base plate 314, and a middle plate 313. The upper base plate 312 and the lower base plate 314 are connected by the middle plate 313, and the upper base plate 312, the middle plate 313, and the lower base plate 314 are combined to form an I-shaped structure. In this example, the side plate 32 is connected by the middle plate 313, which covers the I-shaped support member and is connected to the upper base plate 312 and the lower base plate 314 of the support member by screws. In this example, the upper base plate 312 and the middle plate 313 are installed face to face, and the lower base plate 314 and the middle plate 313 are installed face to face. Thus, both the upper base plate 312 and the lower base plate 314 are higher than the plane of the middle plate 313. After connecting the sliding cutout part, there is a gap between the sliding cutout part and the middle plate 313. The setting of this gap allows the holes on the sliding cutout part to have a communication channel with the space below without being blocked. That is, on the basis that the support can stably support the sliding cutout part, it can also avoid obstructing the cleaning of dust or debris.

[0027] In one implementation, such as Figure 3 and Figure 4 As shown, the sliding hollow component includes multiple support rollers 311. The upper base plate 312 is provided with a first groove 3121, and the lower base plate 314 is provided with a second groove 3141. The first groove 3121 and the second groove 3141 are provided one-to-one to form multiple sets of installation spaces. The installation spaces are used for the support rollers 311 to be embedded. After being embedded, the support rollers 311 are axially limited by the first groove 3121 and the second groove 3141 at both ends, so that the support rollers 311 maintain the installation position. In addition, the support rollers 311 can rotate within the installation space or remain fixed. There are gaps between adjacent support rollers 311. In this example, the axial direction of the support roller 311 is parallel to the conveying direction of the sawn material, and the outer diameter side of the support roller 311 protrudes from the remaining surface of the sliding perforated part. In other words, the support roller 311 can form a line support for the sawn material, thereby further reducing the contact area with the sawn material and further reducing the friction. At the same time, dust and debris can slide down along the arc-shaped surface of the support roller 311, improving cleaning ability while ensuring stable support (compared to directly using thin rod support).

[0028] In one implementation, such as Figure 4As shown, the upper base plate 312 is provided with a scissor edge 3122, which is located in the swing direction of the support member. This scissor edge 3122 creates clearance space when the support member swings, preventing interference between the upper base plate 312 and the frame 6, and ensuring smooth deflection of the support member under the action of the drive assembly 33. It should be noted that the support member can deflect in either a forward or unilateral direction; the forward direction is the first working position, and the unilateral direction is the second working position. In this case, the scissor edge 3122 is located on one side of the upper base plate 312, while the drive assembly 33 is located on the opposite side. This arrangement facilitates structural layout and meets the needs of different working positions. Furthermore, the scissor edge 3122 can be provided on both sides of the upper base plate 312. When the support member deflects, it can also have a third working position. In this case, the third working position is located on the same side as the drive assembly 33, and the third working position can be used to place qualified or defective products.

[0029] In one embodiment, combined with Figures 3-5 As shown, the drive assembly 33 includes a telescopic cylinder 331, a first support 332, and a second support 333. The fixed end of the telescopic cylinder 331 is hinged to the first support 332, and the movable end of the telescopic cylinder 331 is hinged to the second support 333. The first support 332 is mounted on the frame 6, and the second support 333 is connected to a support member, which is hinged to the frame 6. The telescopic cylinder 331 can be in the form of a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod. The telescopic cylinder 331, the support member (or an additional connecting structure, such as a hinge 37), and the frame 6 form a movable triangular structure. When the telescopic cylinder 331 extends in the positive direction, the triangular structure deforms, and the support member drives the entire guide plate 30 to deflect to one side. When the telescopic cylinder 331 returns to its original position, the support member drives the entire guide plate 30 to return to its original position. When the telescopic cylinder 331 retracts in the negative direction, the support member drives the entire guide plate 30 to deflect to the other side. At this time, the guide plate 30 can have a third conveying direction.

[0030] In one embodiment, combined with Figures 3-5 As shown, it also includes a hinge 37 and a third support 38. The hinge 37 includes a hinge part and an inclined part that are connected to each other. The hinge part is hinged to the third support 38 through a vertical shaft, so that the hinge part can swing left and right in the horizontal direction. The third support 38 is mounted on the frame 6, that is, the hinge 37 can swing left and right in the horizontal direction on the frame 6. The inclined part is used to connect the middle plate 313 of the support member. When the hinge 37 swings horizontally, the support member is always kept in an inclined state, which makes it easy for the sawn material to slide down to different material boxes.

[0031] In one embodiment, combined with Figures 2-5As shown, it also includes a dust collection trough 34, located below the sliding perforated part. When the sawn material passes through the sliding perforated part, the sawing debris or dust generated will fall into the dust collection trough 34 below under the action of gravity through the gaps in the movable perforated part. The dust collection trough 34 collects the dust or debris, improving the cleanliness of the sawn material and reducing the impact on the working environment. In this example, the dust collection trough 34 has a large opening at the top and gradually narrows at the bottom. A negative pressure dust collection device is connected to the bottom of the dust collection trough 34. The negative pressure dust collection device generates negative pressure suction. When the sawn material passes through the sliding perforated part, the dust or debris will enter the dust collection trough 34 under the action of negative pressure suction, further improving the cleaning ability of dust or debris.

[0032] In one embodiment, combined with Figures 2-5 As shown, it also includes a discharge platform 35 and a clamping plate 36. The discharge platform 35 is located in front of the guide plate 30 (i.e., in the material inlet direction) and is used to support the profile to be sawed. The discharge platform 35 has a sawing kerf for the saw blade 5 to enter and exit. That is, when the saw blade 5 moves in and out of the sawing kerf, it will cut the profile to obtain the required length of sawn material. The saw blade 5 is connected to a drive motor or other rotary drive device. The saw blade 5 and the rotary drive device form a saw head, which reciprocates under the action of the rotary drive device. The clamping plate 36 is located above the discharge platform 35 and on the side of the sawing kerf away from the guide plate 30. The clamping plate 36 can clamp the profile to be sawed during sawing to ensure stability, sawing accuracy and safety during the sawing process. The clamping plate 36 is connected to a vertical moving drive device, which can drive the clamping plate 36 to move up and down.

[0033] This utility model also provides a feeding device, which includes the discharge mechanism 3 described above, as well as a housing 1, a control panel 2, and an electrical cabinet 4. The discharge mechanism 3 is installed at the discharge port and connected to the frame 6. The housing 1 covers the outside of the frame 6, mainly for protection. The control panel 2 is also installed on the housing 1, on which programs and parameters can be adjusted and set. The electrical cabinet 4 is located on the side or rear of the housing 1, providing the power required by the feeding device. A saw head is also installed inside the housing 1, which drives the saw blade 5 to move and achieve cutting. A feeding structure and a loading structure are also installed on the side of the housing 1 away from the discharge mechanism 3 to complete the entire feeding process.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
