Description

Technical Field

[0001] This utility model relates to the technical field of product quality testing equipment, and in particular to an automatic testing equipment for straw fiber pulp molded products. Background Technology

[0002] Straw fiber pulp molded products, such as eco-friendly tableware and industrial packaging liners, are widely used in modern production due to their biodegradable and environmentally friendly properties. In large-scale production, to ensure consistent product quality, it is typically necessary to conduct quality inspections on the product's appearance and dimensions to eliminate defective products.

[0003] To improve testing efficiency and accuracy, automated testing equipment has emerged. This type of equipment typically includes a conveying mechanism, a testing mechanism, and a rejection mechanism. Products are brought into the testing mechanism by the conveying mechanism for rapid identification. Once a product is determined to be defective, the rejection mechanism (such as a cylinder pusher or air blowing device) will immediately activate, removing the defective product from the main production line and causing it to fall into a pre-set collection box.

[0004] However, existing automated inspection equipment of this type still has significant shortcomings in practical applications. On continuous high-speed production lines, the generation of defective products is constant, causing the collection bins used to collect them to fill up quickly. Once the bins are full, if not handled promptly, subsequent rejected defective products will overflow, causing chaos on-site and potentially affecting the normal operation of the equipment. Therefore, operators must pause the entire production line to manually empty or replace the collection bins before production can be restarted. This frequent downtime caused by the collection process severely restricts the overall automation level of the equipment, interrupts production continuity, and significantly reduces overall production efficiency.

[0005] Therefore, this utility model proposes an automatic testing device for straw fiber pulp molded products to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an automatic testing device for straw fiber pulp molded products, which aims to improve the existing technology where the collection box used to collect defective products must be manually emptied after the production line is stopped when it is full, resulting in low production efficiency and inconvenient disassembly and assembly of the collection box.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic testing device for straw fiber pulp molded products, comprising: a support frame, a conveyor belt, a testing area, a first collection box, a second cylinder, and a push plate; as well as a second collection box and a feeding assembly.

[0008] The feeding assembly includes a second connecting block fixed to the bracket, a track fixed on the second connecting block, a first cylinder, a fourth connecting block, and a slider fixed on the fourth connecting block, the slider being slidably connected to the track; the feeding assembly also includes a clamping plate, a first connecting rod, and a second connecting rod.

[0009] Furthermore, the second collection box is located below the first collection box; the material clamping plate is slidably connected to the bottom of the first collection box; one end of the second connecting rod is rotatably connected to the fourth connecting block; and the other end of the second connecting rod is combined with the material clamping plate by means of rotatably connecting the first connecting rod to the material clamping plate.

[0010] Preferably, the feeding assembly further includes a third connecting block, which is fixed to the second connecting block and is used to abut against the third connecting block when the material clamping plate is reset.

[0011] Preferably, the device further includes a first connecting block connected between the bracket and the first collection box, and a disassembly assembly installed in the first connecting block, the disassembly assembly being used to detachably lock the first collection box.

[0012] Preferably, the first collection box has a slot; the disassembly and assembly assembly includes a second inclined block and a locking block fixed on the second inclined block; the second inclined block is slidably installed in the first connecting block; the locking block is pluggably engaged with the slot.

[0013] Preferably, the disassembly and assembly assembly further includes a pressing block, which is slidably installed within the first connecting block.

[0014] Preferably, the disassembly assembly further includes a first inclined block, which is connected to the pressing block.

[0015] Preferably, the inclined surface of the first inclined block is in contact with the inclined surface of the second inclined block.

[0016] Preferably, the disassembly assembly further includes a spring, which is sleeved between the second inclined block and the first connecting block.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by setting a second collection box located below the first collection box, and cooperating with a feeding assembly composed of a cylinder, a linkage mechanism and a movable base plate, the problem of low production efficiency and insufficient automation caused by the need to stop the production line for manual cleaning when the non-conforming product collection box is full is solved. The technical effect of automatic transfer of non-conforming products and continuous operation without stopping the machine is achieved, which significantly improves the automation level and production efficiency of the equipment.

[0018] 2. This utility model solves the problem that the collection box is usually fixed by bolts or other means in the prior art, and the disassembly process is cumbersome, time-consuming and requires tools. It achieves the technical effect of tool-free quick disassembly and assembly of the first collection box by setting a disassembly and assembly component consisting of a pressing block, an inclined block, a spring and a locking block. This greatly simplifies the maintenance operation, shortens the cleaning and replacement time and improves the ease of operation of the equipment. Attached Figure Description

[0021] 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.

[0022] Please refer to Figures 1 to 4 This utility model provides an automatic detection device for straw fiber pulp molded products, which aims to solve the problem in the prior art that the collection box used to collect unqualified products must be manually emptied after the production line is stopped when it is full, resulting in low production efficiency and inconvenience in disassembling and assembling the collection box.

[0023] The automatic inspection equipment for straw fiber pulp molded products includes a support frame 3 serving as the overall installation base. A conveyor belt 1 for transporting the straw fiber pulp molded products is mounted on the upper part of the support frame 3. An inspection area 2 for determining product quality is located above the travel path of the conveyor belt 1. A first collection box 4 for initially collecting defective products is located on the side of the conveyor belt 1. To achieve automatic rejection of defective products, a second cylinder 8 is also installed on the support frame 3. The output end of the second cylinder 8 is connected to a push plate 9, which is located downstream of the inspection area 2. When the inspection area 2 determines a product to be defective, the second cylinder 8 actuates to drive the push plate 9 to remove the defective product. Qualified products are pushed from the conveyor belt 1 into the first collection box 4. To achieve continuous automated collection of non-qualified products and improve production efficiency, a second collection box 5 for transferring materials is provided below the first collection box 4. A feeding component 7 for controlling the automatic discharge of materials from the first collection box 4 to the second collection box 5 is connected between the first collection box 4 and the support 3. To facilitate the maintenance and replacement of the first collection box 4, a first connecting block 6 is connected between the support 3 and the first collection box 4. A disassembly and assembly component 10 is installed inside the first connecting block 6. The disassembly and assembly component 10 is used to achieve quick locking and separation between the first collection box 4 and the first connecting block 6.

[0024] The unloading assembly 7 includes a second connecting block 701 fixed on the bracket 3, and a track 703 fixed along its length on the second connecting block 701. The track 703 is a linear guide rail. The unloading assembly 7 also includes a first cylinder 702 as a power source. The first cylinder 702 is fixedly installed on the bracket 3, and a fourth connecting block 708 is fixedly connected to the output end of the first cylinder 702, i.e., the end of the piston rod. To ensure the smooth movement of the fourth connecting block 708, a slider 709 is fixedly connected to the bottom of the fourth connecting block 708. The shape and size of the slider 709 are adapted to the track 703. In the assembled state, the slider 709 slides within the track 703, so that the fourth connecting block 708 can perform stable and precise reciprocating linear motion along the track 703 under the drive of the first cylinder 702.

[0025] Meanwhile, the feeding assembly 7 also includes a clamping plate 706 for sealing or opening the bottom of the first collection box 4. One edge of the clamping plate 706 is slidably connected to the bottom of the first collection box 4 via a pivot. To convert the linear motion of the fourth connecting block 708 into the flipping motion of the clamping plate 706, the feeding assembly 7 is also provided with a first connecting rod 704 and a second connecting rod 705. One end of the second connecting rod 705 is rotatably connected to the side wall of the fourth connecting block 708 via a pin, and the other end of the second connecting rod 705 is rotatably connected to one end of the first connecting rod 704 via a pin. The other end of the first connecting rod 704 is rotatably connected to the upper surface of the clamping plate 706 via a pin. This crank-slider 709 linkage mechanism, which is composed of the first cylinder 702, the fourth connecting block 708, the second connecting rod 705, the first connecting rod 704, and the clamping plate 706, ensures that the clamping plate 706 can be smoothly flipped downward to open and upward to close under the drive of the first cylinder 702.

[0026] To ensure the reliability of the clamping plate 706 in the closed state, the feeding assembly 7 also includes a third connecting block 707 fixed to the second connecting block 701. The third connecting block 707 is positioned on the movement path of the second connecting rod 705. When the first cylinder 702 drives the fourth connecting block 708 to reset the linkage mechanism, the upper end of the second connecting rod 705 will abut against the third connecting block 707. This mechanical limiting structure ensures that the clamping plate 706 can accurately return to the closed position each time, preventing material leakage.

[0027] In a preferred embodiment, in order to achieve quick disassembly and installation of the first collection box 4, the device also includes a first connecting block 6 connected between the bracket 3 and the first collection box 4, and a disassembly and assembly component 10 installed inside the first connecting block 6. The disassembly and assembly component 10 is used to detachably lock the first collection box 4. This structure is not only stable in connection, but also convenient in operation.

[0028] As a specific implementation of the above-mentioned disassembly and assembly component 10, a locking slot 1006 is provided on the outer side wall of the first collection box 4; the disassembly and assembly component 10 includes a second inclined block 1003 and a locking block 1005 fixed on the second inclined block 1003. The second inclined block 1003 is slidably installed in a pre-set receiving cavity inside the first connecting block 6. The shape and size of the locking block 1005 are adapted to the slot 1006. In the locked state, the locking block 1005 can be plugged into the slot 1006. The first collection box 4 is reliably fixed by the engagement of the locking block 1005 and the slot 1006.

[0029] As a further preferred embodiment, in order to drive the second inclined block 1003, the disassembly and assembly assembly 10 also includes a pressing block 1001, which is slidably installed in the top opening of the first connecting block 6, so that the operator can easily perform the pressing operation from the outside.

[0030] As a refinement of the above-mentioned driving method, the disassembly and assembly assembly 10 also includes a first inclined block 1002 connected to the lower end of the pressing block 1001. The first inclined block 1002 slides synchronously with the pressing block 1001. The inclined surface of the first inclined block 1002 is in contact with the inclined surface of the second inclined block 1003. Through the interaction of the two inclined surfaces, the vertical downward movement of the pressing block 1001 can be efficiently converted into the horizontal movement of the second inclined block 1003, thereby driving the card block 1005 to disengage from the card slot 1006.

[0031] As another preferred embodiment of the above-mentioned disassembly and assembly component 10, in order to enable the disassembly and assembly component 10 to have an automatic reset function, a spring 1004 is also sleeved between the inner wall of the second inclined block 1003 and the first connecting block 6. The spring 1004 is in a pre-compressed state under normal conditions, and always provides a pushing force to the second inclined block 1003 to tend to the locking position. When the pressing force is released, the rebound force of the spring 1004 can automatically drive the second inclined block 1003 to reset, thereby driving the locking block 1005 to re-lock into the slot 1006, realizing self-locking.

[0032] Working principle: When the equipment is running, the straw fiber pulp molded products are placed on the conveyor belt 1. As the conveyor belt 1 moves, the products pass through the inspection area 2 in sequence. The inspection area 2 performs quality inspection on the products. When the inspection area 2 determines that the product is unqualified, the second cylinder 8 receives the signal and drives the push plate 9 to move, pushing the unqualified product from the conveyor belt 1 to the first collection box 4 on the side for collection. Qualified products continue to be conveyed along the conveyor belt 1 to the next process.

[0033] When the first collection box 4 is full of defective products, the first cylinder 702 of the unloading assembly 7 is activated, and the output end of the first cylinder 702 drives the fourth connecting block 708 to move. Since the slider 709 at the bottom of the fourth connecting block 708 is slidably connected to the track 703 on the second connecting block 701, the fourth connecting block 708 can smoothly drive the second connecting rod 705 to move. Since the second connecting rod 705 is rotatably connected to the first connecting rod 704 and the clamping plate 706, the linkage mechanism converts the linear motion of the fourth connecting block 708 into the downward flipping motion of the clamping plate 706, thereby opening the bottom of the first collection box 4, so that all the defective products in the first collection box 4 fall into the second collection box 5 below under the action of gravity. After the unloading is completed, the first cylinder 702 moves in the opposite direction, driving the linkage mechanism to reset, and the clamping plate 706 flips upward to close, until the second connecting rod 705 abuts against the third connecting block 707, completing one automatic unloading cycle.

[0034] When manual cleaning or replacement of the first collection box 4 is required, the operator presses the pressing block 1001 of the disassembly and assembly component 10. The pressing block 1001 slides downward in the first connecting block 6, and drives the first inclined block 1002 to slide downward simultaneously. Since the inclined surface of the first inclined block 1002 is in contact with the inclined surface of the second inclined block 1003, the downward sliding of the first inclined block 1002 forces the second inclined block 1003 to overcome the elastic force of the spring 1004 and slide horizontally in the first connecting block 6. As the second inclined block 1003 slides horizontally, the locking block 1005 fixed on the second inclined block 1003 disengages from the locking slot 1006 of the first collection box 4. At this time, the lock of the first collection box 4 is released and it can be easily removed. After releasing the pressing block 1001, the rebound force of the spring 1004 pushes the second inclined block 1003 to automatically reset, preparing for the next installation and locking.
