Description

Technical Field

[0001] This utility model relates to the field of natural rubber processing technology, and in particular to an automatic feeding device for a round tube rubber hanging rack. Background Technology

[0002] Smoked sheet rubber is a natural rubber commodity, and its current production process is as follows:

[0003] (1) Collection and processing of latex: Collect fresh natural rubber latex, purify it, and remove impurities;

[0004] (2) Coagulation: After filtering out impurities, the latex is diluted with water and then acid is added for coagulation treatment, so that the latex coagulates into a block.

[0005] (3) Slicing and tableting process: After the solidified rubber block is cut into sheets, it is then pressed into thin sheets by a tablet press to facilitate subsequent fumigation treatment;

[0006] (4) Smoking and drying: The compressed film is smoked and dried. This step is a key step in the production of smoked sheet adhesive. Smoking not only gives the film a unique smoky odor, but also improves its anti-aging and anti-corrosion properties.

[0007] (5) Packaging: The smoked and dried sheet adhesive will be packaged.

[0008] In the smoking and drying process, the cut film needs to be supported by a hanging rack for moisture control and drying before smoking. The hanging rack is usually made of round wooden tubing, and currently, hanging the film on the rack is mostly done manually. Based on this, Chinese Patent Application No. 2024115707038 discloses a smoked sheet adhesive production system and process, which includes a film hanging rod device connected to a pressing mechanism via a conveyor belt. This device enables automatic cutting, hanging, and unloading of the incoming material (continuous sheets). The automatic hanging rack device also loads the rods full of film sheets onto the rack for subsequent drying.

[0009] In the aforementioned existing technologies, while the automatic feeding of hanging rods can meet the requirements for batch storage of hanging rods, the feeding process still requires continuous manual supply of hanging rods. Utility Model Content

[0010] The purpose of this invention is to solve the problem in the existing technology that the hanging rod is difficult to store and automatically feed in the production of smoked sheet adhesive.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] An automatic feeding device for a round tube adhesive rack includes a frame, a feeding rack on the frame, a lifting device on the output end of the feeding rack, an ejection device on one side of the lifting device, a first material rack on the feeding rack located inside the frame, a second material rack above the first material rack, and a third material rack above the second material rack. The first material rack, the second material rack, and the third material rack are arranged in a "Z" shape inside the frame, and a blocking device is provided between the first material rack and the second material rack.

[0013] Preferably, the blocking device includes a motor located on the frame, a rotating shaft on the output shaft of the motor, the rotating shaft being connected to the frame, and a cam on the rotating shaft.

[0014] Preferably, the lifting device includes a lifting cylinder located on the frame, a lifting plate is provided on the piston rod of the lifting cylinder, and a plurality of guide rods are provided at the bottom of the lifting plate, the guide rods sliding relative to the frame.

[0015] Preferably, the ejection device includes an ejection trough located on the frame, a plurality of support shafts are provided in the ejection trough, rollers are provided on the support shafts, an ejection cylinder is provided above the ejection trough, and an ejection plate is provided on the sliding block of the ejection cylinder.

[0016] Preferably, the outflow groove is provided with a plurality of mounting grooves, the support shaft is engaged with the mounting grooves, the support shaft is provided with a nut, and the nut is threadedly connected to the support shaft.

[0017] Preferably, both the lifting cylinder and the ejection cylinder are connected to an external high-pressure air source, and the lifting cylinder, the ejection cylinder, and the motor are all electrically connected to an external control signal.

[0018] The beneficial effects proposed by this utility model are as follows:

[0019] The round tubes, acting as adhesive holders, are sequentially added to the feeding rack. During this process, the round tubes pass through the third rack, the second rack, and the first rack. When the round tubes move to the lifting device via the first rack, the lifting device raises them into the ejection device, which then outputs the round tubes to the production line. The combination of the first, second, and third racks increases the storage space of the feeding rack and improves the equipment's continuous operation capability. In the above process, the blocking device is used for discharging from the second rack. When the first rack is low on material, the blocking device closes, allowing unobstructed discharge from the second rack, enabling the round tubes to enter the first rack. When the first rack is full of round tubes, the blocking device activates, sealing the outlet of the second rack, preventing the round tubes in the second rack from compressing the round tubes in the first rack. This blocking device reduces the risk of the lifting device being obstructed when material is squeezed in the first rack. The above-mentioned process automates the rubber coating process in the pre-processing of natural rubber using automated equipment, thereby improving production efficiency and reducing labor costs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1 to 7 An automatic feeding device for a round tube adhesive hanger includes a frame 1, a feeding rack on the frame 1, a lifting device on the output end of the feeding rack, and an ejection device on one side of the lifting device. A first material rack 2 is located within the frame 1, a second material rack 3 is located above the first material rack 2, and a third material rack 4 is located above the second material rack 3. The first material rack 2, the second material rack 3, and the third material rack 4 are arranged in a "Z" shape within the frame 1, and a blocking device is provided between the first material rack 2 and the second material rack 3. Specifically, round tubes, serving as adhesive hangers, are sequentially added to the feeding rack. During this process, the round tubes pass through the third material rack 4, the second material rack 3, and the first material rack 2. When the round tubes move to the lifting device via the first material rack 2, the lifting device lifts the round tubes into the ejection device. Subsequently, the ejection device is activated, outputting the round tubes to the production line. The combination of the first material rack 2, the second material rack 3, and the third material rack 4 increases the storage space of the feeding rack and improves the continuous operation capability of the equipment. During the above process, the blocking device is used for the discharge of the second material rack 3. When the first material rack 2 is short of material, the blocking device closes, allowing the discharge of the second material rack 3 to be unobstructed, and the round tubes can enter the first material rack 2 through the second material rack 3. When the first material rack 2 is full of round tubes, the blocking device activates, blocking the discharge port of the second material rack 3, preventing the round tubes of the second material rack 3 from squeezing the round tubes in the first material rack 2. The blocking device reduces the risk of obstructing the operation of the lifting device when material is squeezed in the first material rack 2. This achieves automated operation of the rubber coating process in natural rubber pre-processing through automated equipment, improving production efficiency and reducing labor costs.

[0030] Specifically, the blocking device includes a motor 5 located on the frame 1. A rotating shaft 6 is mounted on the output shaft of the motor 5 and connected to the frame 1. A cam 7 is mounted on the rotating shaft 6. When the blocking device is activated, the output shaft of the motor 5 rotates, causing the rotating shaft 6 to rotate, which in turn causes the cam 7 to rotate. The cam 7 rotates to a position higher than the discharge end of the second material rack 3. Then, the motor 5 stops, causing the cam 7 to stop rotating. At this time, the cam 7 can limit the rotation of the round tube within the second material rack 3. Conversely, when it is necessary to output the round tube from the second material rack 3, the output shaft of the motor 5 rotates, causing the rotating shaft 6 to drive the cam 7 to rotate. The cam 7 rotates to a position lower than the discharge end of the second material rack 3. At this time, the cam 7 releases the limitation on the round tube within the second material rack 3, allowing the round tube to pass through the second material rack 3 and enter the first material rack 2.

[0031] Furthermore, the surface of the cam 7 is provided with friction texture 17, which can increase frictional resistance and improve the limiting of the cam 7 on the round tube.

[0032] Specifically, the lifting device includes a lifting cylinder 8 located on the frame 1. A lifting plate 9 is mounted on the piston rod of the lifting cylinder 8, and several guide rods 10 are mounted on the bottom of the lifting plate 9, sliding relative to the frame 1. When the round tube is output from the first material rack 2, it first falls onto the lifting plate 9. Then, the lifting cylinder 8 is activated, extending its piston rod and driving the lifting rod upwards until the round tube flows into the ejection device. During this process, because the round tube is relatively long, and the size of the lifting plate 9 matches the tube, the guide rods 10, through their sliding connection with the frame 1, balance the movement of the lifting plate 9, allowing the piston rod of the lifting cylinder 8 to smoothly move the lifting plate 9.

[0033] It should be noted that the lifting plate 9 has an "L"-shaped cross-section, and the lifting plate 9 also has a slope, which facilitates the output of the round tube from the lifting plate 9 to the ejection device. During this process, when the piston rod of the lifting cylinder 8 is not extended, the lifting plate 9 and the frame 1 form a "U"-shaped groove. When the round tube falls into the lifting plate 9, the frame 1 provides a limiting mechanism, preventing the round tube from flowing out of the lifting plate 9 during this stage. When the piston rod of the lifting cylinder 8 extends, it drives the lifting plate 9 upward, releasing the limiting mechanism of the frame 1 on the round tube, allowing the round tube to be output from the lifting plate 9 to the ejection device. This achieves the connection and lifting of the round tube by the lifting device.

[0034] Specifically, the ejection device includes an ejection trough 11 located on the frame 1. The ejection trough 11 contains several support shafts 12, each with rollers 13. An ejection cylinder 14 is positioned above the ejection trough 11, and an ejection plate 15 is mounted on the sliding block of the ejection cylinder 14. When the round tube flows from the lifting plate 9 into the ejection device, it first falls into the ejection trough 11, where it is supported by the rollers 13. Then, the ejection cylinder 14 is activated, driving the ejection plate 15 to push the round tube out of the ejection trough 11 under the action of the rollers 13, into the adhesive coating production line. This achieves the output of the round tube from this equipment to the adhesive coating production line.

[0035] It should be noted that the ejector cylinder 14 is a magnetically coupled rodless cylinder, preferably the SMC CY1L series. The magnetically coupled rodless cylinder can provide good thrust and driving stability, and can meet the requirements of the solid wood material commonly used in round tubes in this equipment.

[0036] Specifically, the outflow groove 11 is provided with several mounting grooves, and the support shaft 12 is engaged with the mounting grooves. A nut 16 is provided on the support shaft 12, and the nut 16 is threadedly connected to the support shaft 12. The engagement of the support shaft 12 with the mounting grooves allows the height of the roller 13 to be adjusted. After adjustment, the support shaft 12 is locked and fixed in the outflow groove 11 by the nut 16, ensuring that the height of the outflowing round tube matches the height of the adhesive coating production line. This provides high adaptability, enabling the equipment to be easily adjusted for production lines and adapted to different production line needs.

[0037] Specifically, both the lifting cylinder 8 and the ejection cylinder 14 are connected to an external high-pressure air source, and the lifting cylinder 8, the ejection cylinder 14, and the motor 5 are all electrically connected to an external control signal. The lifting cylinder 8 and the ejection cylinder 14 are driven by an external high-pressure air source, while the starting of the lifting cylinder 8, the ejection cylinder 14, and the motor 5 is controlled by an external control signal, achieving fully automated production on the production line. When a missing round tube is detected on the adhesive coating line, the corresponding sensor sends a signal to the signal processing unit, which then sends a control signal to the lifting cylinder 8, the ejection cylinder 14, or the motor 5, collectively outputting the round tube. The working principles of the sensors, signal processing units, and other related circuit control are common techniques used by those skilled in the art and will not be described further; the working principles of the lifting cylinder 8, the ejection cylinder 14, and the motor 5 have been explained previously and will not be repeated here.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
