Description

Technical Field

[0001] This invention relates to the field of smoked sheet adhesive preparation technology, and more specifically to a smoked sheet adhesive preparation system. Background Technology

[0002] Smoked sheet rubber is a raw rubber sheet made from natural rubber latex through coagulation, pressing, and drying with tree smoke. It is the most important commercial form of natural rubber.

[0003] Currently, smoked sheet adhesive is mainly produced through the following processes:

[0004] Rubber trees are tapped to collect fresh, milky-white latex. This latex is then diluted with water and filtered to remove bark, sand, and other impurities. Next, a weak acid (usually formic acid or acetic acid) is added, causing the rubber particles in the latex to coagulate into solid clumps. These clumps are then pressed into thin sheets with a diamond-shaped pattern on the surface using a roller calender. The pattern increases the surface area, facilitating subsequent drying. Smoke drying: This is the most crucial step. The pressed sheets are hung in a fumigation chamber and smoked with the smoke produced by burning wood (usually resin-free hardwood). This process typically lasts several days.

[0005] There are two main types of equipment for producing smoked sheet rubber: one involves coagulating the rubber, cutting it into small sheets, and then pressing it; the other involves solidifying it into a cylindrical shape, then cutting it into continuous sheets using a rotary cutter, pressing it, and then slitting it into smaller sheets. Both types of equipment require a pressing process, involve a significant amount of manual labor during production, and result in some variation between sheets, leading to poor product consistency. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a smoked sheet adhesive sheeting system that employs a one-step molding method, eliminating the need for additional slicing operations and enabling automated production of smoked sheet adhesive sheets, thereby effectively improving work efficiency and product consistency.

[0008] A smoked sheet film forming system, comprising:

[0009] The tray feeding line is a mold used to transport empty trays;

[0010] The dispensing line is used to mix adhesive and acid, and then deliver the mixture into an empty mold.

[0011] A transfer line, located downstream of the injection line, is used to send the mold after injection into the coagulation zone, where the mixed solution solidifies into a gel sheet.

[0012] Furthermore, the dispensing line includes:

[0013] Collection tank, used to store adhesive liquid;

[0014] Acid storage tanks are used to store acids;

[0015] The adhesive-acid mixing tank, connected to the collection tank and acid storage tank, is used for mixing adhesive and acid;

[0017] Furthermore, a skimming mechanism is provided on the transfer line. The skimming mechanism is located downstream of the glue injection line and is used to skim off the foam inside the mold after glue injection.

[0018] Furthermore, the descaling mechanism includes:

[0022] Furthermore, a capping mechanism is arranged downstream of the shaving mechanism for capping the mold after glue injection.

[0023] Furthermore, the smoked sheet film forming system also includes:

[0024] The discharge line, located downstream of the solidification area, is used to discharge the solidified gel.

[0025] The outgoing line is equipped with a flipping mechanism and a mold-removing mechanism. The flipping mechanism is used to vertically flip the mold and solidified sheet sent out from the storage area so that the cover is located at the bottom.

[0026] The mold removal mechanism is used to remove the mold and the cover.

[0027] Furthermore, the flipping mechanism includes:

[0028] Clamping roller assembly for gripping molds and covers;

[0029] A flipping unit, connected to the clamping roller assembly, is used to flip the clamping roller assembly.

[0030] Furthermore, the mold-taking mechanism includes:

[0031] The mold-removing unit, located downstream of the flipping mechanism, is used to remove the mold. After the mold is removed, the gel sheet is placed on the cover.

[0032] The cap removal unit, located downstream of the mold removal unit, is used to remove the cap.

[0033] Furthermore, the cap-removing unit includes:

[0034] A separating spatula, configured with an adjustable angle, has its bottom positioned in front of the gel sheet and the cap, for separating the gel sheet from the cap;

[0035] The conveying unit, located downstream of the separating shovel, is used to convey the gel sheets separated by the separating shovel, and the lower cover is sent out along the outgoing line.

[0036] Furthermore, the mold has a first inclined portion on its inner side, the first inclined portion is located in the conveying direction, and the injection height of the injection head is lower than the lowest point of the first inclined portion;

[0037] The cover is larger than the mold and has a second inclined portion thereon, which corresponds to the first inclined portion.

Detailed Implementation

[0061] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0062] Example 1

[0063] like Figure 1As shown, the present invention provides a tobacco sheet adhesive forming system, including: a tray feeding line 1, an adhesive injection line 2, a transfer line 3, a coagulation zone 4, and an outgoing line 5. The tray feeding line 1 is a conventional conveyor used to transport empty tray molds 6. The adhesive injection line 2 is used to mix fresh latex and acid and inject it into the empty tray mold 6. The transfer line 3 covers the mold 6 after adhesive injection, removes the foam, and sends it to the coagulation zone 4. The mixture of latex and acid is allowed to stand and solidify, forming a gel sheet 7 in the mold 6, which is then outgoing. After removing the mold 6 and the cover 62 at the outgoing line 5, the gel sheet 7 is transported to downstream equipment.

[0064] like Figure 15 As shown, mold 6 adopts a disc-type structure. Both ends of mold 6 are first inclined portions 61. The injection height is lower than the lowest point of the first inclined portion 61, forming a square liquid-filling area in mold 6. The first inclined portion 61 mainly facilitates the skimming operation. Figure 16 As shown, the cap 62 corresponds to the mold 6 and is provided with a corresponding second inclined portion 63, which corresponds to the first inclined portion 61. On one hand, this aligns with the first inclined portion 61, facilitating alignment with the liquid-filling area of ​​the mold 6. A gap is maintained between the cap 62 and the liquid surface of the mold 6, such that the gel sheet 7 can fall onto the cap 62 after being flipped. On the other hand, the second inclined portion 63 also facilitates the subsequent separation of the gel sheet 7 from the cap 62. The size of the cap 62 is larger than the size of the mold 6 to facilitate subsequent capping and the flipping of the gel sheet 7 onto the cap 62.

[0065] like Figure 2-3 As shown, the latex injection line 2 includes: a collection tank 21, a latex mixing tank 22, an acid storage tank 23, a latex-acid mixing chamber 24, and an injection head 25. The collection tank 21 is used to store fresh latex and has a built-in sedimentation tank 211 for settling some impurities. The collection tank 21 is connected to the latex mixing tank 22 via a feeder. The latex mixing tank 22 is used to stir the latex to make it more uniform. The latex mixing tank 22 and the acid storage tank 23 are connected to the latex-acid mixing chamber 24 via a pump pipeline. The latex-acid mixing chamber 24 is equipped with a level sensor to detect the liquid level in the latex-acid mixing chamber 24. A corresponding flow valve is installed on the pump pipeline, and the flow valve is controlled by a PLC to control the corresponding flow rate to control the mixing ratio of the two. The outlet end of the latex-acid mixing chamber 24 is the injection head 25. The injection head 25 is controlled by a solenoid valve. After the latex and acid are mixed, they are quantitatively injected into the empty mold 6 (without a cap 62) delivered by the injection head 25, forming a mixed liquid layer with a height of 3-5mm in the mold 6, and then entering the transfer line 3 through the conveyor.

[0066] Transfer line 3 is a conveyor used to transport mold 6 containing the mixture. A skimming mechanism 31 and a capping mechanism 32 are installed on the conveyor line. The skimming mechanism 31, mounted on transfer line 3, replaces manual labor in removing foam from the gel-acid mixture, ensuring the gel's molding effect. The capping mechanism 32 is used to cap the mold 6, facilitating subsequent demolding of the gel 7.

[0067] like Figure 4-6 As shown, the skimming mechanism 31 includes: a support 311, a skimming motor 312, and a skimming plate 313. The support 311 serves as the main weighing component, mounted on the transfer line 3 and located downstream of the colloid-acid mixing chamber 24. The skimming motor 312 is connected to the chain mechanism for transmission. The skimming plate 313 is a single piece, mounted on the chain mechanism, and moves with the chain mechanism. When the skimming motor 312 drives the chain mechanism to rotate, it drives the skimming plate 313 to skim the colloid. The skimming plate 313 contacts the surface of the colloid-acid mixture in the mold 6 and is opposite to the conveying direction of the mold 6. The skimming plate 313 lightly scrapes the surface of the colloid-acid mixture. At the same time, the mold 6 containing the mixture is also conveyed forward. The skimming plate 313 scrapes the surface foam from the first inclined part 61 at the rear end of the mold 6. The skimmer plate 313 can be made of a rigid plate, with the rear end of the skimmer plate 313 folded back to ensure that the foam is skimmed off. Alternatively, it can be made of a flexible material, such as a silicone plate, which is used to ensure that the foam is skimmed off by fitting its flexibility into the first inclined portion 61. In this embodiment, the upper part of the skimmer plate 313 is a rigid fixed plate for easy assembly, and the lower part is a flexible silicone plate, which is fixedly connected to the upper fixed plate. The flexibility of the silicone plate ensures that the foam is skimmed off.

[0068] Downstream of the skimming mechanism 31, a covering mechanism 32 is arranged, such as... Figure 7 As shown, the capping mechanism 32 is a robotic arm that caps the mold 6 after skimming by gripping the cap 62 or by suctioning the cap 62 with negative pressure, thus forming a relatively complete box structure. After capping, the mold 6 can be sent to the coagulation area 4 for static solidification via a shuttle or other equipment, thereby solidifying the mixture into a gel sheet 7. The mold 6 can also be sent out of the warehouse via a shuttle, with the mold 6 containing the gel sheet 7 being sent to the outbound line 5.

[0069] The outbound line is equipped with a flipping mechanism 51 and a mold removal mechanism 52. The mold removal mechanism 52 is located downstream of the flipping mechanism 51. The line flips the mold 6 180° around the horizontal axis through the flipping mechanism 51, so that the gel sheet 7 falls onto the cover 62. Then, the mold removal mechanism 52 removes the mold 6 and the cover 62, thereby realizing the demolding operation of the gel sheet 7.

[0070] Specifically, such as Figure 8-9As shown, the flipping mechanism 51 includes a clamping roller assembly 511 and a flipping unit. The clamping roller assembly 511 consists of two layers of rollers, the height of which is approximately the same as the thickness of the mold 6 with the cover 62. The bottom roller is level with the conveyor rollers to allow the mold 6 to enter the clamping roller assembly 511 normally. The clamping roller assembly 511 can also be height-adjustable, with the upper roller having a liftable structure. This structure is achieved by a cylinder lifting method, which will not be described in detail here. After the mold 6 is fully inside the clamping roller assembly 511, it is flipped by the flipping unit. This unit is integrally connected to the clamping roller assembly 511. The flipping motor of the flipping unit is connected to a fixed wheel outside the clamping roller assembly 511. As the flipping motor rotates, it drives the fixed wheel to rotate, which in turn drives the clamping roller assembly 511 to rotate, thus flipping the mold 6.

[0071] like Figure 10-14 As shown, the mold-removing mechanism 52 includes a mold-removing unit and a cover-removing unit. The mold-removing unit is located downstream of the flipping mechanism 52. In this embodiment, it is a robotic arm used to pick up the mold 6. The robotic arm adopts a shaking control method. After picking up the mold 6, it ensures that the gel sheet 7 can fall onto the cover 62 by shaking it slightly. After the shaking is finished, the mold 6 is removed.

[0072] The cap removal unit is located downstream of the mold removal unit. It includes a separating shovel 523 and a conveying unit 524. The bottom of the separating shovel 523 is equipped with a spring 525 and a limiting structure 526. By having the end of the spring 525 hang on the limiting structure 526 at different positions, the angle of the separating shovel 523 can be adjusted. That is, the angle of the separating shovel 523 when scooping the gel sheet 7 can be adjusted to facilitate the separation of the gel sheet 7 from the cap 62. The separating shovel 523 scoops up the gel sheet 7 from the edge of the second inclined portion 63 of the cap 62, thereby allowing the gel sheet 7 to enter the conveying unit 524 and be sent away. The lower cap 62 is then conveyed away normally by the conveyor. The separation of the gel sheet 7 from the cap 62 is achieved by scooping the gel sheet.

[0073] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
