Description

Technical Field

[0001] This invention relates to the field of foamed silicone rubber strip production technology, specifically to a foamed silicone rubber strip production transfer vehicle. Background Technology

[0002] Foamed silicone rubber strips use silicone rubber (mainly composed of silicon dioxide) as the base material. A foaming agent is added to the rubber compound, and the mixture is heated and vulcanized under pressure to cause the silicone rubber to foam. The expansion of the rubber compound forms a sponge-like cell structure. The amount of gas generated by the foaming agent, the viscosity of the rubber compound, and the vulcanization speed directly affect the final cell quality. Before curing, foamed silicone rubber strips (especially room temperature vulcanization condensation type) should avoid prolonged or excessive air contact, primarily to prevent moisture absorption that could lead to surface skinning, abnormal bubbles, or hindered curing.

[0003] Chinese patent CN202610136194.0 discloses a high-elasticity, anti-aging foamed silicone sealant, belonging to the field of sealing material technology. It is prepared from raw materials such as methyl vinyl silicone rubber, fumed silica, and hydroxyl-terminated polydimethylsiloxane in specific weight proportions, and obtained through processes such as mixing, foaming, and vulcanization. This sealant has an apparent density of 0.3-0.6 g / cm³, a Shore A hardness of 25-45, a tensile strength ≥2.5 MPa, an elongation at break ≥350%, and high performance retention after aging at 150℃ for 1000 hours, exhibiting both excellent elasticity and anti-aging properties.

[0004] The high-elasticity, anti-aging foamed silicone seal disclosed in this patent often encounters problems such as skin formation and abnormal bubbles on the seal surface when the product is transported after molding due to contact with air and moisture, resulting in a large amount of manual handling and fingerprint contact affecting product quality. Summary of the Invention

[0005] To address the above problems, this invention provides a production transfer vehicle for foamed silicone rubber strips. By setting the door assembly and pallet assembly in linkage, the door can be opened and closed quickly when the rubber strip enters and exits the outer frame of the storage compartment. Furthermore, through the engagement and pushing parts of the retrieval mechanism, the rubber strip is automatically transferred from the storage compartment to the rack. This solves the technical problems of convenient storage and retrieval, reduced air contact, and labor saving during the transfer of foamed silicone rubber strips.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A transfer vehicle for producing foamed silicone rubber strips includes a mobile chassis with a storage compartment. The storage compartment includes an outer frame, a door assembly, and a tray assembly. The tray assembly drives the door assembly to open and extends out of the outer frame for storing or retrieving rubber strips.

[0007] As an improvement, the door assembly includes a door and a drive chain, the drive chain includes a pushing part and a pulling part, and the door is provided with a pull rod body, the pull rod body being connected to the pulling part; The pallet assembly includes a pusher that contacts the pusher portion to drive the drive chain, and the compartment door is pulled open by the pull portion.

[0008] As an improvement, the door assembly includes a cover plate hinged to the outer frame of the storage compartment. After the pallet assembly enters the outer frame of the storage compartment, it abuts against the cover plate, causing the cover plate to cover the pallet assembly. When the pallet assembly extends out of the outer frame of the storage compartment, the cover plate flips up and connects with the end of the door.

[0009] As an improvement, the door assembly further includes a sliding groove, on which a pin is provided to cooperate with the sliding groove, and the door is guided to slide by the sliding groove.

[0010] As an improvement, the pallet assembly includes a carrying tray, a connecting rod, and a drive wheel. The carrying tray is connected to the outer frame of the storage compartment via the connecting rod, and the drive wheel transmits power to the connecting rod to move the carrying tray in and out of the outer frame of the storage compartment.

[0011] As an improvement, the tray assembly also includes a flap that is disposed on the tray and can be flipped relative to the tray.

[0012] As an improvement, a picking mechanism is also included, which includes a meshing member and a pushing member configured as a gear. The pushing member is rigidly connected to the flip plate. After the pushing member contacts the meshing member, the pushing member rotates, driving the flip plate to perform a flipping motion.

[0013] As an improvement, the retrieval mechanism also includes a hanging bracket, which receives the rubber strip delivered by the flip plate when the flip plate is flipped into place.

[0014] As an improvement, the bracket is cantilevered, and the cantilevered end of the bracket is provided with a stop hook to prevent the rubber strip from slipping off.

[0015] As an improvement, the hanger is configured with spaced teeth, and the flip plate is provided with support strips that are spaced apart from the hanger. The support strips can transfer the rubber strips to the hanger.

[0016] The beneficial effects of this invention are as follows: (1) By setting the door assembly to be driven by the pallet assembly, the opening and closing of the door is reliable and convenient, and the rubber strip is sealed inside the outer frame of the door in time, reducing the time of contact with the outside air; (2) The present invention provides a tray assembly that extends out of the outer frame of the storage compartment for storing or retrieving rubber strips, which is convenient to operate, saves placement time and reduces the workload of handling. (3) The present invention enables the flip plate to flip by setting the top moving part and the meshing part to mesh and drive, so that the rubber strip on the flip plate can be quickly taken out without manual intervention, and the structure is practical. (4) By setting up a hanging rack to receive the rubber strips delivered by the pallet assembly, the present invention saves manpower for handling, reduces the time for manual touching of the rubber strips, and effectively reduces the probability of dirt appearing on the surface of the rubber strips.

[0017] In summary, this invention has the advantages of convenient operation, prevention of dirt, practicality and reliability, and is especially suitable for the field of foamed silicone rubber strip production technology. Attached Figure Description

Detailed Implementation

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

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1: like Figures 1 to 4 As shown, a foamed silicone rubber strip production transfer vehicle includes a mobile chassis 1, on which a storage compartment 2 is carried. The storage compartment 2 includes an outer frame 21, a door assembly 22, and a tray assembly 23. The tray assembly 23 drives the door assembly 22 to open and extend out of the outer frame 21 for storing or retrieving rubber strips.

[0023] It should be noted that the mobile chassis 1 can be a self-moving body containing a wheel system or a body propelled by external force; the way the pallet assembly 23 enters and exits relative to the outer frame 21 of the compartment is not limited to pulling and translating or swinging along an arc.

[0024] In a preferred embodiment, the door assembly 22 includes a door 221 and a drive chain 222. The drive chain 222 includes a pushing part 2221 and a pulling part 2223. The door 221 is provided with a pull rod body 2211, which is connected to the pulling part 2223. The pallet assembly 23 includes a top actuator 231, which contacts the top actuator 2221 to drive the drive chain 222 to rotate, and the door 221 is pulled open by the pull part 2223.

[0025] It should be noted that the top moving part 2221 may be provided with a buckle-shaped protrusion 2222. When the pallet assembly 23 is pulled outward from the outer frame 21 of the bin, the top moving part 231 contacts the top moving part 2221 to make the drive chain 222 run until the top moving part 231 reaches the outside of the outer frame 21 of the bin. Then, the top moving part 231 disengages from the top moving part 2221 of the drive chain 222, and the drive chain 222 completes the opening of the bin door 221 and stops at this position.

[0026] In a preferred embodiment, the door assembly 22 includes a cover plate 223, which is hinged to the outer frame 21 of the storage compartment. After the pallet assembly 23 enters the outer frame 21 of the storage compartment, it abuts against the cover plate 223, causing the cover plate 223 to cover the pallet assembly 23. When the pallet assembly 23 extends out of the outer frame 21 of the storage compartment, the cover plate 223 flips up and connects with the end of the door 221.

[0027] It should be noted that hooking holes can be provided on the cover plate 223, and hook-shaped areas can be provided at the mating point between the door 221 and the cover plate 223 to ensure that the door 221 and the cover plate 223 are firmly hooked together.

[0028] It should also be noted that the cover plate 223 is designed in an L-shape, and its center of gravity is set at the short side 2231 of the L-shape through counterweight calculation. In its natural state, due to the position setting of the center of gravity and the center of rotation, the long side 2232 of the L-shape of the cover plate 223 is raised. After the pallet assembly 23 enters the outer frame 21 of the warehouse, it abuts against the short side 2231 of the cover plate 223, causing the long side 2232 of the cover plate 223 to separate from the warehouse door 221, and the long side 2232 covers the pallet assembly 23, thereby covering the rubber strip for further protection.

[0029] In a preferred embodiment, the door assembly 22 further includes a sliding groove 224, on which a pin 2212 is provided to cooperate with the sliding groove 224, and the door 221 is guided to slide by the sliding groove 224.

[0030] It should be noted that the slide 224 is set as an upward curved trajectory, which allows the door 221 to move smoothly along the slide 224 when it is opened. More importantly, after the door 221 is separated from the cover plate 223, it can swing down by its own weight until the door 221 is closed.

[0031] In a preferred embodiment, the pallet assembly 23 includes a carrying tray 232, a connecting rod 233, and a drive wheel 234. The carrying tray 232 is connected to the outer frame 21 of the storage compartment via the connecting rod 233. The drive wheel 234 transmits power to the connecting rod 233, causing the carrying tray 232 to move in and out of the outer frame 21 of the storage compartment.

[0032] It should be noted that the drive wheel 234 can be rotated manually or automatically by electric control, and the number of connecting rods 233 on one side can be set to two or more to ensure that the cargo tray 232 enters and exits the outer frame 21 of the compartment in a parallel state relative to the ground.

[0033] Example 2: like Figures 5-8 As shown, in this embodiment, the tray assembly 23 further includes a flip plate 235, which is disposed on the loading tray 232 and can be flipped relative to the loading tray 232.

[0034] In a preferred embodiment, the device further includes a taking mechanism 3, which includes a meshing member 31. The actuating member 231 is configured as a gear. The actuating member 231 is rigidly connected to the flip plate 235. After the actuating member 231 contacts the meshing member 31, the actuating member 231 rotates, driving the flip plate 235 to perform a flipping motion.

[0035] It should be noted that the picking mechanism 3 can be set at the station where the rubber strip is used. The engaging member 31 is located on the movement trajectory of the tray assembly 23. After engaging with the top member 231, the engaging member 31 drives the top member 231 to rotate. It is configured to allow the top member 231 to rotate more than 90°, so that the flip plate 235 can tilt the rubber strip, which is conducive to the rubber strip entering the picking mechanism 3.

[0036] In a preferred embodiment, the taking mechanism 3 further includes a hanging bracket 32, which receives the rubber strip delivered by the flip plate 235 when the flip plate 235 is flipped into place.

[0037] In a preferred embodiment, the bracket 32 ​​is cantilevered, and the cantilevered end of the bracket 32 ​​is provided with a stop hook 321 to prevent the rubber strip from slipping off.

[0038] It should be noted that the bracket 32 ​​can be configured to have an upward tilt relative to the horizontal plane, which facilitates receiving the rubber strip delivered by the flip plate 235, while the stop hook 321 prevents the rubber strip from slipping off the bracket 32.

[0039] In a preferred embodiment, the hanger 32 is configured with spaced teeth, and the flip plate 235 is provided with a support strip 2351 that is spaced apart from the hanger 32. The support strip 2351 can transfer the rubber strip to the hanger 32.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
