Description
Technical Field
[0001] This utility model relates to the field of auxiliary transportation technology, and in particular to an auxiliary transportation device for dye production. Background Technology
[0002] Auxiliary transport devices for dye production are specialized equipment used in chemical workshops to transfer bagged dye powders. They primarily address the short-distance handling of bagged dyes between production lines, storage areas, and packaging lines. In dye production workshops, powdered or granular dyes are typically packaged in woven bags weighing 25-50 kg / bag and transferred between production lines, storage areas, and packaging lines using manual forklifts or flatbed trolleys. Existing transport methods suffer from two major structural defects.
[0003] In the dye production process, powdered or granular dyes are typically packaged in woven bags for transport within the workshop. Existing transportation equipment faces a dual dilemma: First, during handling, the continuous bumping and squeezing of the bagged dye creates major dust leakage channels at the bag openings and side seams. Leaked dye not only contaminates workshop floors and equipment but also significantly increases cleaning difficulty. Second, while fixed barriers installed to curb leakage reduce the risk of tipping, their enclosed structure forces workers to laboriously lift heavy bags significantly above the barriers to load them, drastically reducing transport efficiency. More importantly, an inherent gap remains between the fixed barriers and the bags, meaning the dust leakage problem at the seams remains fundamentally unresolved, creating a fundamental contradiction between leakage prevention requirements and operational convenience.
[0004] Therefore, this application provides an auxiliary transport device for dye production to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide an auxiliary transportation device for dye production, which solves the problems of serious dust leakage at the seams of dye bags and low loading and unloading efficiency of fixed enclosures during transportation in existing transportation devices.
[0006] To solve the above-mentioned technical problems, this utility model provides an auxiliary transportation device for dye production, including a transportation vehicle assembly and a leak-proof assembly installed on the transportation vehicle assembly;
[0007] The transport vehicle component includes a carrying platform, with wheels installed at the four corners of the bottom of the carrying platform, and a vertical push handle installed at the rear end of the carrying platform;
[0008] The leak prevention component includes a first vertical baffle, which is fixedly installed on the rear edge of the support platform. A second vertical baffle is fixedly installed on the front edge of the support platform. The top of the second vertical baffle is hinged to a first flip baffle, and the first flip baffle can be flipped and unfolded around the hinge axis in the forward direction.
[0009] The top of the first vertical baffle is hinged to the second flip baffle, and the second flip baffle can be flipped and unfolded in the backward direction around the hinge axis. A locking component is provided on the front edge of the second flip baffle for connecting with the upper edge of the first flip baffle.
[0010] The inner walls of the first vertical baffle, the second vertical baffle, the first flip baffle, and the second flip baffle are all provided with elastic compensation layers; wherein, when the first flip baffle is rotated to the vertical state, it and the second vertical baffle together form a continuous vertical barrier, at which time the upper edge of the first flip baffle and the front edge of the second flip baffle are in a lockable position.
[0011] The further improvement of this utility model is that: the height of the second vertical baffle H2 is equal to the vertical height H0 of a single-layer standard dye bag; the height of the first flip baffle H3 is equal to (n-1)×H0, where n is the number of stacked layers; and the height of the first vertical baffle H1 is equal to H2+H3=n×H0.
[0012] A further improvement of the present invention is that the locking assembly includes a first locking piece fixed to the front edge of the second flip baffle and a second locking piece fixed to the upper edge of the first flip baffle. The first locking piece and the second locking piece have threaded holes respectively. A screw is screwed into the threaded hole, and a rotating handle is provided at the end of the screw. The screw achieves vertical locking of the first flip baffle and the second flip baffle.
[0013] A further improvement of this utility model is that the first vertical baffle and the second vertical baffle are parallel to each other and both are perpendicular to the upper surface of the bearing platform.
[0014] A further improvement of this utility model is that: vertically extending positioning baffles are respectively provided on both sides of the first vertical baffle, the positioning baffles are parallel to the forward direction and the height is the same as the height of the first vertical baffle; the positioning baffles are used to constrain the lateral offset of adjacent dye bags.
[0015] A further improvement of this utility model is that the bottom of the first vertical baffle and the second vertical baffle are fixed to the bearing platform by countersunk rivets.
[0016] A further improvement of this utility model is that the elastic compensation layer is a closed-cell silicone rubber sponge layer with a thickness of 30-50mm and a compression resilience of ≥90%.
[0017] A further improvement of this utility model is that: the upper surface of the bearing platform is provided with transverse anti-slip ridges, the height of which is 3-5mm and the spacing is 50-80mm.
[0018] By adopting the above technical solution, this utility model has the following beneficial effects:
[0019] 1. The auxiliary transportation device for dye production provided by this utility model, through the combination of a flip-up baffle and an elastic compensation layer, can fully unfold the baffle to release the operating space during loading and unloading operations. Workers can directly push the dye bags into the carrying platform without having to lift the heavy bags, which significantly reduces labor intensity. When the transportation is closed, the elastic compensation layer fits tightly against the seam area of the bag body, forming a directional physical seal, especially for the bag opening seam with the highest risk of leakage, blocking the dust escape channel from the source.
[0020] 2. This utility model provides an auxiliary transport device for dye production, which presets baffle heights for transporting multiple layers of dyes to achieve precise protection. Specifically, the height of the second vertical baffle is fixed at the height of a single bag, H2=H0, ensuring that the top seam of the bottom bag is always precisely aligned with the sealing area in the middle of the baffle; simultaneously, the height of the first flip baffle is preset according to the target number of stacked layers, H3=(n-1)×H0, completely covering the side seams of multiple bags in the upper layer. This preset height combination ensures that during daily operation, workers only need to stack the bags according to the fixed number of layers, without any height adjustment, to simultaneously achieve tight protection between the top seam of the bottom bag and the side seam of the upper bag, eliminating both leakage blind spots and the tedious operation of repeated adjustments.
[0021] 3. This utility model provides an auxiliary transport device for dye production, wherein the lateral positioning guard and the transverse anti-slip protrusions of the carrying platform work together. The positioning guard is set perpendicular to the direction of travel, effectively restraining the lateral displacement of the bag; the anti-slip protrusions on the surface of the carrying platform are arranged at specific intervals, greatly enhancing the friction of the bag bottom. The three-dimensional stabilization system constructed by the two ensures zero displacement of the bag when turning or bumping during transport, so that the sealing performance of the elastic compensation layer reaches the optimal state.
[0022] 4. The auxiliary transport device for dye production provided by this utility model, wherein the countersunk rivet fixing method eliminates the risk of scratching the woven bag; the screw locking mechanism driven by the rotating handle generates a vertical locking force through the thread engagement, and the first flip baffle and the second flip baffle can be pressed together in a few seconds with just one hand rotation, which avoids the complicated operation of traditional bolts and eliminates rigid compression damage to the bag.
[0023] 5. The auxiliary transportation device for dye production provided by this utility model fundamentally resolves the long-standing contradiction in the industry. While ensuring the dust sealing performance at the joints, it greatly improves the convenience of loading and unloading operations. It is especially suitable for high-frequency short-distance transfer scenarios, providing dual protection for the cleanliness of the dye production environment and the occupational health of workers.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0037] The present invention will be further explained below with reference to specific embodiments.
[0038] like Figures 1-8 As shown, this embodiment provides an auxiliary transportation device for dye production, including a transport vehicle assembly 1 and a leak-proof assembly 2 installed on the transport vehicle assembly 1. The transport vehicle assembly 1 includes a high-strength load-bearing platform 11, which is made of corrosion-resistant steel plate, and has four corner-mounted universal wheels 12 with brakes to ensure flexible steering and stable parking. The rear end of the load-bearing platform 11 is welded with an ergonomic vertical push handle 13, the surface of which is provided with anti-slip texture for comfortable force application by the operator.
[0039] like Figures 1-6 As shown, in this embodiment, the leak-proof component 2 includes a first vertical baffle 21 and a second vertical baffle 22, which are vertically fixed to the rear and front edges of the support platform 11 respectively by countersunk rivets 27. The top of the second vertical baffle 22 is hinged to the first flip baffle 23 via a heavy-duty hinge, allowing the first flip baffle 23 to flip forward at a large angle, completely releasing the loading and unloading space. The top of the first vertical baffle 21 is also hinged to the second flip baffle 24, allowing it to flip backward. The two vertical baffles remain strictly parallel and perpendicular to the support plane, ensuring structural stability. This allows for flexible switching between a fully open operating space during loading and unloading and a sealed state during transportation.
[0040] like Figure 2 , Figure 3As shown, in this embodiment, the locking assembly 3 includes a precisely aligned first locking piece 31 and a second locking piece 32, which are respectively fixed to the front edge of the second flip baffle 24 and the upper edge of the first flip baffle 23. The two locking pieces have coaxial threaded holes 33, which, in conjunction with the screw 34, achieve mechanical locking. Rotating the handle 35 to drive the screw 34 in generates a strong downward vertical pressure, ensuring the baffle system is tightly closed.
[0041] like Figure 1 As shown, in this embodiment, when the first flip baffle 23 rotates to a vertical position, it and the second vertical baffle 22 together form a continuous vertical barrier. At this time, the upper edge of the first flip baffle 23 and the front edge of the second flip baffle 24 are in a lockable position. The height H2 of the second vertical baffle 22 is equal to the vertical height H0 of a single-layer standard dye bag; the height H3 of the first flip baffle 23 is equal to (n-1)×H0, where n is the number of stacked layers; the height H1 of the first vertical baffle 21 is equal to H2+H3=n×H0.
[0042] like Figure 1 As shown, in this embodiment, the inner walls of the first vertical baffle 21, the second vertical baffle 22, the first flip baffle 23, and the second flip baffle 24 are all provided with an elastic compensation layer 25; the elastic compensation layer 25 is a closed-cell silicone rubber sponge layer with a thickness of 30-50mm and a compression rebound rate of ≥90%. When the baffle is closed, the elastic compensation layer 25 is squeezed and adaptively fills the gap, forming a directional sealing pressure in the seam area.
[0043] like Figures 1-6 As shown, in this embodiment, vertically extending positioning edges 26 are respectively provided on both sides of the first vertical baffle 21. The positioning edges 26 are parallel to the forward direction and have the same height as the first vertical baffle 21. The positioning edges 26 are used to constrain the lateral offset of adjacent dye bags. The bottoms of the first vertical baffle 21 and the second vertical baffle 22 are fixed to the carrying platform 11 by countersunk rivets 27. The upper surface of the carrying platform 11 is provided with transverse anti-slip ridges 28, the height of which is 3-5mm and the spacing is 50-80mm. The positioning edges 26 and the transverse anti-slip ridges 28 of the carrying platform 11 work together. The positioning edges 26 are set vertically parallel to the forward direction, effectively constraining the lateral offset of the bag. The anti-slip ridges 28 on the surface of the carrying platform 11 are arranged at specific intervals, greatly enhancing the friction of the bag bottom. The three-dimensional stabilization system constructed by the two ensures zero displacement of the bag when turning or bumping during transportation, so that the sealing performance of the elastic compensation layer 25 reaches the optimal state.
[0044] This utility model also provides the operating principle of an auxiliary transportation device for dye production:
[0045] The operator first unlocks the rotary handle 35, loosens the screw 34 to release the locking component 3, and then flips the first flip baffle 23 forward and the second flip baffle 24 backward to fully open the leak-proof component 2. Next, the dye bag is pushed horizontally into the carrying platform 11, and the bag position is calibrated using the positioning guards 26 on both sides. When stacking multiple layers, ensure that the top of the bottom bag is flush with the second vertical baffle 22. After loading, the first flip baffle 23 is flipped to a vertical position to form a continuous barrier with the second vertical baffle 22, and the second flip baffle 24 is flipped simultaneously. The first locking piece 31 and the second locking piece 32 of the locking assembly 3 are precisely aligned when the horizontal position is reached. Finally, the rotating handle 35 is tightened to drive the screw 34 into the threaded hole 33, generating a vertical locking force to press the baffle system. At this time, the elastic compensation layer 25 is deformed by compression, automatically filling the gap between the baffle and the bag body and forming a directional seal in the seam area. When the operator holds the push handle 13 to transport the bag, the anti-slip ridges 28 of the carrying platform 11 and the wheels 12 work together to ensure stable transportation. The countersunk rivets 27 fix the structure to avoid the risk of scraping the bag throughout the process. After arriving at the destination, the reverse operation is used to unlock and unload the bag.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
