Description

Technical Field

[0001] This utility model belongs to the field of ultra-flexible fabric roll transport technology, and in particular relates to an ultra-flexible fabric roll transport trolley. Background Technology

[0002] Currently, ultra-soft fabric rolls are widely used in textiles and apparel, infant products, home decoration, and electronic device cushioning packaging due to their soft texture, delicate surface, and skin-friendly properties. In the production, processing, warehousing, and customer delivery of ultra-soft fabric rolls, transportation is a key process connecting all stages. Its transportation efficiency, fabric roll quality protection effect, and equipment compatibility directly affect the company's production rhythm and product qualification rate. Therefore, special transport trolleys have become the core auxiliary equipment in the ultra-soft fabric roll circulation process. However, the current transportation equipment for ultra-soft fabric rolls still has many technical defects and cannot meet the needs of efficient, safe, and high-quality transportation.

[0003] The specifications of ultra-soft fabric rolls need to be adjusted according to the needs of downstream customers. The diameter usually covers 50cm-150cm and the length covers 100cm-200cm. However, the load-bearing spacing (i.e. the distance between the supporting structures) of existing transport trolleys is mostly fixed. For fabric rolls with smaller diameters, the fixed spacing is too large, which can easily cause the center of gravity of the fabric roll to shift or tilt, and there is a risk of slipping during transportation. For fabric rolls with larger diameters, the fixed spacing is too small, and the fabric roll cannot be placed smoothly. It is necessary to forcibly squeeze the fabric roll or change the trolley. In order to adapt to multiple specifications of fabric rolls, some companies have to purchase multiple trolleys with different spacings, which increases the equipment purchase cost and occupies the limited workshop storage space, resulting in extremely low equipment utilization.

[0004] There is an urgent need for improvement, so we propose an ultra-soft fabric roll transport trolley. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an ultra-soft fabric roll transport trolley that allows for flexible adjustment based on the different sizes of the ultra-soft fabric rolls.

[0006] In view of this, the present invention provides an ultra-flexible fabric roll transport trolley, comprising: a base, wherein two bases are provided, each base having casters mounted on both sides of its bottom, and a support assembly mounted on the top of each base, forming a support area for supporting the ultra-flexible fabric roll between the two support assemblies; a docking cylinder is fixedly connected to the side wall of one base, and a docking post is fixedly connected to the side wall of the other base, wherein an adjustment mechanism is provided on the docking cylinder and the docking post, the adjustment mechanism being used to adjust the distance between the two bases for supporting ultra-flexible fabric rolls of different sizes; a positioning assembly, wherein the positioning assembly is disposed on the docking cylinder, the positioning assembly being used to lock the adjustment mechanism; and a reinforcement assembly, wherein the reinforcement assembly is disposed on the two bases, the reinforcement assembly being used to enhance the stability of the device.

[0007] Furthermore, the support assembly includes brackets fixedly installed on both sides of the top of the base, and a support roller is rotatably installed between the two corresponding brackets.

[0008] Furthermore, one of the brackets is threaded with a bolt, the outer end of which abuts against the outer wall of the support roller.

[0009] Furthermore, the adjustment mechanism includes a slot opened at the port of the docking cylinder, the slot being movably inserted into the docking post, a connecting cylinder being installed on one side of the top of the docking cylinder, the inner cavity of the connecting cylinder being connected to the slot, a locking post being slidably installed inside the connecting cylinder, a plurality of first teeth being fixedly installed at the bottom of the locking post, and a plurality of second teeth being fixedly installed at the top of the docking post, the second teeth corresponding to the first teeth.

[0010] Furthermore, a first spring is sleeved on the outer wall of the locking post, and the two ends of the first spring are fixedly connected to the side wall of the locking post and the corresponding side wall of the connecting cylinder, respectively.

[0011] Furthermore, symmetrical limit grooves are formed in the slot, and limit blocks are symmetrically installed on the outer wall of the docking column, with the limit blocks slidingly connected to the limit grooves.

[0012] Furthermore, the positioning component includes a mounting bracket fixedly connected to one side of the top of the docking cylinder. A stop block is movably provided through the top of the mounting bracket. A second spring is sleeved on one end of the stop block, and the two ends of the second spring are fixedly connected to the side wall of the stop block and the corresponding side wall of the mounting bracket, respectively.

[0013] Furthermore, the abutment port is provided with an inclined groove, which corresponds to one end of the top of the locking post, and the inclined surface of the inclined groove extends downward from top to bottom along the height direction of the abutment.

[0014] Furthermore, the reinforcement assembly includes a first handle rod fixedly connected to the top of one of the bases, and a second handle rod fixedly connected to the top of the other base. A limiting cylinder is fixedly connected to the lateral port at the top of the second handle rod, and the inner cavity of the limiting cylinder is slidably connected to the lateral port at the top of the first handle rod.

[0015] The beneficial effects of this utility model are: By setting two bases with casters, the trolley can be easily pushed to facilitate the convenient transportation of ultra-soft fabric rolls, reducing the intensity of manual handling. The top support component can stably support the ultra-soft fabric rolls, preventing the rolls from directly contacting the ground and causing contamination or wear. The cooperation between the docking cylinder and the docking column provides a basis for adjusting the distance between the two bases. The adjustment mechanism can flexibly adjust the distance between the two bases according to different sizes of ultra-soft fabric rolls, so that the trolley can adapt to the support needs of various specifications of fabric rolls, improving its applicability. The positioning component can lock the adjusted mechanism state to prevent the base distance from shifting due to vibration and other factors during transportation, ensuring support stability.

[0022] Reference Figures 1 to 5 A super-soft fabric roll transport trolley, comprising: The base 1 has two bases. Both bases 1 have casters 11 installed on both sides of their bottom. Each caster 11 has a locking mechanism for locking it. Support components are installed on the top of the two bases 1, and a support area for supporting the ultra-flexible fabric roll is formed between the two support components. One of the bases 1 has a docking cylinder 2 fixedly connected to its side wall, and the other base 1 has a docking column 21 fixedly connected to its side wall. The docking cylinder 2 and the docking column 21 are equipped with an adjustment mechanism, which is used to adjust the distance between the two bases 1 and to support ultra-flexible fabric rolls of different sizes. A positioning component is installed on the docking cylinder 2 and is used to lock the adjustment mechanism. The reinforcement components are mounted on two bases 1 and are used to enhance the stability of the device.

[0023] In operation, the casters 11 at the bottom of the base 1 allow the trolley to move in any direction within the plane by rolling, facilitating the transport of the ultra-flexible fabric roll. The support assembly at the top of the base 1 contacts the fabric roll, isolating it from the ground. The docking cylinder 2 of one base 1 and the docking post 21 of the other base 1 form a sliding fit structure. The adjustment mechanism adjusts the distance between the two bases 1 by changing the insertion depth of the docking post 21 in the docking cylinder 2 to accommodate fabric rolls of different sizes. When the distance is adjusted to the target position, the positioning assembly restricts the relative sliding between the docking cylinder 2 and the docking post 21, ensuring the stability of the distance between the bases 1. The reinforcement assembly reduces the deformation and swaying of the base 1, ensuring the overall structural stability.

[0024] Additional explanation is needed. Figure 2The first handle rod 15 and the limiting cylinder 17 maintain a sliding connection during use and are not completely separated. Figure 2 The diagram in the middle shows the first handle rod 15 and the limiting cylinder 17 completely separated, indicating a non-use state.

[0025] It should be noted that bolt 14 is offset from the central axis of support roller 13, and bolt 14 abuts against the side wall of support roller 13.

[0026] In the example of this application, the support assembly includes brackets 12 fixedly installed on both sides of the top of the base 1, and a support roller 13 rotatably installed between the two corresponding brackets 12. The two ends of the support roller 13 are fixedly connected to the central shaft of the corresponding bearing, and the bearing is fixedly installed on the side wall of the corresponding bracket 12.

[0027] As a preferred example of this utility model, in the support assembly, the support roller 13 is rotatably connected to the bracket 12 through a bearing or bushing, so that the support roller 13 can rotate freely around its own central axis. When the ultra-soft fabric roll is placed on two corresponding support rollers 13, the weight of the fabric roll itself makes the outer wall of the fabric roll in close contact with the outer wall of the support roller 13. When placing or taking the fabric roll, the relative motion between the fabric roll and the support roller 13 is converted into the rotational motion of the support roller 13, converting the sliding friction between the two into rolling friction and reducing the motion resistance.

[0028] In the example of this application, one of the brackets 12 is threaded with a bolt 14, and the bracket 12 has a threaded hole that is threadedly connected to the bolt 14. The outer end of the bolt 14 abuts against the outer wall of the support roller 13.

[0029] As a preferred example of this utility model, the bracket 12 has an internal threaded hole that matches the bolt 14. The bolt 14 is installed on the bracket 12 through threaded engagement, and the screw portion of the bolt 14 can move along the axis of the threaded hole. When it is necessary to fix the support roller 13, the bolt 14 is rotated clockwise, and the outer end of the screw gradually moves towards the support roller 13 until it comes into close contact with the outer wall of the support roller 13. The static friction between the screw and the support roller 13 restricts the rotation of the support roller 13. When it is necessary to restore the rotation function of the support roller 13, the bolt 14 is rotated counterclockwise, and the outer end of the screw moves away from the support roller 13. The static friction disappears, and the support roller 13 can rotate around its own axis again, realizing on-demand control of the rotation state of the support roller 13.

[0030] In the example of this application, the adjustment mechanism includes a slot 22 opened at the port of the docking cylinder 2, the slot 22 being movably inserted into the docking post 21, a connecting cylinder 24 being installed on one side of the top of the docking cylinder 2, the inner cavity of the connecting cylinder 24 being connected to the slot 22, a locking post 26 being slidably installed inside the connecting cylinder 24, a plurality of first teeth 28 being fixedly installed at the bottom of the locking post 26, and a plurality of second teeth 29 being fixedly installed at the top of the docking post 21, the second teeth 29 corresponding to the first teeth 28.

[0031] As a preferred example of this utility model, in the adjustment mechanism, the docking post 21 can slide along the axis of the slot 22, thereby changing the distance between the two bases 1; the connecting cylinder 24 is connected to the slot 22 of the docking cylinder 2, and its inner cavity provides a guide channel for the vertical sliding of the locking post 26, ensuring that the locking post 26 can only move vertically; the second tooth 29 at the top of the docking post 21 and the first tooth 28 at the bottom of the locking post 26 have a tooth-meshing structure. When adjusting the distance between the bases 1, the locking post 26 is pulled upward to separate the first tooth 28 from the second tooth 29. At this time, the bases 1 can be pushed or pulled to change the insertion depth of the docking post 21; when the distance is adjusted to the correct position, the locking post 26 is released, and the locking post 26 moves downward under the external force, so that the first tooth 28 meshes with the second tooth 29 at the corresponding position. The relative sliding between the docking post 21 and the docking cylinder 2 is restricted by the mechanical meshing between the teeth, thereby achieving distance locking.

[0032] In the example of this application, a first spring 27 is sleeved on the outer wall of the locking post 26, and the two ends of the first spring 27 are fixedly connected to the side wall of the locking post 26 and the corresponding side wall of the connecting cylinder 24, respectively.

[0033] As a preferred example of this utility model, when the first spring 27 sleeved on the outer wall of the locking post 26 is in its natural state, it generates an upward elastic thrust on the locking post 26, so that the first tooth 28 at the bottom of the locking post 26 is always separated from the second tooth 29 at the top of the docking post 21.

[0034] In the example of this application, symmetrical limit grooves 23 are formed in the slot 22, and limit blocks 25 are symmetrically installed on the outer wall of the docking column 21. The limit blocks 25 are slidably connected to the limit grooves 23.

[0035] As a preferred example of this utility model, the limiting grooves 23 symmetrically opened on the inner wall of the slot 22 of the docking cylinder 2 and the limiting blocks 25 symmetrically installed on the outer wall of the docking post 21 form a sliding fit. The limiting blocks 25 are embedded in the limiting grooves 23 and can slide along the length of the limiting grooves 23. When adjusting the spacing of the base 1 and sliding the docking post 21 along the axis of the slot 22, the limiting blocks 25 always move synchronously within the limiting grooves 23. The side wall of the limiting grooves 23 restricts the movement of the limiting blocks 25 in the direction perpendicular to the axis of the slot 22, thereby restricting the movement trajectory of the docking post 21, ensuring that the docking post 21 always slides along the axis of the slot 22, maintaining the coaxiality of the docking post 21 and the docking cylinder 2, and preventing the docking post 21 from tilting or rotating.

[0036] In the example of this application, the positioning component includes a mounting bracket 3 fixedly connected to one side of the top of the docking cylinder 2. The top of the mounting bracket 3 has a movable groove, and a stop block 31 is movably installed in the movable groove. A second spring 32 is sleeved on one end of the stop block 31, and the two ends of the second spring 32 are fixedly connected to the side wall of the stop block 31 and the corresponding side wall of the mounting bracket 3, respectively.

[0037] As a preferred example of this utility model, when the second spring 32, which is sleeved on one end of the abutment 31, is in its natural state, it generates an elastic thrust on the abutment 31 toward the locking post 26, so that one end of the abutment 31 is always in close contact with the side wall of the locking post 26. When the locking post 26 is subjected to an upward external force and tends to move upward, the static friction between the abutment 31 and the locking post 26 prevents the locking post 26 from moving upward. At the same time, the abutment 31 continues to stick to the locking post 26 under the thrust of the second spring 32, and together with the teeth of the adjusting mechanism, it forms a double lock to prevent the locking post 26 from accidentally moving upward and causing the teeth to separate.

[0038] In the example of this application, the port of the abutment 31 is provided with a sloping groove 33, which corresponds to one end of the top of the locking post 26. The sloping surface of the sloping groove 33 extends downward from top to bottom along the height direction of the abutment 31.

[0039] As a preferred example of this utility model, the port of the abutment 31 facing the locking post 26 has an inclined groove 33, and the inclined surface of the inclined groove 33 forms an inclined contact with the top side wall of the locking post 26; when the operator needs to press down the locking post 26, the top end of the locking post 26 slides relative to the inclined surface of the inclined groove 33, which makes it easy for the operator to squeeze the locking post 26 to the bottom of the abutment 31 and be firmly limited by the abutment 31.

[0040] In the example of this application, the reinforcement component includes a first handle rod 15 fixedly connected to the top of one of the bases 1, a second handle rod 16 fixedly connected to the top of the other base 1, a limiting cylinder 17 fixedly connected to the top lateral port of the second handle rod 16, and the inner cavity of the limiting cylinder 17 being slidably connected to the top lateral port of the first handle rod 15.

[0041] As a preferred example of this utility model, in the reinforcement assembly, the first handle rod 15 and the second handle rod 16 are respectively fixed to the top of the two bases 1. The limiting cylinder 17 at the top of the second handle rod 16 has an inner cavity adapted to the lateral port at the top of the first handle rod 15. The lateral port of the first handle rod 15 is inserted into the inner cavity of the limiting cylinder 17 and can slide along the axial direction of the inner cavity. When the distance between the two bases 1 is adjusted, the lateral port of the first handle rod 15 slides synchronously in the inner cavity of the limiting cylinder 17 as the base 1 moves. The inner cavity sidewall of the limiting cylinder 17 restricts the offset of the lateral port of the first handle rod 15 in the direction perpendicular to the axis, ensuring that the first handle rod 15 and the second handle rod 16 always remain laterally aligned. At the same time, the connection structure formed by the first handle rod 15, the second handle rod 16 and the limiting cylinder 17 transmits the force of the two bases 1 to each other, disperses the pressure of the fabric roll weight on a single base 1, and prevents the base 1 from deforming or separating due to uneven force.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
