Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, and in particular to a conveying platform for a Shim machine. Background Technology

[0002] In the material conveying operations related to Shim machines (such as packaging materials like color boxes), traditional conveyor platforms suffer from several technical defects, making it difficult to meet the demands of efficient and high-quality production. Firstly, the conveyor belts of traditional platforms are mostly fixed installations, unable to be flexibly adjusted according to the location of glue leaks from glue guns during actual production. This causes glue to easily drip onto the conveyor belt and form hardened glue lumps. These hardened glue lumps not only scratch the surface of subsequently conveyed materials as the conveyor belt rotates, but also contaminate materials due to glue residue, affecting material quality. Simultaneously, the fixed conveyor belts lack effective tensioning and limiting structures, making them prone to deviation or slippage after long-term operation, leading to material misalignment and further increasing the risk of scratches and collisions. Secondly, the material limiting components of traditional conveyor platforms are usually of fixed specifications, unable to adapt to the conveying needs of materials with different widths. When the production scenario switches to different material specifications, the corresponding limiting components must be disassembled and replaced, a cumbersome and time-consuming operation that severely reduces production changeover efficiency and limits the equipment's adaptability to multi-category production scenarios. Furthermore, although some conveying platforms are equipped with limiting structures, it is difficult to keep the limiting guide rails parallel, or the limiting distance adjustment accuracy is insufficient. This causes the material to easily deviate during the conveying process. This not only causes friction and collision with the conveying platform frame, conveyor belt edges and other components, resulting in scratches and impacts on the material, but also increases the probability of the material being contaminated with residual adhesive stains and impurities from the conveying platform due to the large contact area between the material and the non-conveying area of ​​the conveying platform. This leads to problems such as DPO contamination, ultimately resulting in a lower finished product qualification rate, increased production rework costs, and an inability to meet the requirements of modern production for the stability, versatility and quality assurance capabilities of conveying equipment. Utility Model Content

[0003] The purpose of this invention is to provide a conveying platform for a Shim machine, which solves the above-mentioned problems.

[0004] This utility model is achieved through the following technical solution: A conveying platform for a Shim machine includes a conveying platform and multiple conveyor belts mounted on the conveying platform. The multiple conveyor belts can be independently adjusted in position to prevent glue droplets from falling onto the conveyor belts.

[0005] Furthermore, The conveying platform is also provided with an adjustment end. The adjustment mechanism includes an adjustment end and a fixed end. The fixed end is fixed below the conveying platform. An adjustment end corresponding to the number of multiple conveyor belts is provided on the fixed end, and each adjustment end corresponds to multiple conveyor belts. One end of the adjustment end is movably fitted with the fixed end, and the other end is located above the conveyor belt below the conveying platform and in contact with the conveyor belt.

[0006] Furthermore, The fixed end includes a mounting base and a crossbar. There are two mounting bases, which are respectively set on both sides of the bottom of one end of the conveying platform and are arranged opposite to each other. A crossbar parallel to the conveying platform is fixedly set between the two mounting bases.

[0007] Furthermore, The adjustment end includes a movable plate and a tensioning limit wheel. The movable plate is vertically and can move left and right on the crossbar. A tensioning limit wheel is provided on the side of the other end of the crossbar. The tensioning limit wheel is located above the conveyor belt and in contact with the corresponding conveyor belt. The conveyor belt is located between the two side walls of the tensioning limit wheel.

[0008] Furthermore, The upper surface of the conveying platform is also provided with a material limiting component, which includes a first limiting guide rail, a second limiting guide rail, a threaded seat, and a threaded rod. The first limiting guide rail is fixedly installed on one side of the conveying platform and parallel to the conveyor belt. The threaded seat is located on the side of the conveying platform opposite to the first limiting guide rail. A threaded rod passes through the threaded seat, and the end of the threaded rod facing the first limiting guide rail is vertically and movably connected to the second limiting guide rail.

[0009] Furthermore, The second limiting guide rail is parallel to the first limiting guide rail.

[0010] The beneficial effects of this utility model are: 1. The adjustment end under the conveyor platform uses a one-to-one linkage structure of "moving plate - tension limit wheel - conveyor belt" to flexibly adjust the lateral position of the conveyor belt according to the location of glue leakage from the glue gun. This ensures that the conveyor belt accurately avoids the leakage area, reducing the possibility of glue dripping onto the conveyor belt and forming hard glue blocks from the source. At the same time, the tension limit wheel wraps around the two side walls of the conveyor belt from above, preventing the conveyor belt from running off-track through lateral limiting force and providing appropriate longitudinal tension through rolling contact to prevent the conveyor belt from becoming loose and slipping. This eliminates material conveying misalignment caused by conveyor belt deviation or slippage, thereby reducing the problem of hard glue blocks scratching materials and glue stains contaminating materials, ensuring the stability of the conveying process and the surface quality of the materials.

[0011] 2. The material limiting component on the upper surface of the conveyor platform uses a fixed first limiting guide rail as a reference, and cooperates with a second limiting guide rail that can be adjusted via a threaded rod. Utilizing the threaded engagement between the threaded rod and the threaded seat, simply rotating the threaded rod will cause the second limiting guide rail to move laterally, and the second limiting guide rail will always remain parallel to the first limiting guide rail. This allows for precise adjustment of the distance between the two guide rails to accommodate materials of different widths. No replacement of the limiting components is required; operators can easily switch specifications through simple rotational adjustments, significantly improving the equipment's adaptability to multiple production scenarios and reducing the complexity and time cost of changeover operations.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0017] See Figures 1 to 3 : A conveying platform for a Shim machine includes a conveying platform 1 and multiple conveyor belts 2 mounted on the conveying platform 1. The multiple conveyor belts 2 can be independently adjusted in position to prevent glue droplets from falling onto the conveyor belts 2.

[0018] Furthermore, The conveying platform 1 is also provided with an adjustment end 31. The adjustment mechanism 3 includes an adjustment end 31 and a fixed end 30. The fixed end 30 is fixed below the conveying platform 1. An adjustment end 31 corresponding to the number of multiple conveyor belts 2 is provided on the fixed end 30, and each adjustment end 31 corresponds to multiple conveyor belts 2. One end of the adjustment end 31 is movably sleeved with the fixed end 30, and the other end is located above the conveyor belts 2 below the conveying platform 1 and is in contact with the conveyor belts 2.

[0019] Furthermore, The fixed end 30 includes a mounting base 301 and a crossbar 302. There are two mounting bases 301, which are respectively set on both sides of the bottom of one end of the conveyor platform 1 and are arranged opposite to each other. A crossbar 302 perpendicular to the moving direction of the conveyor belt 2 is fixedly set between the two mounting bases 301.

[0020] Two opposing mounting bases 301 provide balanced vertical support to the crossbar 302 from both sides, preventing the crossbar 302 from bending or swaying due to the weight of the adjusting end 31 and the limiting force on the conveyor belt 2, ensuring that the installation reference of the adjusting end 31 does not deviate. The crossbar 302 parallel to the conveying platform 1 sets a precise "lateral adjustment track" for the adjusting end 31, so that the subsequent left and right movement of the moving plate 310 is always along the direction perpendicular to the transmission of the conveyor belt 2, and the "oblique force" of the adjusting end 31 on the conveyor belt 2 will not occur due to the directional deviation of the crossbar 302, thereby avoiding new deviation problems caused by incorrect adjustment direction of the conveyor belt 2. At the same time, it provides a unified and stable mounting carrier for the independent adjustment of the three conveyor belts 2, preventing the adjustment of a single conveyor belt 2 from affecting the overall structural stability.

[0021] Furthermore, The adjusting end 31 includes a movable plate 310 and a tensioning limiting wheel 311. The movable plate 310 is vertically and can move left and right on the crossbar 302. The tensioning limiting wheel 311 is provided on the side of the other end of the crossbar 302. The tensioning limiting wheel 311 is located above the conveyor belt 2 and in contact with the corresponding conveyor belt 2. The conveyor belt 2 is located between the two side walls of the tensioning limiting wheel 311.

[0022] The tensioning limit wheel 311 is located above the conveyor belt 2 below the conveyor platform 1, and the conveyor belt 2 is between the two side walls of the tensioning limit wheel 311. The tensioning limit wheel 311 can limit the conveyor belt 2, and the tensioning limit wheel 311 can be moved together by moving the moving plate 310, so that the conveyor belt 2 can be moved together, thereby adjusting the position of the belt and preventing the glue dripping from the glue gun from falling onto the belt during glue dispensing.

[0023] The movable plate 310's ability to slide left and right allows for flexible adjustment of the lateral position of the tensioning limit wheel 311 based on the glue dripping location of the glue gun (determined through pre-production observation of the glue leakage area). This helps the conveyor belt 2 avoid the glue leakage area, reducing glue dripping onto the conveyor belt 2 at the source, thus preventing the formation of hard glue lumps and solving the problems of residual glue and scratches. The tensioning limit wheel 311 contacts and wraps around the two side walls of the conveyor belt 2 from above, generating a lateral limiting force on the conveyor belt 2 through the side walls, directly preventing the conveyor belt 2 from deviating due to uneven force. The rolling contact between the face wheel and the conveyor belt 2 provides appropriate longitudinal tension, preventing the conveyor belt 2 from becoming loose and slipping (slipping can easily cause material misalignment and increase the risk of scratches). In addition, the "one-to-one" corresponding design allows for individual adjustment of the three conveyor belts 2, which can accurately correct the deviation of each conveyor belt 2 and adjust the avoidance range of the conveyor belt 2 according to the glue leakage at different locations. This avoids the adjustment of a single conveyor belt 2 from affecting the normal operation of other conveyor belts 2, and greatly improves the adaptability and quality assurance capability of the conveying platform 1.

[0024] Furthermore, The upper surface of the conveying platform 1 is also provided with a material limiting component 4. The material limiting component 4 includes a first limiting guide rail 40, a second limiting guide rail 41, a threaded seat 42, and a threaded rod 43. The first limiting guide rail 40 is fixedly installed on one side of the conveying platform 1 and is parallel to the conveyor belt 2. The threaded seat 42 is set on the side of the conveying platform 1 opposite to the first limiting guide rail 40. The threaded rod 43 passes through the threaded seat 42. The end of the threaded rod 43 facing the first limiting guide rail 40 is vertically and movably connected to the second limiting guide rail 41.

[0025] By cooperating with the threaded rod 43 and the threaded seat 42, rotating the threaded rod 43 causes it to move within the threaded seat 42 towards the first limiting guide rail 40 or towards the second limiting guide rail 41, thereby adjusting the distance between the second limiting guide rail 41 and the first limiting guide rail 40 to limit materials of different widths and prevent the materials from shifting during the conveying process.

[0026] The first limiting guide rail 40 serves as a fixed reference, providing stable longitudinal positioning for the packaging box from one side. This prevents the packaging box from shifting to that side due to inertia during transport, and prevents the edge of the packaging box from rubbing against the rubber blocks on the edge of the conveyor platform 1 or conveyor belt 2, reducing the risk of scratches. The adjustable second limiting guide rail 41, through the cooperation of the threaded rod 43 and the threaded seat 42, enables precise adjustment of the distance between the two guide rails, adapting to packaging boxes of different widths. This allows for multi-specification production needs without replacing the guide rails. Furthermore, the vertical movable connection between the threaded rod 43 and the second limiting guide rail 41 prevents the second limiting guide rail 41 from twisting when the threaded rod 43 rotates. This ensures that the second limiting guide rail 41 always moves laterally, forming a "parallel clamping" limiting effect together with the first limiting guide rail 40. This ensures that the packaging box always moves along the center trajectory of the conveyor belt 2 during transport, reducing friction between the material and the non-contact area of ​​the conveyor belt 2, and further reducing the probability of DPO contamination.

[0027] Furthermore, The second limiting guide rail 41 is parallel to the first limiting guide rail 40.

[0028] The parallel guide rails provide uniform clamping force on both sides of the packaging box, preventing it from twisting or tilting due to excessive force on one side caused by guide rail tilting. This prevents uneven friction between the bottom of the packaging box and the surface of the conveyor belt 2 (uneven friction can easily cause local scratches), and also prevents the edge of the packaging box from getting stuck on the guide rail (getting stuck can easily cause material collisions and damage, such as the "collision damage" problem in the non-conforming product report in Document 1). On the other hand, the parallel guide rails ensure that the conveying path of the packaging box is completely aligned with the center of the conveyor belt 2, so that the bottom of the packaging box only contacts the three conveyor belts 2 and does not contact other areas of the conveyor platform 1. This reduces the contact area and avoids contact with any residual glue or impurities on the conveyor platform 1, further reducing the probability of residual glue and DPO dirt. Together with the design of the conveyor belt 2 to avoid glue leakage, this forms a "double quality guarantee", comprehensively solving the problems of scratches, residual glue, and dirt in the existing technology.

[0029] The method of using this utility model is as follows: A crossbar 302 parallel to the conveyor platform 1 is fixed between two opposing mounting seats 301 at the fixed end 30 below the conveyor platform 1. The movable plate 310 of the adjusting end 31 is vertically and slidably mounted on the crossbar 302. The tension limiting wheel 311 on the side of the movable plate 310 corresponds one-to-one with each conveyor belt 2 (the conveyor belt 2 is located between the two side walls of the tension limiting wheel 311). By pushing the movable plate 310, the tension limiting wheel 311 moves laterally synchronously. The contact between the tension limiting wheel 311 and the conveyor belt 2 will cause the conveyor belt 2 to adjust its position accordingly, accurately avoiding the glue leakage area and reducing the problem of water glue dripping onto the conveyor belt 2 to form hard glue blocks from the source. Next, the material limiting component 4 is adjusted: For the width of the material to be conveyed, the threaded rod 43 in the threaded seat 42 on the upper surface of the rotating conveyor platform 1, opposite to the first limiting guide rail 40, is used. Utilizing the threaded engagement between the threaded rod 43 and the threaded seat 42, the threaded rod 43 drives the second limiting guide rail 41, which is vertically connected to it, to move laterally. Because the second limiting guide rail 41 always remains parallel to the first limiting guide rail 40, which is fixed to one side of the conveyor platform 1 and parallel to the conveyor belt 2, the distance between the two guide rails can be precisely adjusted, providing suitable limiting space for subsequent material conveying. Then, the motor 5 is started, driving the gears and using a synchronous belt to rotate the conveyor rollers 6 at both ends of the conveyor platform 1, thereby moving the conveyor belt 2. During operation, the tensioning limiting wheel 311 applies a lateral limiting force to the conveyor belt 2 through its side walls to prevent the conveyor belt 2 from deviating, and provides appropriate longitudinal tension through rolling contact with the conveyor belt 2 to prevent the conveyor belt 2 from slipping. Simultaneously, the conveyor belt 2 gradually adjusts from an inclined state to move horizontally forward as it rotates, ensuring a stable conveying trajectory. Finally, the material is added. Under the clamping and limiting of the parallel first and second limit guide rails 41, the material is stably conveyed along the center trajectory of the horizontally forward conveyor belt 2. Its bottom only contacts multiple conveyor belts 2, reducing the probability of contact with residual adhesive stains and impurities in other areas of the conveying platform 1, effectively avoiding problems such as material scratches and DPO contamination, and achieving efficient and high-quality material conveying.
