A sorting and stacking device for a synthetic resin tile production line

Abstract

This invention relates to the field of synthetic resin tile production technology, specifically to a sorting and stacking device for a synthetic resin tile production line. The device includes a base for supporting the synthetic resin tiles from the bottom up, a flattening roller positioned above the base, and an intermediate bag. The intermediate bag extends along the width of the synthetic resin tile and is located at one end of the tile, and can be filled with fluid. When the intermediate bag is filled with fluid, its volume increases, causing the end of the upper layer of synthetic resin tile to curl up. The flattening roller is fitted with a shape-matching part, which matches the shape of the synthetic resin tile during use. The flattening roller presses against the top of the upper layer of synthetic resin tile through the shape-matching part and can flatten the tile along its length from the curled-up end to the other, ultimately flattening the upper layer until it corresponds point-to-point with the lower layer, ensuring stable stress on the stacked tiles and thus guaranteeing the quality of the finished synthetic resin tile product.

Description

Technical Field

[0001] This invention relates to the field of synthetic resin tile production technology, and in particular to a sorting and stacking device for a synthetic resin tile production line. Background Technology

[0002] Synthetic resin tiles, as a new type of high-molecular polymer building material, are widely used in various building scenarios such as flat-to-slope roof conversions in development zones, farmers' markets, shopping malls, and residential communities due to their advantages such as light weight, high strength, waterproofing, moisture resistance, corrosion resistance, flame retardancy, sound insulation, and heat insulation. The integrity and standardization of its production process directly affect the final product quality. The stacking step, as a key node connecting production, warehousing, and logistics, not only affects the space utilization rate of subsequent warehousing and the convenience of logistics transportation, but also has a direct impact on the finished quality of the synthetic resin tiles.

[0003] Currently, the synthetic resin tile industry generally employs two methods in the stacking process: The first is manual stacking, which relies on operators at the end of the production line to manually handle, align, and stack the cooled synthetic resin tiles piece by piece. The second is simple mechanically assisted stacking, where mechanical structures replace some manual operations to improve stacking efficiency and neatness. For example, Chinese patent CN221395470U discloses a stacking device for resin tile production, which uses conveyor rollers and unidirectional block structures for auxiliary positioning, improving stacking efficiency and neatness, and is suitable for long-term large-scale production.

[0004] However, when stacking synthetic resin tiles, existing stacking devices cannot achieve point-to-point correspondence between the upper and lower layers of synthetic resin tiles because the tiles are mostly irregularly shaped. As the tiles are stacked, the error gradually accumulates. The lower layers of synthetic resin tiles bear greater local pressure and are more prone to deformation, which affects the quality of the finished product. Summary of the Invention

[0005] Therefore, it is necessary to provide a sorting and stacking device for synthetic resin tile production lines to address the problem that the current synthetic resin tile production and stacking process cannot achieve point-to-point correspondence, which affects the quality of finished products.

[0006] The above objectives are achieved through the following technical solutions:

[0007] A sorting and stacking device for a synthetic resin tile production line includes a base for supporting synthetic resin tiles from bottom to top, a rolling roller disposed above the base, and an intermediate bag disposed between adjacent layers of synthetic resin tiles during use.

[0008] The intermediate bag extends along the width of the synthetic resin tile and is located at the end of the synthetic resin tile, and can be filled with fluid; when the intermediate bag is filled with fluid, its volume increases, causing the end of the upper synthetic resin tile to curl up.

[0009] The rolling roller is fitted with a shape matching part, which matches the shape of the synthetic resin tile during use. The rolling roller presses on the top of the upper synthetic resin tile through the shape matching part, and can roll along the length of the synthetic resin tile from one end of the upper synthetic resin tile to the other end, and finally roll the upper synthetic resin tile until it corresponds point-to-point with the lower synthetic resin tile.

[0010] Furthermore, the fluid filling the interior of the intermediate bag is gas.

[0011] Furthermore, the shape matching part is a tubular structure, and the shape of its outer peripheral wall matches the outer shape of the synthetic resin tile after both ends are bent into circles along its own length direction.

[0012] Furthermore, the shape matching part and the rolling roller can be detachably connected, making it easy to replace shape matching parts with different outer peripheral wall shapes to adapt to different models of synthetic resin tiles.

[0013] Furthermore, the shape-matching part has a tubular double-layer structure, with the outer layer being a first capsule and the interior filled with fluid; when the first capsule comes into contact with the synthetic resin tile, under pressure, the first capsule deforms into a shape that matches the shape of the synthetic resin tile.

[0014] Furthermore, the base has a plate-like structure, and the plate surface is set horizontally.

[0015] Furthermore, a first cavity is formed inside the base; an opening communicating with the first cavity inside the base is provided at the top of the base; a second bladder that can be filled with fluid is provided inside the first cavity inside the base; when the second bladder is filled with fluid, it is exposed through the opening at the top of the base; when the synthetic resin tile is placed on top of the second bladder, the second bladder deforms under pressure to match the shape of the synthetic resin tile.

[0016] Furthermore, the sorting and stacking device for the synthetic resin tile production line also includes an iris mechanism located inside the base and above the second capsule. The iris mechanism forms a hole of a preset shape and a size that can be changed above the second capsule. The hole matches the shape of the synthetic resin tile to be placed. When the second capsule is filled with fluid, it is exposed through the hole.

[0017] Furthermore, the iris mechanism includes two first sliding plates and two second sliding plates located on the same horizontal plane. The first and second sliding plates are arranged alternately in the circumferential direction and connected end to end. The hole is formed by the inner edges of the two first sliding plates and the two second sliding plates. The first sliding plates can slide along the length direction of the synthetic resin tile, and the second sliding plates can slide along the length direction of the synthetic resin tile to change the size of the hole.

[0018] Furthermore, the iris mechanism also includes a first drive assembly for driving the first slide plate to slide along the length direction of the synthetic resin tile, and a second drive assembly for driving the second slide plate to slide along the width direction of the synthetic resin tile.

[0019] The beneficial effects of this invention are:

[0020] This invention relates to a sorting and stacking device for a synthetic resin tile production line. It comprises a flattening roller and an intermediate bag, with a shape-matching part fitted onto the flattening roller to match the top shape of the synthetic resin tile during use. During stacking, fluid is injected into the intermediate bag, increasing its volume and causing the upper layer of synthetic resin tile to curl up, serving as the starting point for subsequent flattening. The flattening roller is then pressed onto the top of the upper layer of synthetic resin tile via the shape-matching part, and subsequently flattened along the length of the synthetic resin tile from the curled-up end to the other, flattening the upper layer of synthetic resin tile until it aligns point-to-point with the lower layer, thereby ensuring stable stress on each layer of synthetic resin tile during stacking and thus guaranteeing the finished product quality of the synthetic resin tile.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] The component designations used in this document, such as "first" and "second," are merely for distinguishing the described objects and do not have any sequential or technical meaning. The terms "connection" and "linkage," unless otherwise specified, include both direct and indirect connections (linkages). In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description. They 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, and therefore should not be construed as limiting the invention.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] To meet the needs of building roofing, synthetic resin tiles are not regular flat panels, but have specific curved surfaces, overlapping edges and other irregular structures. This structure makes it impossible to achieve precise point-to-point correspondence between the upper and lower tiles during the stacking process, that is, there are slight deviations in the stress contact points of each tile.

[0040] Specifically, existing synthetic resin tiles are stacked to form a synthetic resin tile stack 5. For two adjacent synthetic resin tiles, because they have curved and straight sections, when the straight sections completely overlap, it inevitably leads to a gap between the curved sections, as shown in the image. Figure 1 The gap shown; and for the arc sections of two adjacent synthetic resin tiles to completely overlap, they must squeeze the straight sections to the left and right. At this time, the straight section located between the two arc sections is subjected to equal forces, both pointing towards its center. Under the combined action of these two forces, the straight section will inevitably bulge upward, causing the upper and lower straight sections to be unable to make complete contact.

[0041] Moreover, this imprecise alignment leads to a continuous accumulation of stacking errors as the stacking height increases. The bottom tiles, as the load-bearing foundation of the entire stack, must support the weight of all the tiles above them. However, because the upper and lower tiles cannot be precisely aligned, the weight of the upper tiles cannot be evenly distributed to the entire load-bearing surface of the bottom tiles. Instead, it is concentrated at a limited number of contact points, resulting in a significant increase in localized pressure on the bottom tiles. At the same time, although synthetic resin tiles possess a certain strength, long-term exposure to uneven, concentrated pressure will gradually cause plastic deformation. This deformation not only affects the appearance and structural integrity of individual tiles but also further exacerbates the stacking deviation of the upper tiles, creating a vicious cycle of error accumulation—uneven pressure—intensified deformation. Ultimately, this affects the finished quality of the entire stack of synthetic resin tiles and may even render some tiles unusable due to deformation exceeding the acceptable range.

[0042] Based on this, the present invention provides a sorting and stacking device for a synthetic resin tile production line, which is particularly suitable for stacking synthetic resin tiles. Of course, it is also suitable for stacking other irregularly shaped tile structures.

[0043] Specifically, refer to Figures 2 to 12 As shown, the synthetic resin tile production line uses a sorting and stacking device comprising a base 1, a rolling roller 2, and an intermediate bag 3. After manufacturing, the synthetic resin tiles are placed horizontally on top of the base 1, allowing the base 1 to support the tiles from the bottom up. Taking a rectangular synthetic resin tile as an example, the intermediate bag 3 is positioned between adjacent layers of synthetic resin tiles, extending horizontally along the width of the tiles and located at the ends. The intermediate bag 3 can be filled with fluid to change its volume, facilitating the lifting of the upper layer's end, making it a starting point for subsequent rolling. Alternatively, the intermediate bag 3 can be removed from between adjacent layers to ensure that the lifted end of the upper layer overlaps with the lower layer's end during the subsequent rolling process of the rolling roller 2. The cross-sectional shape of the intermediate bag 3 can be spindle-shaped, i.e., wide in the middle and pointed at both ends.

[0044] The rolling roller 2 is positioned above the base 1 and extends horizontally along the width of the synthetic resin tile. A shape matching part 4 is fitted onto the rolling roller 2. During use, the shape matching part 4 matches the top shape of the synthetic resin tile, facilitating subsequent rolling operations. The rolling roller 2 can move vertically and press against the top of the upper synthetic resin tile through the shape matching part 4. It can also move horizontally along the length of the synthetic resin tile, simultaneously driving the shape matching part 4 to roll from one end of the upper synthetic resin tile that is raised to the other end, rolling the upper synthetic resin tile until it corresponds point-to-point with the lower synthetic resin tile.

[0045] During the stacking process, the first layer of synthetic resin tiles is first placed horizontally on top of the base 1. Then, the intermediate bag 3 is moved to the end of the first layer of synthetic resin tiles and fluid is injected into it to increase its volume, which is then maintained. Next, the second layer of synthetic resin tiles is placed horizontally on top of the first layer. Because the intermediate bag 3 has expanded, the end of the second layer of synthetic resin tiles will slightly tilt upwards under the support of the intermediate bag 3. Then, the rolling roller 2 is moved to directly above the tilted end of the second layer of synthetic resin tiles, and then the rolling roller 2 is moved downwards to form a shape. The shape matching part 4 is pressed against the raised end of the second layer of synthetic resin tile. Under the pressure of the shape matching part 4, the raised end of the second layer of synthetic resin tile will move slightly first until the ends of the first layer of synthetic resin tile and the second layer of synthetic resin tile are aligned point-to-point. Then, the shape matching part 4 is driven to move and roll from one raised end of the upper layer of synthetic resin tile to the other end to achieve a flattening motion. Since the ends of the first layer of synthetic resin tile and the second layer of synthetic resin tile are already aligned point-to-point, under the flattening of the shape matching part 4, the subsequent second layer of synthetic resin tile gradually aligns point-to-point with the first layer of synthetic resin tile.

[0046] When the shape matching part 4 moves to the other end of the second layer of synthetic resin tile, it drives the shape matching part 4 to perform a flattening motion in the opposite direction to enhance the point-to-point correspondence between the first layer of synthetic resin tile and the second layer of synthetic resin tile. When the shape matching part 4 is about to move to the position close to the middle bag 3, gas is continued to be filled into the middle bag 3 to further increase its volume, and then the volume of the device is kept constant. As the middle bag 3 expands, the gap between the ends of the first layer of synthetic resin tile and the second layer of synthetic resin tile increases slightly. At this time, the middle bag 3 can be easily removed from the ends of the first layer of synthetic resin tile and the second layer of synthetic resin tile. Since the shape matching part 4 is located close to the middle bag 3, the removal of the middle bag 3 will not cause the first layer of synthetic resin tile and the second layer of synthetic resin tile to shift under the pressure of the shape matching part 4, and thus will not affect the point-to-point correspondence between the first layer of synthetic resin tile and the second layer of synthetic resin tile. After the middle bag 3 is removed, as the shape matching part 4 flattens, the raised end of the second layer of synthetic resin tile overlaps with the first layer of synthetic resin tile.

[0047] Then repeat the above process until the synthetic resin tiles are stacked into a predetermined number of layers (5).

[0048] During the process of stacking synthetic resin tiles into a preset number of layers (stack 5), this device ensures precise point-to-point alignment between each layer of synthetic resin tiles and the layer below. After the upper and lower tiles achieve full contact and uniform fit, the load from the upper layer can be evenly transferred to the lower layer along the tile's stress surface, preventing excessive local pressure and plastic deformation. Simultaneously, precise alignment prevents the offset error from amplifying with increasing stacking height, maintaining the structural stability and stress balance of the entire stack. This ensures that each layer of tiles remains under stable stress throughout the stacking process, effectively suppressing quality defects such as deformation and warping, thereby consistently guaranteeing the finished appearance and performance of the synthetic resin tiles.

[0049] In one embodiment, the fluid filling the intermediate bag 3 is gas. Because gas is compressible, it can shrink in volume under pressure, adapting to changes in position and gaps during stacking and flattening. When the flattening roller 2 drives the shape matching part 4 to roll along the surface of the upper synthetic resin tile, under the uniform downward pressure of the flattening roller 2 and the shape matching part 4, the intermediate bag 3 can be gradually compressed with changes in pressure, its volume adaptively decreasing. This eliminates the local gaps between the upper and lower synthetic resin tiles caused by the bag support, resulting in a more complete and tighter contact between the two layers of tiles. Based on this, the upper synthetic resin tile can be more accurately guided to a preset position under pressure and flattening action, effectively reducing alignment deviation and significantly improving the accuracy and stability of point-to-point alignment between the upper and lower synthetic resin tiles.

[0050] In one embodiment, the shape matching part 4 is a tubular structure, and the shape of its outer peripheral wall matches the outer shape of the synthetic resin tile after both ends are bent into circles along its length.

[0051] When the rolling roller 2 drives the shape matching part 4 to roll on the upper synthetic resin tile, the upper synthetic resin tile will gradually move to correspond point-to-point with the lower synthetic resin tile under the shape restriction of the shape matching part 4.

[0052] In a further embodiment, to improve applicability, the shape matching part 4 and the rolling roller 2 are detachably connected, making it easy to replace the shape matching part 4 with different outer peripheral wall shapes to adapt to different models of synthetic resin tiles.

[0053] Specifically, clamping plates are vertically provided at both ends of the rolling roller 2. The clamping plates can be detachably connected to the rolling roller 2 by fasteners such as bolts. The two ends of the shape matching part 4 are clamped by the two clamping plates, thereby realizing a detachable connection between the shape matching part 4 and the rolling roller 2.

[0054] In other embodiments, the shape matching part 4 is a tubular double-layer structure, with the outer layer being a first capsule and the interior filled with fluid.

[0055] When the rolling roller 2 drives the shape matching part 4 to roll on the upper synthetic resin tile, the first bladder comes into contact with the synthetic resin tile. Under pressure, the first bladder deforms into a shape that matches the shape of the synthetic resin tile. Under the shape restriction of the shape matching part 4, the upper synthetic resin tile will gradually move to correspond point-to-point with the lower synthetic resin tile.

[0056] In one embodiment, the base 1 is a plate-shaped structure with the plate surface set horizontally. After the synthetic resin tile is manufactured, it is placed on top of the base 1 so that the base 1 can horizontally support the synthetic resin tile from the bottom up.

[0057] In a further embodiment, to reduce the deformation of the bottom layer of synthetic resin tile, a first cavity 104 is formed inside the base 1; the base 1 includes a horizontally arranged base plate 101, and a first top plate 102 is arranged parallel to the top of the base plate 101. The base plate 101 and the first top plate 102 have the same shape and size, and are enclosed on all sides by vertical sealing plates. A partition 103 is vertically arranged between the base plate 101 and the first top plate 102. The number of partitions 103 is two or four. When there are two partitions 103, both partitions 103 extend along the width direction of the synthetic resin tile to contact the sealing plate, and are spaced apart along the length direction of the synthetic resin tile. The first cavity 104 is formed by the bottom plate 101, the first top plate 102, the sealing plate, and the two partitions 103. When there are four partitions 103, the four partitions 103 form a preset shape, such as a rectangle. The first cavity 104 is formed by the bottom plate 101, the first top plate 102, and the four partitions 103. The top of the base 1 has an opening that communicates with the first cavity 104 inside the base 1. The opening is specifically opened on the first top plate 102 and is located in the middle of the first top plate 102. The first cavity 104 inside the base 1 is provided with a second bladder 6 that can be filled with fluid.

[0058] When the second bladder 6 is filled with fluid, it is exposed through the top opening of the base 1. When the synthetic resin tile is placed on top of the second bladder 6, the second bladder 6 will deform under pressure to match the shape of the synthetic resin tile. Thus, by fully fitting with the bottom layer of synthetic resin tiles, the overall support stability of the synthetic resin tile stack 5 can be effectively improved, and the deformation of the bottom layer of synthetic resin tiles can be reduced.

[0059] In a further embodiment, to improve applicability and ensure complete adhesion between the second capsule 6 and the bottommost synthetic resin tile, the sorting and stacking device for the synthetic resin tile production line further includes an iris mechanism 7 disposed within the base 1 and above the second capsule 6; a second top plate 105 is disposed parallel to the first top plate 102 directly above it, and the shape and size of the second top plate 105 are the same as those of the first top plate 102; a sealing plate extends upward to contact the side wall of the second top plate 105, thereby sealing the circumferential gap between the first top plate 102 and the second top plate 105, and a second cavity 106 is formed between the first top plate 102 and the second top plate 105, and the iris mechanism 7 is specifically disposed within the second cavity 106. The iris mechanism 7 has a pre-defined and variable-sized hole above the second capsule 6, the shape of which matches the shape of the synthetic resin tile to be placed, and it protrudes through the hole when the second capsule 6 is filled with fluid.

[0060] Therefore, when classifying and stacking synthetic resin tiles, the size of the holes can be adjusted by the iris mechanism 7 according to the shape of the tiles to be placed, effectively constraining the exposed shape of the second bladder 6 and ensuring that the area protruding from the hole perfectly matches the shape of the tile. On the one hand, this ensures the geometric consistency between the support part of the second bladder 6 and the contact surface of the tile, avoiding tile offset due to support misalignment; on the other hand, it ensures that the support range of the second bladder 6 accurately covers the key stress area of ​​the tile, ensuring that the synthetic resin tiles maintain a stable horizontal posture and fit during stacking and subsequent transportation, thereby achieving precise point-to-point correspondence during stacking.

[0061] In one embodiment, the iris mechanism 7 is configured to include two first sliding plates 701 and two second sliding plates 702 located on the same horizontal plane. The first sliding plates 701 and the second sliding plates 702 are both rectangular in shape, and the short side of the first sliding plate 701 coincides with the long side of the adjacent second sliding plate 702, and the long side of the first sliding plate 701 coincides with the short side of the other second sliding plate 702. The first sliding plates 701 and the second sliding plates 702 are both disposed in the second cavity 106 and are arranged alternately along the circumference and connected end to end. The hole is formed by the inner edges of the two first sliding plates 701 and the two second sliding plates 702. The first sliding plate 701 can slide along the length direction of the synthetic resin tile, and the second sliding plate 702 can slide along the length direction of the synthetic resin tile to change the size of the hole.

[0062] In one embodiment, to enable the first sliding plate 701 and the second sliding plate 702 to slide along a preset direction, the first sliding plate 701 and the first top plate 102 and / or the second top plate 105 can be connected by a first sliding strip and a first sliding groove, and both the first sliding strip and the first sliding groove extend along the length direction of the synthetic resin tile to facilitate the sliding of the first sliding plate 701 along the length direction of the synthetic resin tile; the second sliding plate 702 and the first top plate 102 and / or the second top plate 105 can be connected by a second sliding strip and a second sliding groove, and both the second sliding strip and the second sliding groove extend along the width direction of the synthetic resin tile to facilitate the sliding of the second sliding plate 702 along the width direction of the synthetic resin tile.

[0063] Specifically, the size of the hole can be changed by manually pushing the first sliding plate 701 and the second sliding plate 702.

[0064] It is understandable that, in order to reduce the friction when the first slide plate 701 and the second slide plate 702 slide, both the first slide bar and the second slide bar can be replaced with rolling elements, such as balls or rollers, so that the friction mode of the first slide plate 701 and the second slide plate 702 changes from sliding friction to rolling friction.

[0065] In other embodiments, to enable the first slide plate 701 and the second slide plate 702 to slide along a preset direction, the iris mechanism 7 may also be configured to include a first driving component for driving the first slide plate 701 to slide along the length direction of the synthetic resin tile, and a second driving component for driving the second slide plate 702 to slide along the width direction of the synthetic resin tile.

[0066] Specifically, the first drive assembly can be configured to include two first drive cylinders, the output shafts of which extend along the length direction of the synthetic resin tile and are respectively disposed on the sidewalls of the two first slide plates 701, facilitating the sliding of the two first slide plates 701 along the length direction of the synthetic resin tile. Similarly, the second drive assembly can be configured to include two second drive cylinders, the output shafts of which extend along the width direction of the synthetic resin tile and are respectively disposed on the sidewalls of the two second slide plates 702, facilitating the sliding of the two second slide plates 702 along the width direction of the synthetic resin tile.

[0067] It is understandable that both the first and second drive cylinders can be set as any one of hydraulic cylinders, pneumatic cylinders, or electric cylinders.

[0068] In one embodiment, to enable the rolling roller 2 to slide in both vertical and horizontal directions, four uprights 8 are vertically provided on the top of the base 1. The four uprights 8 are distributed in a rectangular shape, with the sides of the rectangle corresponding to and parallel to the rectangular sides of the synthetic resin tile. A first lead screw 9 is vertically and rotatably provided in each upright 8. A first crossbar 10 is simultaneously slidably sleeved on each of the two first lead screws 9 arranged along the length of the synthetic resin tile. The first crossbar 10 is a strip structure, horizontally arranged, and has a U-shaped cross-section. The opening of the first crossbar 10 faces horizontally toward the synthetic resin tile. A first ball screw nut 11 is fixedly provided in the opening of the first crossbar 10, and the first ball screw nut 11 is drivenly sleeved on the first lead screw 9. A second lead screw 12 is provided parallel to and rotatably in the opening of each first crossbeam 10; a first slider 13 is provided at both ends of the rolling roller 2. The first slider 13 is inserted into the opening of the first crossbeam 10 and can slide along the extension direction of the first crossbeam 10. A second ball screw nut 14 is provided inside each first slider 13. The second ball screw nut 14 is driven and sleeved on the second lead screw 12.

[0069] To facilitate the provision of driving force for the rotation of the first lead screw 9, a first drive motor 15 is provided on the top of each upright 8. The motor shaft of the first drive motor 15 is fixedly connected to the first lead screw 9, which facilitates the rotation of the first lead screw 9.

[0070] To facilitate the provision of driving force for the rotation of the second lead screw 12, a second drive motor 16 is provided at the top of each first crossbeam 10. A first pulley 17 is fixedly sleeved on the motor shaft of the second drive motor 16, and a second pulley is fixedly sleeved on the second lead screw 12. A first transmission belt 18 is connected between the first pulley 17 and the second pulley to facilitate the rotation of the second lead screw 12.

[0071] It is understandable that the first pulley 17 and the second pulley can be replaced with sprockets, and the first transmission belt 18 can be replaced with a chain, so as to achieve the same function of driving the second lead screw 12 to rotate.

[0072] During use, the first drive motor 15 is started, which drives the first lead screw 9 to rotate. The first lead screw 9, through the transmission cooperation with the first ball screw nut 11, drives the first crossbeam 10 to slide in the vertical direction. The first crossbeam 10, through the cooperation with the first slider 13, drives the rolling roller 2 to slide in the vertical direction.

[0073] Start the second drive motor 16, which drives the first pulley 17 to rotate. The first pulley 17 drives the second pulley to rotate synchronously through the first transmission belt 18. The second pulley drives the second lead screw 12 to rotate synchronously. The second lead screw 12 drives the first slider 13 to slide along the first crossbeam 10 synchronously through the transmission cooperation between the second ball screw nut 14 and the first slider 13 drives the rolling roller 2 to slide in the horizontal direction.
