Description

Technical Field

[0001] This application relates to the technical field of cover production equipment, and more particularly to a cover stacking device. Background Technology

[0002] In the production of disposable paper and plastic lids, the application of automation technology has become key to improving production efficiency and reducing costs. To reduce manual intervention and improve operational efficiency, existing lid production lines and testing lines are usually equipped with automatic stacking devices at the back end to stack the lids one by one for subsequent whole-stack packing operations.

[0003] However, while existing paper cover stacking devices can achieve automatic stacking, they still have significant drawbacks. The stacking mechanism is typically located at the output end of the conveyor mechanism. When the paper cover enters the stacking mechanism from the conveyor, it mainly relies on its own inertia. This design has the following problems: when the paper cover enters the support platform of the stacking mechanism, if the trajectory is incorrect or it is affected by external interference (such as airflow, vibration, etc.), the paper cover may not be accurately aligned with the through-hole on the support platform. This will cause the lifting column to fail to smoothly lift the paper cover from the center, leading to problems such as paper cover flipping or even edge damage. These problems not only affect stacking efficiency but may also cause physical damage to the paper cover, increasing the defect rate and affecting overall production quality. Therefore, existing technologies still need improvement in terms of the stability and reliability of paper cover stacking. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a cover stacking device that can solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A cover stacking device, comprising:

[0007] A conveying mechanism for conveying the cover;

[0008] The stacking mechanism includes a top material module, a receiving platform, and a stacking module arranged from bottom to top. The receiving platform is connected to the output end of the conveying mechanism. The receiving platform is provided with a stop position aligned with the top material module. The top material module is used to lift the cover on the stop position to the stacking module for stacking.

[0009] The stacking mechanism further includes a blowing module, which is used to blow the cover body delivered to the receiving platform to the stopping position.

[0010] Optionally, the blowing module is located above the receiving platform and close to the conveying mechanism, and its blowing direction is tilted downwards towards the stopping position, so as to blow the cover at the front end of the receiving platform to the stopping position, while using the blowing pressure to press down the second cover on the receiving platform.

[0011] Optionally, the receiving platform is provided with two spaced-apart stop baffles, and a narrowed stop position is formed between the two stop baffles. The stop position gradually narrows from the side closer to the conveying mechanism to the side farther away from the conveying mechanism. The cover can enter the stop position from the flared end of the stop position and can be confined in the stop position by the two stop baffles.

[0012] Optionally, the distance between the stop baffle and the receiving platform is adjustable.

[0013] Optionally, the top of the top of the top of the top material module is provided with a detachable and replaceable top material head, which can enter the stop position and lift the cover.

[0014] Optionally, the stacking module includes a base plate, a support column, a stacking stop bar, and a check valve assembly. The bottom end of the support column is fixed to the receiving platform, and the top end supports the base plate, so that sufficient space is reserved between the base plate and the receiving platform to set the stopping position.

[0015] The base plate has a top material through hole in the center, and several stacking baffles are installed on the base plate and extend upward. The stacking baffles form a stacking space that communicates with the top material through hole.

[0016] Several of the aforementioned check valve components are mounted on the base plate around the top material through hole; the cover can pass through the check valve components unidirectionally from bottom to top, and through the support of the check valve components, the cover can be stacked in the material stacking space.

[0017] Optionally, at least one of the stacking blocks is provided with a pressing component, which is located above the check component. The pressing component can restrict the cover from jumping and flipping through the check component, and the cover can pass through the pressing component from bottom to top.

[0018] Optionally, the bottom end of the material stacking stop is connected to a first slide block, and the base plate is provided with a first guide rail extending in the radial direction along the top material through hole. The first slide block is slidably installed on the first guide rail, so that the spacing between each material stacking stop is adjustable.

[0019] The bottom end of the check valve assembly is connected to a second slide block, and the base plate is provided with a second guide rail extending radially along the top material through hole. The second slide block is slidably mounted on the second guide rail, so that the spacing between each check valve assembly is adjustable.

[0020] Optionally, the stacking module further includes an adjusting plate and a locking component. A guide post is provided on the first slide and the second slide respectively. The adjusting plate is provided with a plurality of guide holes corresponding one-to-one with the guide posts. The distance between the guide holes and the center of the top material through hole gradually changes, so that the guide post can be pushed to slide along the guide hole by rotating the adjusting plate, thereby synchronously adjusting the position of all the first slides and the second slides. The locking component is installed on the base plate and can release or lock the adjusting plate.

[0021] Optionally, the stacking stop includes three long rods and one short rod, with the central angle of the arc surface formed by the three long rods being greater than 180°, based on the central axis of the stacking space.

[0022] The beneficial effects of this application are: 1) Improved stacking stability: Through the guiding action of the blowing module, the cover can accurately enter the stopping position, avoiding the problem in the prior art where the cover cannot be aligned with the through hole due to incorrect trajectory or interference. This significantly improves the stability and success rate of cover stacking and reduces the risk of cover flipping or edge damage.

[0023] 2) Improve stacking efficiency: The introduction of the blowing module enables the cover to enter the stopping position quickly and accurately, reducing downtime or adjustment time caused by cover position deviation, thereby improving the overall stacking efficiency.

[0024] 3) Reduced defect rate: Through precise lid positioning and lifting operations, damage to the lid caused by physical impact during stacking is reduced, thereby reducing the defect rate and improving production quality.

[0025] 4) Low equipment cost: The blowing module uses air blowing to move the cover, which has the advantages of low equipment cost, easy implementation and easy installation. Attached Figure Description

[0043] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.

[0045] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the production of disposable paper and plastic lids, the application of automation technology has become key to improving production efficiency and reducing costs. To reduce manual intervention and improve operational efficiency, existing lid production lines and testing lines are usually equipped with automatic stacking devices at the back end to stack the lids one by one for subsequent whole-stack packing operations.

[0047] However, while existing paper cover stacking devices can achieve automatic stacking, they still have significant drawbacks. The stacking mechanism is typically located at the output end of the conveyor mechanism. When the paper cover enters the stacking mechanism from the conveyor, it mainly relies on its own inertia. This design has the following problems: when the paper cover enters the support platform of the stacking mechanism, if the trajectory is incorrect or it is affected by external interference (such as airflow, vibration, etc.), the paper cover may not be accurately aligned with the through-hole on the support platform. This will cause the lifting column to fail to smoothly lift the paper cover from the center, leading to problems such as paper cover flipping or even edge damage. These problems not only affect stacking efficiency but may also cause physical damage to the paper cover, increasing the defect rate and affecting overall production quality. Therefore, existing technologies still need improvement in terms of the stability and reliability of paper cover stacking.

[0048] To overcome the above technical problems, such as Figure 1-14 As shown, this embodiment provides a cover stacking device, including:

[0049] Conveying mechanism 1 is used to convey cover 4;

[0050] The stacking mechanism 2 includes a top material module 21, a receiving platform 22, and a stacking module 23 arranged from bottom to top. The receiving platform 22 is connected to the output end of the conveying mechanism 1. The receiving platform 22 is provided with a stopping position 221 aligned with the top material module 21. The top material module 21 is used to lift the cover 4 on the stopping position 221 to the stacking module 23 for stacking.

[0051] The stacking mechanism 2 further includes a blowing module 24, which is used to blow the cover 4, which is delivered to the receiving platform 22, to the stopping position 221.

[0052] In the application scenarios of the lid stacking device in this embodiment, it is generally used to stack products such as cup lids, bowl lids, or lunch box lids.

[0053] The conveying mechanism 1 is the starting part of the entire device, responsible for transporting the covers 4 from the production line or inspection line to the input end of the stacking mechanism 2. The conveying mechanism 1 typically consists of a conveyor belt, rollers, or other similar conveying devices, ensuring that the covers 4 can smoothly enter the stacking mechanism 2. The covers 4 fall onto the conveying mechanism 1 and are then transported one by one to the stacking mechanism 2 for stacking. To improve efficiency, the conveying mechanism 1 is equipped with multiple partitions, which divide the conveying mechanism 1 into multiple independent conveying channels. Correspondingly, a stacking mechanism 2 is installed at the end of each conveying channel, enabling multi-channel synchronous stacking operations and effectively improving stacking efficiency.

[0054] The top-loading module 21 is located at the bottom of the stacking mechanism 2 and is responsible for lifting the cover 4 on the stop position 221 to the stacking module 23. The top-loading module 21 is usually composed of a drive device such as a cylinder, hydraulic cylinder or electric push rod, and can move in the vertical direction.

[0055] The receiving platform 22 is located above the top material module 21 and is used to receive the cover 4 conveyed by the conveying mechanism 1. The receiving platform 22 is provided with a stopping position 221, which is aligned with the top material module 21 to ensure that the top material module 21 can accurately lift the cover 4.

[0056] The stacking module 23 is located above the receiving platform 22 and is used to receive the cover 4 lifted by the top material module 21 and stack it.

[0057] The blowing module 24 is used to blow the cover 4, which is conveyed to the receiving platform 22, to the stopping position 221. The blowing module 24 is usually composed of an air nozzle, a jet device or similar structure, and guides the cover 4 into the stopping position 221 by airflow.

[0058] During operation, the cover 4 is conveyed by the conveying mechanism 1 to the receiving platform 22 of the stacking mechanism 2. The blowing module 24 on the receiving platform 22 blows the cover 4 to the stopping position 221 via airflow, ensuring that the cover 4 is accurately aligned with the top-feeding module 21. The top-feeding module 21 moves upward under the action of the driving device, lifting the cover 4 on the stopping position 221 to the stacking module 23. The stacking module 23 receives the lifted cover 4 and gradually stacks it into a stack. After stacking is completed, the entire stack of cover 4 can be removed from the device for subsequent boxing operations.

[0059] The cover stacking device provided in this embodiment can achieve at least the following beneficial effects:

[0060] 1) Improved stacking stability: Through the guiding action of the blowing module 24, the cover 4 can accurately enter the stop position 221, avoiding the problem in the prior art where the cover 4 cannot be aligned with the through hole due to incorrect trajectory or interference. This significantly improves the stability and success rate of cover 4 stacking and reduces the risk of cover 4 flipping or edge damage.

[0061] 2) Improve stacking efficiency: The introduction of the blowing module 24 enables the cover 4 to enter the stop position 221 quickly and accurately, reducing downtime or adjustment time caused by the position deviation of the cover 4, thereby improving the overall stacking efficiency.

[0062] 3) Reduced defect rate: Through precise positioning and lifting of the cover 4, damage to the cover 4 caused by physical impact during the stacking process is reduced, thereby reducing the defect rate and improving production quality.

[0063] 4) Low equipment cost: The blowing module 24 uses air blowing to blow the cover 4, which has the advantages of low equipment cost, easy implementation and easy installation.

[0064] In one embodiment, reference is made to Figure 5-7 The blowing module 24 is located above the receiving platform 22 and close to the conveying mechanism 1, and its blowing direction is tilted downwards towards the stopping position 221, so as to blow the foremost cover 4 on the receiving platform 22 to the stopping position 221, while using the blowing pressure to press down the second cover 4 on the receiving platform 22.

[0065] The blowing module 24 typically consists of nozzles, jet devices, or similar airflow generators, capable of producing directional airflow. The nozzle layout and angle are optimized to ensure that the airflow accurately acts on the cover 4. The blowing direction is tilted downwards, which not only blows the foremost cover 4 to the stop position 221, but also applies a certain amount of pressure to the second cover 4 using the blowing pressure.

[0066] The covers 4 are sequentially fed into the receiving platform 22 via the conveying mechanism 1. The blowing module 24 applies an inclined pressure to the incoming covers 4, which has two components: a horizontal force and a vertical downward force. Specifically, the foremost cover 4 is unobstructed and can reach the stopping position 221 under the action of the horizontal force. The second cover 4 cannot move forward because it is blocked by the cover 4 in front, but it is pressed down by the vertical downward force applied by the blowing module 24. Under the action of this pressing force, the problem of the second cover 4 being lifted up and causing it to flip when the foremost cover 4 is lifted up can be avoided, thus ensuring the orderly entry of subsequent covers 4 and further improving the stability of the stack.

[0067] In one embodiment, reference is made to Figure 6The receiving platform 22 is provided with two spaced-apart stopping baffles 222, and the stopping position 221 is formed between the two stopping baffles 222. The stopping position 221 gradually narrows from the side closer to the conveying mechanism 1 to the side farther away from the conveying mechanism 1. The cover 4 can enter the stopping position 221 from the flared end of the stopping position 221 and can be restricted in the stopping position 221 by the two stopping baffles 222.

[0068] The flared end of the stopping position 221 is close to the conveying mechanism 1, while the constricted end is far from the conveying mechanism 1, causing the opening of the stopping position 221 to gradually narrow. The flared end design facilitates the entry of the cover 4 from the conveying mechanism 1 into the stopping position 221, reducing resistance and deviation when the cover 4 enters. The constricted end design ensures that the cover 4 can be precisely restrained in a predetermined position after entering the stopping position 221, preventing displacement or overturning of the cover 4 during stacking. Therefore, the stopping baffle 222 not only guides the cover 4 into the stopping position 221, but also restricts the position of the cover 4 during stacking, ensuring that the top-loading module 21 can accurately lift the cover 4.

[0069] In this embodiment, the constricted stop position 221 design ensures that the cover 4 can accurately enter and be confined within the stop position 221, avoiding stacking instability caused by trajectory deviation or external interference. This design significantly improves stacking stability and success rate. The guiding effect of the stop baffle 222 allows the cover 4 to enter the stop position 221 quickly and accurately, reducing the dwell time of the cover 4 on the receiving platform 22, thereby improving overall stacking efficiency.

[0070] In one embodiment, the distance between the stop baffle 222 and the receiving platform 22 is adjustable.

[0071] The stop baffle 222 is mounted on the receiving platform 22 via an adjustable connection structure, such as a slide rail, threaded adjustment device, or other similar mechanical structure. This design allows the operator to adjust the spacing between the two stop baffles 222 according to the dimensions of the cover 4.

[0072] Based on the actual size of the cover 4 on the production line, the operator can adjust the spacing between the stop baffles 222 accordingly, so that the flared end and the constricted end of the stop position 221 can adapt to the size of the cover 4, thus meeting the positioning requirements for covers 4 of various sizes.

[0073] In one embodiment, the top material module 21 includes a detachable and replaceable top material head 211, which can enter the stop position 221 and lift the cover 4.

[0074] The detachable design of the top head 211 allows operators to quickly replace the top head 211 with different specifications to adapt to the cover body 4 of different sizes or shapes.

[0075] In one embodiment, the stacking module 23 includes a base plate 231, a support column 2311, a stacking stop bar 233, and a check valve assembly 232. The bottom end of the support column 2311 is fixed to the receiving platform 22, and the top end supports the base plate 231, so that sufficient space is reserved between the base plate 231 and the receiving platform 22 to set the stopping position 221.

[0076] The base plate 231 has a top material through hole in the center, and a number of stacking baffles 233 are installed on the base plate 231 and extend upward. The stacking baffles 233 form a stacking space that communicates with the top material through hole.

[0077] Several of the aforementioned check valve components 232 are mounted on the base plate 231 around the top material through hole; the cover 4 can pass through the check valve components 232 from bottom to top in one direction, and with the support of the check valve components 232, the cover 4 can be stacked in the material stacking space.

[0078] The base plate 231 serves as a support platform for the stacking module 23. A top material through hole is provided in the center of the base plate 231, allowing the top material head 211 of the top material module 21 to pass through. The bottom end of the support column 2311 is fixed on the receiving platform 22, and the top end supports the base plate 231, ensuring that there is sufficient space between the base plate 231 and the receiving platform 22 to set up the stopping position 221.

[0079] Several stacking baffles 233 are installed on the base plate 231 and extend upward to form a stacking space. The stacking space is connected to the top material through hole to ensure that the top material module 21 can lift the cover 4 into the stacking space.

[0080] The check valve assembly 232 is mounted on the base plate 231 around the top material through hole, allowing the cover 4 to pass through unidirectionally from bottom to top. The check valve assembly 232 provides support after the cover 4 is lifted, preventing the stacked cover 4 from falling downwards.

[0081] During the stacking process, when the top-loading module 21 lifts the cover 4 to the stacking module 23, the cover 4 enters the stacking space through the top-loading through-hole. The check valve 232 allows the cover 4 to pass from bottom to top but prevents it from moving downwards, ensuring that the cover 4 can be stably stacked within the stacking space. The stacking space enclosed by the stacking baffle 233 restricts the horizontal displacement of the cover 4, ensuring that the cover 4 remains neat during stacking. The height design of the stacking baffle 233 should ensure that it can accommodate the stacking of multiple layers of cover 4. With multiple lifting operations of the top-loading module 21, the cover 4 enters the stacking space one by one and is supported by the check valve 232, eventually forming a neat stack of cover 4. After stacking is completed, the entire stack of cover 4 can be removed from the stacking module 23 for subsequent packing operations.

[0082] In this embodiment, the one-way design of the check valve component 232 ensures that the cover 4 can smoothly enter the stacking space, while preventing the stacked cover 4 from falling downwards, significantly improving the stability of the stack. The stacking baffle 233 restricts the horizontal displacement of the cover 4, ensuring the neatness and efficiency of the stacking process and reducing the adjustment time caused by the displacement of the cover 4.

[0083] In one embodiment, reference is made to Figure 13 The check valve assembly 232 includes a first fixed base 2322, a check valve lever 2323, and a return spring 2324. The first fixed base 2322 is fixedly installed, and the check valve lever 2323 is rotatably installed on the first fixed base 2322. One end of the return spring 2324 is connected to the check valve lever 2323, and the other end is connected to the first fixed base 2322. When the cover 4 moves upward, it pushes the check valve lever 2323 to rotate, thus passing upward through the check valve assembly 232. During this process, the return spring 2324 stretches and stores energy. After the cover 4 has completely passed the check valve lever 2323, the return spring 2324 releases its energy, causing the check valve lever 2323 to rotate and return to its original position, thereby preventing the cover 4 from falling back.

[0084] In one embodiment, reference is made to Figure 4 At least one of the stacking baffles 233 is provided with a pressing component 234, which is located above the check component 232. The pressing component 234 can restrict the cover 4 from jumping and flipping through the check component 232, and the cover 4 can pass through the pressing component 234 from bottom to top.

[0085] Specifically, when the first stacked cap is pushed upwards, there are no other caps applying pressure above it, making it prone to bouncing after passing the check valve 232. Furthermore, the degree of this bouncing is uncontrollable, making it difficult to prevent the cap from completely flipping over. Therefore, this solution includes a pressure assembly 234 above the pressure assembly 234. The limited space between the pressure assembly 234 and the check valve 232 restricts the space for the cap to bounce and flip, thus preventing the cap from flipping over.

[0086] For the settings of the pressure assembly 234, please refer to... Figure 14 The pressing assembly 234 includes a second fixed seat 2341, a pressing swing rod 2342, and a limiting protrusion 2343. The second fixed seat 2341 is fixed to the stacking stop 233. The pressing swing rod 2342 is rotatably mounted on the second fixed seat 2341. Under the natural gravity of the pressing swing rod 2342, it is in a horizontal state to extend into the stacking space and limit the upward bouncing cover 4. As the cover 4 is stacked upward, the cover 4 will push the pressing swing rod 2342 to rotate upward, so that the pressing swing rod 2342 gradually deviates from the stacking space.

[0087] The limiting protrusion 2343 is fixedly installed on one side of the second fixed base 2341 to limit the rotation angle of the pressure swing arm 2342, so that the pressure swing arm 2342 can rotate inward to a horizontal state under its own gravity in a natural state.

[0088] During implementation, in combination Figures 8-12 The bottom end of the material stacking baffle 233 is connected to a first slide block 2331. The base plate 231 is provided with a first guide rail 238 extending in the radial direction along the top material through hole. The first slide block 2331 is slidably installed on the first guide rail 238, so that the spacing between each material stacking baffle 233 is adjustable.

[0089] The bottom end of the check valve assembly 232 is connected to a second slide block 2321. The base plate 231 is provided with a second guide rail 239 extending radially along the top material through hole. The second slide block 2321 is slidably mounted on the second guide rail 239, so that the spacing between each check valve assembly 232 is adjustable.

[0090] Specifically, based on the size of the cover 4, the operator can adjust the spacing between the stacking baffles 233 to ensure that the stacking space can accommodate the cover 4 and maintain the neatness of the stack. Similarly, based on the size of the cover 4, the spacing between the check components 232 can be adjusted to ensure that the cover 4 can smoothly pass through the check components 232 into the stacking space, while preventing the stacked cover 4 from falling downwards.

[0091] The adjustable spacing between the stacking stop 233 and the check valve assembly 232 allows the device to adapt to different sizes of covers 4, eliminating the need to design or replace the stacking device separately for each size of cover 4, significantly improving the device's versatility and flexibility. By adjusting the spacing between the stacking stop 233 and the check valve assembly 232, the need to purchase new equipment due to changes in the size of the cover 4 is reduced, lowering equipment and maintenance costs.

[0092] In one embodiment, the stacking module 23 further includes an adjusting rotating plate 235 and a locking member 236. A guide post 237 is respectively provided on the first slide 2331 and the second slide 2321. The adjusting rotating plate 235 is provided with a plurality of guide holes 2351 corresponding one-to-one with the guide posts 237. The distance between the guide holes 2351 and the center of the top material through hole gradually changes, so that the rotation of the adjusting rotating plate 235 can push the guide posts 237 to slide along the guide holes 2351, thereby synchronously adjusting the positions of all the first slides 2331 and the second slides 2321. The locking member 236 is installed on the base plate 231, and the locking member 236 can release or lock the adjusting rotating plate 235.

[0093] The adjusting plate 235 is provided with a plurality of guide holes 2351. These guide holes 2351 correspond one-to-one with the guide posts 237 on the first slide block 2331 and the second slide block 2321. The distance between the guide holes 2351 and the center of the top material through hole gradually changes, so that the rotation of the adjusting plate 235 can push the guide posts 237 to slide along the radial direction of the guide holes 2351.

[0094] Guide posts 237 are respectively provided on the first slide block 2331 and the second slide block 2321, and the guide posts 237 cooperate with the guide holes 2351 on the adjusting plate 235.

[0095] The first slide block 2331 and the second slide block 2321 are respectively mounted on the first guide rail 238 and the second guide rail 239, and can slide along the guide rails.

[0096] Locking element 236 is mounted on base plate 231 to lock adjusting plate 235, ensuring that the adjusted slide position will not shift. Specifically, locking element 236 can be released or locked to allow for easy release when adjustment is needed and locking after adjustment.

[0097] When adjustment is needed, release the locking element 236 to allow the adjusting plate 235 to rotate freely. Then, rotate the adjusting plate 235, and the guide post 237 slides along the guide hole 2351, pushing the first slide block 2331 and the second slide block 2321 to slide along their respective guide rails. Since the distance between the guide hole 2351 and the center of the top material through hole gradually changes, rotating the adjusting plate 235 can simultaneously adjust the spacing of all the stacking stops 233 and the check valve assembly 232. Once the spacing of the stacking stops 233 and the check valve assembly 232 is adjusted to the appropriate position, the locking element 236 locks the adjusting plate 235, ensuring the slide block positions are fixed.

[0098] In this embodiment, by rotating the adjusting plate 235, the spacing between all the stacking stops 233 and the check valve assembly 232 can be adjusted simultaneously, significantly improving adjustment efficiency and reducing the time and complexity of adjusting them one by one. The gradient design of the guide hole 2351 ensures the uniformity and consistency of the slide movement, improves the adjustment accuracy, and ensures that the spacing between the stacking stops 233 and the check valve assembly 232 is uniform.

[0099] In one embodiment, the material stacking baffle 233 includes three long rods and one short rod, with the central angle of the arc surface formed by the three long rods being greater than 180°, based on the central axis of the material stacking space.

[0100] Three long rods form an arc with a central angle greater than 180°, creating a large support area that prevents the cover 4, which has been moved above the short rods, from tipping over. A short rod works in conjunction with the long rods; the shorter rod has a material outlet at its top, making it easy for workers to remove the stacked cover 4.

[0101] Preferably, the three long rods form an arc surface with a central angle of 185° to 195°.

[0102] In one embodiment, reference is made to Figure 3 It also includes a lifting mechanism 3, which is located on one side of the stacking stop bar 233. When the stacking reaches a set height, the lifting mechanism 3 can lift a stack of covers 4 to a height above the short bar. At this time, the stacking operation can continue below without stopping the machine. The workers can directly take out the stack of covers 4 that has been lifted from the gap on the side where the short bar is located.
