Description

Technical Field

[0001] The utility model belongs to the technical field of feeding equipment, and in particular relates to a claw mechanism and a feeding device comprising the claw mechanism. Background Art

[0002] In the current automation field, due to the needs of automation, products or semi-finished products need to be oriented and regularly moved to specific processing positions, so various types of claw mechanisms with fixed pins are needed (such as patent number 201920484475.0). This type of claw mechanism with a fixed pin adopts a split design structure, which is convenient for disassembly and replacement, and the fixed pin can be installed in the corresponding inclined groove, and the movement of the inclined groove forms the up and down movement of the entire claw mechanism. However, this type of claw mechanism cannot achieve rapid resetting of the push part that contacts the product, and its structural stability and versatility are poor.

[0003] Based on this, it is urgent to improve the existing claw mechanism to solve the defects of the above-mentioned technology. Utility Model Content

[0004] One of the purposes of the utility model is to provide a claw mechanism capable of realizing automatic recovery in view of the shortcomings of the existing claw mechanism structure design, so as to solve the problem that the prior art cannot realize the rapid reset of the pushing part.

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

[0006] A pusher claw mechanism comprises a base, a rotating shaft, a reset member and a pusher claw, wherein the base comprises a fixed portion and a mounting portion connected to the fixed portion, and the pusher claw comprises a connecting portion, a resisting portion connected to one end of the connecting portion and a pushing portion connected to the other end of the connecting portion; the connecting portion is rotatably connected to the mounting portion via the rotating shaft, the resisting portion abuts against the fixed portion, and the pushing portion abuts against the fixed portion via the reset member.

[0007] The beneficial effects of the above technical solution of the utility model are:

[0008] The push claw mechanism of the utility model utilizes the abutment effect between the reset member and the pushing part, so that the push claw can automatically return to the initial state after completing the pushing action, thereby improving the structural stability and enabling the push claw mechanism to be applied to different scenarios, thereby solving the problems in the prior art that the push claw mechanism cannot realize the rapid reset of the pushing part in contact with the product, and has poor structural stability and poor versatility.

[0009] Furthermore, in order to optimize the pushing effect, the pushing part has a pushing surface and a contact surface connected to the pushed surface, the pushing surface and the contact surface form an angle α, and α<90°. Such a design enables the pushing part to better fit the surface of the object to be pushed during the pushing process, thereby reducing the pushing resistance and improving the pushing efficiency.

[0010] Furthermore, in order to improve the stability of the overall structure, the pusher part and the blocking part in the pusher claw mechanism of the utility model are perpendicular to the connecting part. This vertical arrangement can ensure that the pusher claw is evenly stressed during the action, reduce structural deformation and wear, and extend the service life.

[0011] In terms of the coordination between the base and the pusher claw, as a further improvement of the pusher claw mechanism of the utility model, a step is formed at the connection between the fixing part and the mounting part, the blocking part abuts against the step, one end of the reset part abuts against the step, and the other end of the reset part abuts against the pushing part. This design forms a stable triangular support structure between the blocking part, the reset part and the pushing part, further improving the stability of the pusher claw mechanism.

[0012] As a further improvement to the pusher claw mechanism of the present invention, the present invention selects the reset member as a spring or elastic steel sheet in consideration of cost and practicality. These materials have good elasticity and recovery performance, and can ensure that the pusher claw quickly returns to its initial state after the action is completed.

[0013] The second object of the utility model is to provide a feeding device, which includes a conveying mechanism, a driving mechanism, a reciprocating mechanism and a plurality of claw mechanisms that can realize automatic reset. The driving mechanism drives the reciprocating mechanism to drive the plurality of claw mechanisms to reciprocate in the flow channel of the conveying mechanism, thereby realizing continuous pushing of materials. This feeding device has the advantages of high pushing efficiency and good stability, and can be widely used in various automated production lines.

[0014] The beneficial effects of the above technical solution of the utility model are:

[0015] By designing a feeding device that matches the structure of an automatically recovering claw mechanism, the technical solution of the utility model realizes the continuous, efficient and stable pushing of materials, while improving the accuracy and safety of feeding, providing a strong guarantee for the stable operation of the automated production line.

[0016] In the specific implementation of the feeding device, as a further improvement of the feeding device in the utility model, the conveying mechanism includes a frame and a first conveying seat and a second conveying seat respectively mounted on the frame, the first conveying seat and the second conveying seat are arranged in parallel, and the flow channel is located between the first conveying seat and the second conveying seat. This design allows the material to be smoothly transmitted in the flow channel, and at the same time facilitates the claw mechanism to push the material.

[0017] In order to improve the accuracy of feeding, as a further improvement of the feeding device in the utility model, the conveying mechanism also includes a positioning structure, which includes a positioning seat arranged on the first conveying seat or the second conveying seat and a positioning block elastically connected to the positioning seat and used to abut against the product to be fed. Through the abutment between the positioning block and the product to be fed, the position of the product to be fed in the flow channel can be ensured to be accurate, thereby improving the accuracy of feeding.

[0018] In the realization of the reciprocating mechanism, as a further improvement of the feeding device in the utility model, the reciprocating mechanism includes a reciprocating plate arranged parallel to the bottom of the flow channel and a limit sensing block connected to the reciprocating plate, one end of the reciprocating plate is connected to the output end of the driving mechanism, and the claw mechanism is equidistantly arranged on the reciprocating plate. This design enables the reciprocating mechanism to stably drive the claw mechanism to reciprocate in the flow channel, and the limit sensing block can monitor the position of the reciprocating plate in real time to ensure accurate control of the movement process.

[0019] Furthermore, in order to improve the safety and stability of the feeding device, the feeding device of the utility model also includes a hydraulic buffer, which is arranged on the frame, and the position of the hydraulic buffer corresponds to the position of the limit sensing block. Through the buffering effect of the hydraulic buffer on the reciprocating plate, the impact and vibration of the reciprocating plate during the movement can be reduced, thereby improving the safety and stability of the feeding device.

[0062] Although the present application is disclosed as above in the form of a preferred embodiment, it is not intended to limit the claims. Any person skilled in the art may make several possible changes and modifications without departing from the concept of the present application. Therefore, the scope of protection of the present application shall be based on the scope defined by the claims of the present application.

[0063] The present invention will be described in further detail below in conjunction with specific implementations, but the implementations of the present invention are not limited thereto.

[0064] Implementation Method 1

[0065] like Figure 1-5As shown, a pusher claw mechanism comprises a base 1, a rotating shaft 2, a reset member 3 and a pusher claw 4. The base 1 comprises a fixing portion 11 and a mounting portion 12 connected to the fixing portion 11. The pusher claw 4 comprises a connecting portion 41, a blocking portion 42 connected to one end of the connecting portion 41 and a pushing portion 43 connected to the other end of the connecting portion 41. The connecting portion 41 is rotatably connected to the mounting portion 12 through the rotating shaft 2, the blocking portion 42 abuts against the fixing portion 11, and the pushing portion 43 abuts against the fixing portion 11 through the reset member 3. The base 1 is used to install the pusher claw 4 structure with an external device (the external device is a device for driving the pusher claw 4 structure and matching the pusher claw 4 structure for feeding), the mounting portion 12 provided on the base 1 is used to realize installation with an external device or connection with other structures, and the fixing portion 11 of the base 1 is used to provide support and limit for the pusher claw 4 in the pusher claw mechanism.

[0066] The working principle of the claw mechanism in this embodiment is as follows:

[0067] Pushing process of the pusher claw mechanism: when the pushing portion 43 of the pusher claw 4 is in contact with the material to be fed (in this application, the battery cell conveyed by the belt), the pushing portion 43 is subjected to backward resistance due to the obstruction of the material, causing the pusher claw 4 to rotate around the rotating shaft 2. At this time, the abutment relationship between the resisting portion 42 and the fixing portion 11 restricts the rotation of the pusher claw 4 to a certain extent, and at the same time, the reset member 3 begins to be stretched and deformed.

[0068] The reset process of the pusher mechanism: Since the pusher part 43 and the feed material are no longer in contact with each other, the material no longer exerts a blocking force on the pusher part 43. At this time, the reset member 3 begins to rebound under the restoring force generated by its own deformation, driving the pusher 4 to rotate around the rotating shaft 2 until the pusher part 43 returns to the position as shown in the figure. Figure 1 The initial position shown in the figure waits for the next pushing action. In this way, the pusher mechanism can realize the pushing and resetting functions of the material to be fed through the rotation of the pusher 4 and the resetting effect of the resetting member 3.

[0069] It is worth noting that in this embodiment, the arrangement of the resisting portion 42 against the fixing portion 11 can not only limit the rotation range of the pusher claw 4 to prevent it from over-rotating and damaging the reset member 3 or other structures, but also provide stability during the rotation of the pusher claw 4. At the same time, the arrangement of the reset member 3 enables the pusher claw 4 to automatically reset after completing the pushing action without additional operation, thereby improving the feeding efficiency.

[0070] Furthermore, the resisting portion 42 of the pusher claw mechanism in this embodiment abuts against the fixing portion 11, which can limit the rotation angle of the pusher claw 4 and prevent excessive rotation from causing structural damage or functional failure. The pushing portion 43 abuts against the fixing portion 11 through the reset member 3, so that the pusher claw 4 can quickly return to its initial state after the action is completed, ready for the next pushing operation.

[0071] It is worth noting that the above embodiments are only examples and do not constitute a limitation of the present invention. In practical applications, the structure and material of the claw mechanism can be adjusted and optimized according to specific needs to meet different application scenarios and performance requirements.

[0072] In addition, although only one structure and connection mode of the pusher claw mechanism are described in this embodiment, those skilled in the art should understand that, without departing from the basic principle and concept of the utility model, the pusher claw mechanism can also be improved and changed in various forms, such as adding a lubrication structure, adjusting the shape and size of the blocking portion 42, etc., to further improve its performance and use effect. At the same time, the pusher claw mechanism can also be used in conjunction with other types of feeding devices or automated production line equipment to meet a wider range of automated production needs. For example, the pusher claw mechanism can be applied to a battery feeding device, and through its stable reciprocating operation, the battery can be pushed continuously, efficiently, and stably, thereby improving production efficiency and product quality.

[0073] In summary, the claw mechanism provided in this embodiment has good elasticity and recovery performance, can ensure rapid recovery to the initial state after the action is completed, and is suitable for material pushing operations in various automated production lines.

[0074] Implementation Method 2

[0075] like Figure 1-5 As shown, different from the first embodiment, in order to further optimize the ability of the pusher mechanism to push materials, the pushing portion 43 has a pushing surface 431 and a contact surface 432 connected to the pushed surface 431, and the pushing surface 431 and the contact surface 432 form an angle α, and α is less than 90°. In a specific embodiment, the angle α is preferably 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, etc.

[0076] The working principle of the contact surface 432 is described as follows: after the pushing portion 43 pushes the material, the material will be guided to the non-pushing surface 431 side of the next pusher mechanism. At the same time, the pusher mechanism will move to the opposite side of the pushing surface 431 under the action of external force. Figure 4As shown in FIG. 4 , the contact surface 432 will come into contact with the material, and then the material's own gravity will compress the reset member 3, and then the pusher claw 4 will move clockwise around the rotating shaft 2 until the material can smoothly pass through the upper end of the pusher claw mechanism, and the material will move relative to the contact surface 432. After the material completely leaves the contact surface 432, under the action of the reset member 3, the pusher claw 4 will rotate counterclockwise around the rotating shaft 2 until it returns to the position shown in FIG. Figure 1 In this way, the pushing portion 43 of the pusher mechanism can guide the material to pass more smoothly, reduce the blocking and damage of the material during the pushing process, thereby improving the stability and efficiency of feeding.

[0077] It is worth noting that by adjusting the size of the α angle, the pushing effect of the pusher mechanism on the material can be further optimized. For example, when the α angle is small, the transition between the push surface 431 and the contact surface 432 is relatively gentle, which can reduce the impact force of the material during the pushing process and is conducive to protecting the material; when the α angle is large, the transition between the push surface 431 and the contact surface 432 is relatively steep, which can increase the thrust of the material during the pushing process and is conducive to pushing heavier materials. Therefore, in practical applications, a suitable α angle can be selected according to the characteristics of the material and the pushing requirements.

[0078] After a detailed explanation of the working principle of the contact surface 432, it can be understood that when the push part 43 performs the material pushing task, the design of its inclination angle can not only effectively reduce the resistance in the pushing process, thereby improving the pushing efficiency, but also assist the claw mechanism to smoothly reset after the material passes smoothly, thereby ensuring the accuracy of the subsequent pushing operation. It is particularly important to emphasize that the specific value of the angle α needs to be selected and adjusted in combination with the actual application scenario and material characteristics. If the angle is too small, the push part 43 may encounter too much resistance when pushing the material, thereby having an adverse effect on the pushing effect; conversely, if the angle is too large, it may weaken the effect of the contact surface 432 in assisting the reset, which is not conducive to the rapid reset of the claw mechanism. Therefore, the claw mechanism provided in this embodiment optimizes the material pushing process by adjusting the shape and structure of the push part 43, improves the pushing efficiency and accuracy, and is suitable for various automated production lines that require continuous and stable pushing of materials.

[0079] In this embodiment, the angle α is further preferably 45°, which not only optimizes the operating efficiency of the equipment, but also significantly enhances its stability and durability. Specifically, setting the angle α to 45° makes the internal structure layout of the equipment more reasonable, which is conducive to the efficient transmission of materials. At this angle, the contact surface 432 can rotate to a horizontal state more quickly, allowing the material to pass smoothly. In addition, the 45° angle α can effectively reduce the mechanical stress caused by angle problems, whether in the contact state or the reset state, thereby reducing the possibility of failure, thereby improving the overall performance and service life of the equipment.

[0080] Preferably, Figure 4 The resisting part 42 also has an inclined surface in the direction in which the contact surface 432 extends to the surroundings, and the inclination angle of the inclined surface is the same as that of the resisting part 42. The design principle is: when the contact surface 432 in this embodiment is working, the material needs to pass smoothly from the top of the claw mechanism. If there is a protruding part in the direction in which the contact surface 432 of the resisting part 42 extends, it will cause obstruction or collision to the material, thereby making the material transmission not smooth. Therefore, the resisting part 42 is also designed with an inclined surface in the direction in which the contact surface 432 extends, so that the material can pass smoothly and ensure the smoothness of the material transmission. At the same time, the inclination angle of the inclined surface is the same as that of the resisting part 42, which can ensure that the abutting relationship between the resisting part 42 and the fixed part 11 is stable, and avoid shaking or deviation during the material transmission process. This design not only optimizes the material transmission process, but also improves the stability and reliability of the claw mechanism, and further improves the performance of the entire automated production line.

[0081] Furthermore, in order to improve the stability of the pusher mechanism when pushing materials, a limit structure can be provided between the stopper 42 and the fixed part 11. The limit structure can limit the rotation range of the stopper 42 to prevent excessive rotation during the pushing process, thereby causing structural damage or functional failure. At the same time, the limit structure can also play a positioning role, ensuring that the pusher mechanism can accurately return to the initial position after each pushing operation, providing a stable basis for the next pushing operation.

[0082] It is worth noting that the specific form of the limiting structure can be designed according to actual needs. For example, the limiting structure can be realized by matching a convex block with a concave groove, or a spring or other elastic element can be arranged between the blocking portion 42 and the fixing portion 11 to provide appropriate resistance to limit the rotation range. Regardless of the form of the limiting structure, it is necessary to ensure that it can ensure the stability of the pusher claw mechanism while not affecting its normal pushing and resetting operations.

[0083] The other contents that are the same as those in Implementation 1 are not repeated in this implementation.

[0084] Implementation 3

[0085] like Figure 1-5 As shown, different from the first embodiment, in order to improve the stability of the overall structure, the pushing portion 43 and the blocking portion 42 in the pusher claw mechanism of the utility model are both perpendicular to the connecting portion 41. This vertical arrangement can ensure that the pusher claw 4 is evenly stressed during the action, reduce structural deformation and wear, and thus extend the service life of the pusher claw mechanism. At the same time, the vertical arrangement can also make the pusher claw mechanism more compact, reduce the occupied space, and facilitate the realization of high-density equipment layout in the automated production line.

[0086] The rest of the details that are the same as those in Implementation 1 are not described in detail in this implementation.

[0087] Implementation 4

[0088] like Figure 1-5 As shown, the difference from the first embodiment is that: in order to further improve the pusher claw mechanism of the utility model in terms of the cooperation between the base 1 and the pusher claw 4, a step 13 is formed at the connection between the fixing portion 11 and the mounting portion 12, the blocking portion 42 abuts against the step 13, one end of the reset member 3 abuts against the step 13, and the other end of the reset member 3 abuts against the pushing portion 43. This design forms a step 13 at the connection between the fixing portion 11 and the mounting portion 12, so that the blocking portion 42 can stably abut against the step 13, thereby enhancing the overall stability of the pusher claw mechanism. At the same time, one end of the reset member 3 abuts against the step 13, and the other end abuts against the pushing portion 43. Such a layout is not only convenient for installation and disassembly, but also ensures that the reset member 3 can fully exert its reset function during the action of the pusher claw 4.

[0089] In addition, the design of the step 13 also helps to improve the accuracy and reliability of the pusher mechanism. Since the abutment relationship between the stopper 42 and the step 13 is stable, shaking or deviation during the material pushing process can be effectively avoided, thereby improving the pushing accuracy. At the same time, the presence of the step 13 can also reduce the gap in the structure, improve the tightness of the entire mechanism, and further enhance its reliability.

[0090] It is worth noting that the shape and size of the step 13 need to be designed according to the actual application scenario and material properties to ensure that it can cooperate with the blocking portion 42 and the reset member 3.

[0091] The rest of the details that are the same as those in Implementation 1 are not described in detail in this implementation.

[0092] Implementation method 5

[0093] like Figure 1-5As shown, the difference from the first embodiment is that regarding the selection of the reset member 3, the present invention takes into account the cost and practicality, and selects the reset member 3 as a spring or an elastic steel sheet. The spring or elastic steel sheet as the reset member 3 has the advantages of simple structure, low cost, and easy acquisition. At the same time, they have good elasticity and recovery performance, which can ensure that the push claw mechanism can accurately reset to the initial position after each push operation, providing a stable basis for the next push operation. In addition, the spring and the elastic steel sheet also have high durability, which can maintain stable performance in long-term use and reduce maintenance costs.

[0094] In practical applications, a suitable spring or elastic steel sheet can be selected as the reset member 3 according to the specific requirements and working environment of the pusher claw mechanism. For example, for occasions where a large thrust is required, a spring with high stiffness and load-bearing capacity can be selected; and for occasions where a more compact and lightweight material is required, an elastic steel sheet can be selected as the reset member 3. By using a spring or elastic steel sheet as the reset member 3, the pusher claw mechanism provided in this embodiment not only has excellent pushing and reset performance, but also has the characteristics of low cost and easy maintenance, and is suitable for various automated production lines that require continuous and stable pushing of materials.

[0095] The rest of the details that are the same as those in Implementation 1 are not described in detail in this implementation.

[0096] Implementation 6

[0097] like Figure 1 As shown in FIG. 7 , a feeding device including a pusher mechanism 100 of any one of embodiments 1 to 5 includes a conveying mechanism 5, a driving mechanism 6 and a reciprocating mechanism 7. The driving mechanism 6 drives the reciprocating mechanism 7 to drive multiple pusher mechanisms 100 to reciprocate in the flow channel 51 of the conveying mechanism 5, thereby realizing continuous pushing of materials. This feeding device has the advantages of high pushing efficiency and good stability, and can be widely used in various automated production lines.

[0098] The working principle is as follows: the driving mechanism 6 provides power to drive the reciprocating mechanism 7 to reciprocate. The reciprocating mechanism 7 drives the multiple claw mechanisms 100 to move in the flow channel 51 of the conveying mechanism 5, thereby pushing the material. During the pushing process, the blocking portion 42 in the claw mechanism 100 contacts the material, pushing the material from one position in the flow channel 51 to another position. When the pushing is completed, the claw mechanism 100 automatically returns to the initial position through the action of the reset member 3, waiting for the next pushing operation.

[0099] The advantage of the feeding device is that, by adopting a plurality of claw mechanisms 100 that can realize automatic reset, continuous and stable pushing of materials is realized. At the same time, since the claw mechanism 100 has an automatic reset function, it can ensure that it can accurately reset to the initial position after each pushing operation, avoiding problems such as cylinder failure caused by material displacement. In addition, the feeding device also has the advantages of simple structure, convenient operation, low maintenance cost, etc., and is suitable for various automated production lines that need to continuously push materials.

[0100] In addition, the feeding device can also be optimized according to actual needs. For example, the shape, size and material of the pusher mechanism 100 can be adjusted according to the size, shape and weight of the material to ensure that it can firmly clamp and push the material. At the same time, the design of the conveying mechanism 5, the driving mechanism 6 and the reciprocating mechanism 7 can also be optimized to improve the stability and reliability of the entire feeding device.

[0101] Further, such as Figure 7 In order to further optimize the specific implementation of the feeding device, the conveying mechanism 5 also includes a frame 52 and a first conveying seat 53 and a second conveying seat 54 respectively mounted on the frame 52, the first conveying seat 53 and the second conveying seat 54 are arranged in parallel, and the flow channel 51 is located between the first conveying seat 53 and the second conveying seat 54. This design allows the material to be smoothly transported in the flow channel 51, and at the same time facilitates the claw mechanism 100 to push the material.

[0102] The rest of the details that are the same as those in Implementation 1 are not described in detail in this implementation.

[0103] Implementation 7

[0104] like Figure 1-8 As shown, different from the sixth embodiment, in order to improve the accuracy of feeding, the conveying mechanism 5 in this embodiment also includes a positioning structure 55, and the positioning structure 55 includes a positioning seat 541 arranged on the first conveying seat 53 or the second conveying seat 54 and a positioning block 542 elastically connected to the positioning seat 541 and used to abut the product to be fed. Through the abutment between the positioning block 542 and the product to be fed, the position of the product to be fed in the flow channel 51 can be ensured to be accurate, thereby improving the accuracy of feeding. In addition, the design of the positioning structure 55 can also reduce the shaking and displacement of the product to be fed during the transmission process to a certain extent, which helps to improve the stability and reliability of the entire feeding device.

[0105] Specifically, the design mechanism of the positioning structure 55 is as follows: the positioning seat 541 is fixedly arranged on the first conveying seat 53 or the second conveying seat 54, serving as the basic support of the positioning block 542. The positioning block 542 is connected to the positioning seat 541 by an elastic connector (such as a spring, an elastic sheet, etc.), so that the positioning block 542 can move elastically within a certain range. When the product to be fed enters the flow channel 51, the positioning block 542 will be squeezed by the product to be fed and move backward, and the elastic connector will be compressed. As the product to be fed continues to move forward, the positioning block 542 gradually moves forward under the restoring force of the elastic connector until it is closely abutted against the product to be fed. At this time, the positioning block 542 plays a role in fixing the position of the product to be fed, ensuring that it will not shake or move in the flow channel 51. When the claw mechanism 100 performs a pushing operation, the positioning block 542 will move forward together with the product to be fed, maintaining the abutment against it, thereby ensuring the stability and accuracy of the pushing process. When the product to be fed is pushed to the next station, the positioning block 542 will return to the initial position under the restoring force of the elastic connecting member, waiting for the entry of the next product to be fed.

[0106] It is worth noting that the shape, size, selection and parameter setting of the positioning block 542 and the positioning seat 541, etc., as well as the elastic connector, need to be reasonably designed according to the actual application scenario and the characteristics of the product to be fed to ensure that they can achieve the best positioning effect.

[0107] The rest of the details that are the same as those in Implementation 1 are not described in detail in this implementation.

[0108] Implementation 8

[0109] like Figure 1-9 As shown, in order to further improve the realization of the reciprocating operation of the feeding device of the utility model, as Fig. 9 The reciprocating mechanism 7 shown also includes a reciprocating plate 71 arranged parallel to the bottom of the flow channel 51 and a limit sensing block 72 connected to the reciprocating plate 71. One end of the reciprocating plate 71 is connected to the output end of the driving mechanism 6. The claw mechanism 100 is equidistantly arranged on the reciprocating plate 71.

[0110] Specifically, Fig. 9As shown, the driving mechanism 6 is connected to one end of the reciprocating plate 71 through the output end to provide power for the reciprocating motion of the reciprocating plate 71. Driven by the driving mechanism 6, the reciprocating plate 71 reciprocates along the bottom of the flow channel 51. The claw mechanism 100 is equidistantly arranged on the reciprocating plate 71, and performs a pushing operation in the flow channel 51 together with the movement of the reciprocating plate 71. The limit sensing block 72 is used to sense the position of the claw mechanism 100 to ensure that it can be accurately reset after the pushing is completed. When the claw mechanism 100 moves to a specific position, the limit sensing block 72 will send a signal, and the driving mechanism 6 will stop moving after receiving the signal and wait for the next pushing operation. This design not only improves the efficiency of feeding, but also ensures that each pushing operation can be completed accurately, avoiding failures caused by material displacement or inadequate pushing. In addition, the design also has the advantages of simple structure, easy maintenance and convenient operation, and is suitable for various automated production lines that require continuous pushing of materials.

[0111] Preferably, Fig. 9 As shown, the reciprocating mechanism 7 also includes a hydraulic buffer 8, which is arranged on the frame 52, and the position of the hydraulic buffer 8 corresponds to the position of the limit sensing block 72. The hydraulic buffer 8 is a device that uses liquid damping to achieve a buffering effect. It has a compact structure and good buffering effect, and is widely used in various occasions where it is necessary to reduce the impact and vibration of moving objects. In the feeding device, the hydraulic buffer 8 is installed on the frame 52, and its position corresponds to the limit sensing block 72. When the pusher mechanism 100 completes the pushing operation and moves to the position of the limit sensing block 72, the hydraulic buffer 8 starts to work, which can effectively reduce the impact speed of the pusher mechanism 100, so that it stops smoothly at a predetermined position, avoiding mechanical failure or material damage caused by sudden stop.

[0112] At the same time, the hydraulic buffer 8 can also absorb the energy generated during the movement, reduce mechanical vibration and noise, and improve the operating stability and working environment quality of the entire feeding device. In addition, the use of the hydraulic buffer 8 also extends the service life of the feeding device, reduces the frequency of maintenance and replacement of parts, and reduces production costs. Therefore, the introduction of the hydraulic buffer 8 not only optimizes the performance of the feeding device, but also improves its reliability and economy, providing a strong guarantee for the stable operation of the automated production line.

[0113] The above are only preferred implementations of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
