BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 The utility model is a structural schematic view. DETAILED DESCRIPTION

[0013] The utility model is described in detail below in combination with the drawings and specific embodiments.

[0014] Please refer to Figure 1 The utility model provides a kind of intermittent feeding device suitable for multiple products, including: module bottom plate 1, driving motor 2 being arranged on the module bottom plate 1, the output end of the driving motor 2 is connected with lead screw module 3, lifting cylinder module 4 is arranged on the movable end of the lead screw module 3, pawl mechanism is arranged on the output end of the lifting cylinder module 4, and flow channel plate 5 is arranged above the module bottom plate 1, product flow channel 51 is arranged on the flow channel plate 5 along the moving direction of the movable end of lead screw module 3, and the pawl mechanism moves in product flow channel 51.

[0015] In operation, the products are transported along the product flow channel 51. When the intermittent feeding device is driven, the lifting cylinder module 4 is driven to lift the pawl mechanism so that the pawl mechanism is in contact with the rear side of the products. Then the driving motor 2 is started to rotate the screw module 3, and the output end of the screw module 3 drives the lifting cylinder module 4 to move a certain distance in the feeding direction, so that the products are pushed forward by the pawl mechanism, and the products are moved forward by the same distance and then stopped. Then the lifting cylinder module 4 is reset, the pawl mechanism is lowered to a position below the bottom surface of the products, and the driving motor 2 is rotated in the direction to move the lifting cylinder module 4 and the pawl mechanism to the initial position to meet the needs of transporting the next group of products.

[0016] In some embodiments, the driving motor 2 is a servo motor, which has the characteristics of fast response, high precision, high stability, high torque, etc. The servo motor can quickly drive the screw module 3 to rotate, so that the lifting cylinder module 4 moves stably and reliably, and the transport distance can be adjusted according to different working needs to meet the needs of intermittent feeding of products in automatic production and processing.

[0017] In some embodiments, the lifting cylinder module 4 comprises a lifting seat 41 arranged on the moving end of the screw module 3, a driving cylinder 42 arranged on the lifting seat 41, a push block 43 arranged on the output end of the driving cylinder 42, a cam plate 44 movably arranged on the lifting seat 41, and a lifting block 45 connected with the cam plate 44, the pawl mechanism is arranged on the lifting block 45, the cam plate 44 is provided with a cam groove 441, one end of the cam groove 441 away from the driving cylinder 42 is lower than the other end close to the driving cylinder 42, both ends of the cam groove 441 are respectively provided with horizontal sections and are connected by inclined sections, and one end of the push block 43 is embedded in the cam groove 441.

[0018] In operation, the driving cylinder 42 is started to push the push block 43 out, so that one end of the push block 43 embedded in the cam groove 441 moves along the cam groove 441. When the driving cylinder 42 pushes the push block 43 out, one end of the push block 43 embedded in the cam groove 441 moves from the highest point of the cam groove 441 to the lowest point along the inclined section, so that the push block 43 moves to a relatively low position of the cam plate 44. Since the bottom of the push block 43 moves on the lifting seat 41, the push block 43 cooperates with the cam groove 441 to push the cam plate 44 upward, so as to lift the pawl mechanism connected with the lifting block 45, and the pawl mechanism moves to a height position in contact with the rear side of the products on the product flow channel 51, facilitating the pushing of the products and realizing the transport of the products.

[0019] When reset, the driving cylinder 42 resets, pulls the push block 43 back, so that the end of the push block 43 embedded in the cam groove 441 moves along the cam groove 441. When the driving cylinder 42 retracts the push block 43, the end of the push block 43 embedded in the cam groove 441 moves from the lowest point of the cam groove 441 to the highest point along the inclined section, so that the push block 43 moves to a position relatively high on the cam plate 44. Since the bottom of the push block 43 moves on the lifting seat 41, the cam plate 44 is driven downward by the cooperation of the push block 43 and the cam groove 441, so that the pawl mechanism connected with the lifting block 45 is moved downward, so that the pawl mechanism moves to a height position below the bottom surface of the product, avoiding collision or scratching with the product during reset.

[0020] In some embodiments, a plurality of output ends are provided on the lead screw module 3, and each output end is provided with a lifting cylinder module 4. By simultaneously controlling the movement of multiple lifting cylinder modules 4 through multiple output ends, the conveying requirements of multiple pawl mechanisms for products are met, so that the overall intermittent feeding device can synchronously intermittently convey multiple products, meeting the feeding requirements of different products and different processes.

[0021] In some embodiments, the movable ends of adjacent lifting cylinder modules 4 are connected by a connecting rod 46. The movable ends of adjacent lifting cylinder modules 4 are connected by the connecting rod 46, specifically, the two ends of the connecting rod 46 are connected to the push blocks 43 of adjacent lifting cylinder modules 4, so that the lifting driving state of adjacent lifting cylinder modules 4 for the pawl mechanism is stable and synchronized, thereby ensuring the stability and reliability of the feeding effect on the product.

[0022] In some embodiments, a plurality of support seats 11 are provided on the module bottom plate 1, and the flow channel plate 5 is arranged on the support seat 11. The flow channel plate 5 is supported and positioned by the support seat 11, meeting the assembly requirements of the flow channel plate 5, and ensuring that the flow channel plate 5 is located at a fixed distance above the lifting cylinder module 4, ensuring the contact effect on the product when the lifting cylinder module 4 drives the pawl mechanism to move up and down, and ensuring the stability of conveying the product.

[0023] In summary, the intermittent feeding device provided by the utility model has a flat and compact overall structure, saves installation space, effectively reduces production and manufacturing costs, and simultaneously, the pawl mechanism is lifted by the lifting cylinder module, so that the pawl mechanism contacts the rear side of the product, and the lead screw module is driven to move by the driving motor, thereby realizing intermittent conveying of the product, effectively controlling the conveying speed of the product or carrier, improving the overall production efficiency, and ensuring the accuracy and consistency of the feeding position, ensuring the stability of the product when feeding into the processing area, and improving the product processing quality.
