Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, in particular to an automatic feeding and conveying device for a plastic bottom sheet for a carton handle and a method thereof. Background Art

[0002] In order to facilitate the carrying of gift boxes, the gift boxes are equipped with handles through the bottom plate. Therefore, during the processing, the handles through the bottom plate are assembled and installed with the gift boxes to facilitate the carrying and transportation of the gift boxes. However, during the use of the handles, in order to ensure the stability and firmness of the handles and prevent the handles from falling off, it is necessary to install a plastic bottom sheet that matches the handles inside the carton to prevent the handles from falling off and being loose. Therefore, it is particularly important to transport the plastic bottom sheet to the handle installation station.

[0003] A Chinese patent with application number CN202122970877.1 discloses a pushing device for the handle bottom plate of a matching box. The above patent document gradually pushes the handle bottom plate through the reciprocating movement of the pushing plate, replacing the existing method of directly sending the handle bottom plate to the bottom of the installation station, saving the pushing stroke of the handle bottom plate and maintaining its stable pushing.

[0004] The Chinese patent application number CN201520506483.2 discloses an automatic material selection and conveying device for carton handle gaskets. This application automatically selects gaskets through a gasket selection mechanism, and the gasket transfer mechanism transfers the automatically selected gaskets to the gasket conveying mechanism, and then the gasket conveying mechanism conveys the gaskets to the rear end, which is used as the final installation position of the automatic installation device of the carton handle. The gasket travel switch is used to determine whether the gasket is in place, and the working process of each mechanism is controlled by the controller. Therefore, the original manual operation is completely changed to mechanical automation operation, which greatly improves the working efficiency, reduces labor costs, and has good economic benefits. In order to ensure that the entire device works stably and reliably, the gasket is always placed on the gasket slot of the gasket slat after being selected from the gasket selection mechanism. Therefore, the gasket will not move left and right significantly during the conveying process, and the gasket is always kept within the allowed range. The installation slot on the gasket always corresponds to the installation slot of the carton box body when the gasket is in the final installation position, so it has very good stability and accuracy. However, there are still the following problems in actual applications, specifically:

[0005] 1. When the existing bottom plate conveying device conveys the bottom plate through the handle, there is a certain distance between the bottom plate through the handle and the carton, which affects the subsequent assembly. At the same time, the device occupies a large space as a whole, the conveying efficiency is low, and it is impossible to ensure that the bottom plate through the handle is continuously loaded at equal distances during the conveying process;

[0006] 2. During the initial loading process of the bottom plate handle, it is necessary to manually put the stacked bottom plate handles into the silo, which affects the overall loading efficiency. At the same time, during the loading process, it is necessary to manually press the bottom film to ensure that the bottom film can be smoothly transported to the subsequent structure;

[0007] 3. During the conveying process of the plastic film, due to the reciprocating sliding of the push plate, under the influence of friction, the plastic film will slide slightly, affecting the stability of the plastic film conveying;

[0008] 4. The thickness of plastic films with different strength requirements is different. Therefore, in the process of limiting and conveying the plastic film, plastic films of different thicknesses are needed.

[0009] Therefore, the present invention provides an automatic feeding and conveying device for plastic bottom film for carton handles and a method thereof to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0052] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 11 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0053] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0054] The present invention discloses an automatic feeding and conveying device for plastic bottom film for carton handles and a method thereof, comprising a base 1, wherein the base 1 provides a fixed support foundation for subsequent structures, and the upper end of the base 1 is fixedly connected to two side plate frames 2 that are symmetrically distributed front and back, and the plastic bottom film is limited by the two side plate frames 2 to ensure that the plastic bottom film slides inside the side plate frames 2, and a supporting plate 3 is arranged between the two side plate frames 2, and the plastic bottom film is supported by the supporting plate 3 to avoid the problem of the plastic bottom film falling during the conveying process, and the supporting plate 3 is connected to the base 1. In this embodiment, the supporting plate 3 is fixedly connected to the base 1 to support the supporting plate 3, and a push plate 4 is slidably connected between the side plate frames 2 and the supporting plate 3, and the upper ends of the push plates 4 are fixedly connected with The wedge-shaped push block 5 and the wedge-shaped push blocks 5 on the two push plates 4 are symmetrically distributed front and back, and the two push plates 4 are symmetrically distributed on both sides of the supporting plate 3. The sliding of the push plate 4 and the wedge-shaped push block 5 drives the sliding of the plastic film on the supporting plate 3, thereby realizing the driving of the plastic film, and then realizing the conveying of the plastic film. The lower ends of the two push plates 4 are fixedly connected to the sliding frame 16 inside the base 1, and the sliding of the sliding frame 16 drives the push plates 4 to slide synchronously. The sliding frame 16 is connected to the driving device placed inside the base 1. The driving device described in this embodiment is an existing driving device, which realizes the reciprocating sliding of the push plate 4 left and right while reciprocatingly lifting and lowering, thereby realizing intermittent conveying of the plastic film, and reserving operation time for the installation of the plastic film.

[0055] The right end of the base 1 is fixedly connected to a loading rack 6, and a number of stacked plastic films are placed inside the loading rack 6. The loading of the side panel frame 2 is achieved through the loading rack 6, ensuring that the plastic films inside the side panel frame 2 are effectively distributed at equal intervals, and ensuring that there is enough plastic film inside the side panel frame 2. The base 1 is connected to a loading push plate 7 placed under the loading rack 6 for sliding left and right movement. The loading push plate 7 is located at the upper end of the supporting plate 3, and a loading push rack 8 is fixedly connected to the lower end of the loading push plate 7. The loading push rack 8 is connected to an external driving device. In this embodiment, the driving of the loading push rack 8 is achieved by an electric reciprocating push rod, so that the loading push plate 7 can slide back and forth inside the base 1, and then the plastic films at the bottom of the loading rack 6 are transported to the inside of the side panel frame 2 one by one.

[0056] The upper and lower sides of the loading rack 6 are rotatably connected to two rotating sprockets 9 symmetrically distributed up and down, a conveying chain 10 is connected between the two rotating sprockets 9, the conveying chain 10 is placed in the middle position of the loading rack 6 on the side close to the loading rack 6, and the conveying chain 10 is fixedly connected to a plurality of equally spaced limiting columns 11 on the side close to the loading rack 6, and the limiting columns 11 are driven to slide synchronously during the rotation of the conveying chain 10, a limiting box 12 is fixedly connected to the limiting column 11, and the limiting box 12 is driven to slide synchronously during the sliding process of the limiting column 11, and a pressing plate 13 is slidably connected inside the limiting box 12, and the pressing plate 13 is placed inside the loading rack 6, and the pressing plate 13 and the limiting box 12 The limit box 12 is connected by a spring, and the pressing plate 13 is driven to slide synchronously during the sliding process. The pressing plate 13 is inclined away from the limit box 12. The pressing plate 13 slides from top to bottom in the loading rack 6, thereby squeezing the plastic film entering the loading rack 6, ensuring that the plastic film continues to slide to the bottom of the loading rack 6, and at the same time squeezing the plastic film to ensure that the plastic film and the supporting plate 3 are effectively fitted. One of the rotating sprockets 9 is connected to an external driving device, and the rotating sprocket 9 is driven by the external driving device, thereby driving the conveying chain 10 to ensure effective conveying of the plastic film inside the loading rack 6.

[0057] The left end of the base 1 is fixedly connected to a support platform 14, and a hydraulic lifting platform 15 is slidably connected to the support platform 14 up and down. The hydraulic lifting platform 15 is connected to a hydraulic device connected to the base 1. The hydraulic device is a conventional pressure supply device and will not be described here. The hydraulic device is used to drive the hydraulic lifting platform 15 to rise and fall, thereby realizing the transportation of the plastic film transported to the hydraulic lifting platform 15 to the assembly position of the plastic film.

[0058] During the specific implementation of this embodiment, the plastic film is first placed inside the loading rack 6, and the driving sources of the rotating sprocket 9, the pushing rack 16 and the loading push rack 8 are started at the same time. The plastic film is continuously conveyed to the bottom of the loading rack 6 under the action of the conveying chain 10 and the pressing plate 13. At the same time, the loading push rack 8 conveys the plastic film at the lower end to the inside of the side plate rack 2 through the loading push plate 7 during the reciprocating sliding process. Then, the pushing rack 16 drives the plastic film to be intermittently conveyed to the other end of the base 1 during the reciprocating sliding process, and gradually conveys the plastic film to the left end of the base 1. The plastic film output from the side plate rack 2 falls onto the hydraulic lifting platform 15, and then the driving device of the hydraulic lifting platform 15 is started. Then, the plastic film is conveyed to the corresponding plastic film installation station, thereby realizing the effective conveying of the plastic film.

[0059] In order to ensure that the plastic film can be transported intermittently and at equal intervals, and at the same time avoid the problem that the reciprocating sliding process of the push plate 4 will cause the plastic film to retreat synchronously, the present embodiment provides a structure for effectively reciprocatingly slidingly driving the push plate 4. Specifically, the lower end of the loading push frame 8 is fixedly connected with two push ear plates, and the loading push frame 8 is driven to slide synchronously while the two push ear plates slide synchronously, thereby driving the push plate 4 to slide synchronously. The lower end of the push ear plate is rotatably connected with a rotating crank 17, and the other end of the rotating crank 17 is rotatably connected to a limited seat 18, and the limited seat 18 is connected to a limit rod 50 connected to the inside of the base 1. In this embodiment, the limit seat 18 and the limit rod 50 are fixedly connected, so that the rotating crank 17 rotates around the limit seat 18 while driving the push ear plate to slide, thereby realizing the driving of the loading push frame 8.

[0060] The limit rod 50 is slidably connected with a sliding seat 19, and the sliding seat 19 is threadedly connected to a reciprocating screw rod 20 rotatably connected to the inside of the base 1, and the reciprocating screw rod 20 is connected to a driving motor connected to the base 1 through a chain transmission mechanism. When the driving motor rotates, the reciprocating screw rod 20 is driven to rotate, and when the reciprocating screw rod 20 rotates, the sliding seat 19 is driven to slide back and forth. The sliding seat 19 is fixedly connected with a push rod 47 at one end close to the limit seat 18, and the push rod 47 is driven to slide synchronously during the sliding process of the sliding seat 19, and the push rod 47 is driven to rotate away from the end of the sliding seat 19. A primary crank 21 is rotatably connected, and the other end of the primary crank 21 is rotatably connected to a connecting crank 22. The connecting crank 22 and the rotating crank 17 are rotatably connected. During the sliding process of the push rod 47, the rotating crank 17 is driven by the connecting crank 22 and the primary crank 21, so that the push rod 47 reciprocates and drives the push ear plate to slide left and right while achieving up and down movement, thereby achieving intermittent transportation of the plastic film. The push plate 4 rises while sliding to the left and falls while sliding to the right, which can well realize the transportation of the plastic film and avoid the problem of the plastic film moving backward.

[0061] In the process of pressing the plastic bottom film by the pressing plate 13, when the plastic bottom film at the lower end is stacked too high, the pressing plate 13 may be blocked from sliding. At the same time, when the pressing plate 13 enters and exits the loading rack 6, there may be a problem that the pressing plate 13 and the loading rack 6 collide or even get stuck. Therefore, a method is provided to ensure that the pressing plate 13 slides smoothly. At the same time, during the continuous stacking process of the plastic bottom film, the pressing plate 13 cannot slide smoothly, resulting in equipment failure. Specifically, the pressing plate 13 is in a "V" shape at one end close to the loading rack 6, and the pressing plate 13 has a larger opening on the side close to the limit box 12, and a smaller opening on the side away from the limit box 12, so as to achieve effective pressing of the plastic bottom film. At the same time, when too many plastic films are stacked, the pressing plate 13 can be effectively stored in the limit box 12 to ensure the smooth sliding of the conveying chain 10. At the same time, the pressing plate 13 is in a "V" shape. The pressing plate 13 can be smoothly inserted between the two plastic films after stopping rotation, thereby avoiding hard extrusion with the plastic films, which causes the plastic films to deform. The front and rear sides of the pressing plate 13 are both arc-shaped. During the rotation process of the conveying chain 10, due to the synchronous sliding of the pressing plate 13, the pressing plate 13 will collide or get stuck. Therefore, the front and rear sides of the pressing plate 13 are arc-shaped to ensure that during the rotation process of the conveying chain 10, the pressing plate 13 can avoid faults.

[0062] After the conveying chain 10 is notified to rotate, in order to ensure the effective pressing of the plastic base film at the bottom of the loading rack 6 and to ensure that the loading push plate 7 can smoothly convey the plastic base film to the inside of the side plate rack 2, two symmetrically distributed pressing wedge plates 24 are arranged inside the lower side of the loading rack 6, and a sliding track 25 matching the pressing wedge plates 24 is provided on the loading rack 6. The pressing wedge plates 24 slide inside the sliding track 25, and the two pressing wedge plates 24 are fixedly connected with a sliding push plate 26 at one end away from the loading rack 6, and the sliding push plate 26 and the pressing wedge plates 24 slide synchronously.

[0063] The upper end of the base 1 is fixedly connected with a buffer box 27 placed on the right side of the loading rack 6, and an adjusting sleeve 28 is slidably connected to the inside of the buffer box 27 up and down. The adjusting sleeve 28 and the buffer box 27 are connected by a spring. Under the action of the spring, the adjusting sleeve 28 slides up and down, and the sliding push plate 26 is slidably connected to the inside of the adjusting sleeve 28 left and right. The sliding push plate 26 and the adjusting sleeve 28 are connected by a spring. When the sliding push plate 26 slides up and down, the adjusting sleeve 28 is driven to slide synchronously. At the same time, the sliding push plate 26 slides inside the adjusting sleeve 28. In the process of continuously conveying and pressing the plastic bottom film, the plastic bottom film squeezes the pressing wedge plate 24 to slide to the inside of the sliding track 25, thereby making the plastic bottom film slide downward smoothly. At the same time, when the conveying of the plastic bottom film is stopped, the pressing wedge plate 24 is reset to realize the pressing of the plastic bottom film at the lower end. At the same time, the adjusting sleeve 28 realizes effective pressing of the plastic bottom film at the lower end under the action of the spring.

[0064] In the process of conveying the plastic bottom film, due to the reciprocating sliding of the push plate 4, the plastic bottom film will slide slightly due to the contact friction force, which will lead to the problem that the subsequent conveying process of the plastic bottom film is unstable or even cannot be effectively conveyed. The side plate frame 2 is internally provided with a supporting bottom plate 29 fixedly connected to the supporting plate 3, and the plastic bottom film is further supported by the supporting bottom plate 29. The push plate 4 is located between the supporting bottom plate 29 and the supporting plate 3 to achieve effective support for the two ends and the middle part of the plastic bottom film. The side plate frame 2 is internally fixedly connected with the supporting bottom plate 29 located at the supporting plate 3. A limiting plate frame 30 is provided above the supporting bottom plate 29, and a plurality of limiting grooves 31 are provided on the limiting plate frame 30. A limiting fastening plate 32 which cooperates with the side plate frame 2 is slidably connected to the limiting plate frame 30 from top to bottom. A plurality of limiting arc blocks 33 which are equally spaced are fixedly connected to the lower end of the limiting fastening plate 32. The limiting arc blocks 33 cooperate with the limiting grooves 31. The limiting arc blocks 33 pass through the limiting grooves 31 and realize effective pressing of the plastic bottom film on the supporting bottom plate 29 to avoid shaking or slipping of the plastic bottom film due to contact friction. The limiting fastening plate 32 and the limiting plate are connected via a spring.

[0065] A strong electromagnetic suction cup 34 fixedly connected to the side panel frame 2 is arranged above the limit fastening plate 32, and an adsorption plate 35 matched with the strong electromagnetic suction cup 34 is fixedly connected to the upper end of the limit fastening plate 32. The strong electromagnetic suction cup 34 is connected to an external power supply, and the adsorption of the adsorption plate 35 is achieved by the discharge of the strong electromagnetic suction cup 34. With the cooperation of the strong electromagnetic suction cup 34 and the spring, the limit fastening plate 32 slides up and down inside the side panel frame 2. During the process of the limit fastening plate 32 sliding up and down, the plastic bottom film is pressed or released. When the plastic bottom film slides to the leftmost end, the limit fastening plate 32 slides downward to achieve the fastening and limiting of the plastic bottom film. At the same time, when the push plate 4 slides to the left, the limit fastening plate 32 slides upward to contact the limit of the plastic bottom film.

[0066] When conveying different plastic films, the thickness of plastic films with different bearing strengths will be different. In order to improve the universality of the equipment and be suitable for plastic films of different thicknesses, the present embodiment provides a structure for adjusting the distance between the support plate 3, the support bottom plate 29 and the limit plate frame 30. Specifically, a lifting support plate 48 is fixedly connected to the lower end of the support plate 3. The lifting support plate 48 and a hydraulic sleeve 49 fixedly connected to the inside of the base 1 are slidably connected up and down. The lifting support plate 48 and the hydraulic sleeve 49 are connected by a strong spring. The hydraulic sleeve 49 is connected to an external pressure supply device. The pressure supply device is used to supply pressure to the hydraulic sleeve 49, thereby adjusting the height of the support plate 3. When the position of the support plate 3 is raised or lowered, the support bottom plate 29 is driven to slide synchronously, thereby effectively clamping and limiting plastic films of different thicknesses.

[0067] In order to ensure the integrity of the equipment, ensure that the various parts can be effectively connected, and ensure that the plastic film can be intermittently conveyed while feeding into the loading rack 6, a support frame 36 is fixedly connected to the base 1, and a transfer shaft 37 is rotatably connected to the support frame 36. The transfer shaft 37 is connected to one of the rotating sprockets 9 through a chain transmission mechanism. A transfer sprocket 38 is coaxially connected to the other end of the transfer shaft 37. The transfer sprocket 38 and the reciprocating screw rod 20 are connected through a chain transmission mechanism, so that the reciprocating screw rod 20 is driven while the transfer shaft 37 is driven, thereby driving the rotating sprocket 9.

[0068] In the process of intermittently conveying the plastic film, in order to effectively control the feeding of the plastic film in the loading rack 6 and ensure uniform and synchronous feeding inside the loading rack 6, a limited track 39 is provided at the axis of the transfer sprocket 38, and a positioning groove 40 matching the limited track 39 is provided on the transfer shaft 37. A positioning arc block 41 is slidably connected inside the positioning groove 40, and the positioning arc block 41 and the positioning groove 40 are connected by a spring. An electromagnet 42 is fixedly connected inside the positioning groove 40, and the electromagnet 42 is connected to an external power supply. The positioning arc block 41 is made of magnetic adsorption material. The discharge of the electromagnet 42 realizes the adsorption control of the positioning arc block 41, and at the same time, the connection control of the transfer sprocket 38 and the transfer shaft 37 is realized through the lifting and lowering of the positioning arc block 41, so that the idling of the transfer shaft 37 or the rotation of the transfer shaft 37 drives the synchronous rotation of the transfer sprocket 38 to ensure that during the conveying process of the plastic film, the loading rack 6 stores enough plastic film, and the loading push rack 8 and the sliding seat 19 are fixedly connected to ensure that after the plastic film is conveyed to the assembly station, the plastic film at the lower end of the loading rack 6 can be conveyed to the inside of the side panel frame 2.

[0069] In order to achieve effective pressing of the limiting fastening plate 32 and ensure effective coordination during the pressing process and the plastic film conveying process, contact sensors 43 fixedly connected to the base 1 are arranged on the left and right sides of the sliding seat 19. The formation of the sliding seat 19 is monitored by the contact sensors 43. When the sliding seat 19 slides to the leftmost end, it contacts the contact sensor 43 on the left side. When the sliding seat 19 slides to the rightmost end, the sliding seat 19 contacts the contact sensor 43 on the right side. The strong electromagnetic suction cup 34 is effectively controlled by the contact sensor 43. When the sliding seat 19 contacts the contact sensor 43 on the left, the strong electromagnetic suction cup 34 is powered off, and the limiting fastening plate 32 slides downward, thereby achieving the clamping limit of the plastic film. When the sliding seat 19 contacts the contact sensor 43 on the right, the strong electromagnetic suction cup 34 is powered on, and the limiting fastening plate 32 slides upward, thereby achieving the release of the limit on the plastic film and ensuring the stability of the plastic film transportation.

[0070] A control module 44 is fixedly connected to the base 1, and the contact sensor 43, the strong electromagnetic suction cup 34, the electromagnet 42, and the drive motor are all connected to the control module 44. The contact sensor 43, the strong electromagnetic suction cup 34, the electromagnet 42, and the drive motor are controlled by the control module 44 to ensure the orderly operation of each part.

[0071] When the loading push plate 7 pushes the plastic bottom film to slide, the plastic bottom film at the bottom of the loading rack 6 will continue to fall. During the process of resetting the loading push plate 7, the plastic bottom film will be squeezed and even broken and wrinkled. Therefore, in order to overcome the above problem, the loading push plate 7 is fixedly connected with an extended push plate 45 on the side away from the push plate 4. The base 1 is provided with a storage rail 46 that cooperates with the extended push plate 45. The extended push plate 45 is used to support the subsequently falling plastic bottom film, ensuring that after the loading push plate 7 is reset, the plastic bottom film falls again to a state that cooperates with the loading push plate 7.

[0072] When the present invention is used, the plastic bottom film is first placed inside the loading rack 6, and the driving sources of the rotating sprocket 9, the push frame 16 and the loading push frame 8 are started at the same time. The plastic bottom film is continuously conveyed to the bottom of the loading rack 6 under the action of the conveying chain 10 and the pressing plate 13. At the same time, the pressing wedge plate 24 is used to realize continuous and effective extrusion of the plastic bottom film at the lower end, so that the subsequent loading push plate 7 can convey the plastic bottom film to the side plate frame 2. Then, the loading push frame 8 conveys the plastic bottom film at the lower end to the side plate frame 2 through the loading push plate 7 during the reciprocating sliding process. Inside, the push frame 16 then drives the plastic film to be intermittently transported to the other end of the base 1 during the reciprocating sliding process, and gradually transports the plastic film to the left end of the base 1, and outputs the plastic film of the side plate frame 2 to fall onto the hydraulic lifting platform 15, and then starts the driving device of the hydraulic lifting platform 15, and then transports the plastic film to the corresponding plastic film installation station to achieve effective transportation of the plastic film. After the transportation is completed, the sliding seat 19 is reset, and the limiting fastening plate 32 slides downward to achieve limiting clamping of the plastic film, and at the same time the push plate 4 is reset.

[0073] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
