Description

Technical Field

[0001] The present application relates to the field of discharging devices, and in particular to a discharging structure of a heat sealing device. Background Art

[0002] At present, the heat sealer for plastic films is a sealing machine. It is suitable for sealing and bagging plastic films. It is an ideal sealing equipment for food factories, cosmetic factories, pharmaceutical factories and other units. After the heat sealing of the material is completed, it is transmitted to the outside by the heat sealing mechanism and unloaded through the external discharge structure to prevent the material from being damaged. The existing discharge structure usually achieves a rebound buffering effect by loading a spring on the plate surface supporting the material.

[0003] For example, patent number CN202123300190.3, a buffer discharge device for a heat sealing machine of plastic packaging film, includes a bottom plate, a telescopic rod is fixedly installed on the top of the bottom plate, a spring No. 1 is movably sleeved on the side end of the telescopic rod, a placement plate is fixedly installed on the top of the telescopic rod, a flat plate is fixedly installed on one side of the placement plate, a shock-absorbing pad is fixedly installed on the top of the placement plate, the number of the telescopic rods is two, the number of the telescopic rods is two, the telescopic rods are symmetrically arranged, support rods are fixedly installed on both sides of the bottom end of the placement plate, the bottom end of the support rod is movably sleeved with a sleeve, and the bottom end of the sleeve is fixedly connected to the bottom plate. The above device has the following deficiencies in actual use:

[0004] The device uses two springs set on the surface of the bottom plate as the main source of buffering efficiency. As the amount of material stacked on the placement plate increases, its buffering efficiency and stability gradually decrease, and the material is still easily broken in the end. At the same time, manual labor is required to regularly push the placement plate full of materials for unloading, which reduces efficiency and increases labor costs. Utility Model Content

[0005] In order to improve the problem that the conventional discharging structure has poor buffering performance for materials, thereby resulting in low discharging efficiency and high labor costs, the present application provides a discharging structure for a heat sealing device.

[0006] The discharging structure of a heat sealing device provided in the present application adopts the following technical solution:

[0007] A material discharging structure of a heat sealing device comprises a main frame, a mounting groove is provided on one side of the main frame, and a guide mechanism is provided on the surface of the mounting groove;

[0008] The guide mechanism comprises a rotating seat movably arranged at the notch of the installation slot, and a support shell is rotatably arranged at one end of the rotating seat away from the main frame, and a movable slot is opened on the upper end surface of the support shell, and elastic blocks are fixed on both sides of the movable slot;

[0009] The buffer mechanism comprises a movable seat fixed on the top of the elastic block, a buffer groove is provided on the top of the movable seat, a support rod is movably arranged in the buffer groove, and a pressure plate is fixed on the top of the support rod.

[0010] By adopting the above technical solution, when the heat-sealed material falls onto the surface of the pressure plate, the pressure plate is pressed downward into the buffer groove for initial force unloading. While the pressure plate is pressed in, pressure is simultaneously applied to the supporting movable seat, so that the movable seat is pressed into the movable groove to squeeze the elastic block, thereby achieving a secondary force unloading effect, thereby reducing the damage caused by the falling of the material.

[0011] Preferably, a reciprocating screw is rotatably arranged in the installation groove, and one end of the rotating seat close to the main frame is threadedly connected to the surface of the reciprocating screw.

[0015] Preferably, the guide mechanism also includes a rotating rod fixedly mounted on one end of the rotating seat away from the main frame, a rotating plate is fixedly mounted on the side of the support shell close to the rotating seat, the rotating plate is rotatably connected to the surface of the rotating rod, and limit blocks are fixedly mounted on both sides of the support shell adjacent to the rotating plate.

[0016] By adopting the above technical solution, the support shell is rotatably connected to the rotating seat through the rotating plate, so that the support shell rotates around the rotating rod, thereby tilting to achieve the effect of unloading.

[0017] Preferably, the buffer mechanism further comprises a connecting ring threadedly connected to the buffer groove, and the internal thread of the connecting ring is connected to the surface of the support rod.

[0018] By adopting the above technical solution, the inner and outer surfaces of the connecting ring are respectively connected to the support rod and the buffer groove. When the support rod is pressed into the buffer groove, the connecting ring thread rotates to unload the force, thereby achieving a buffering effect.

[0019] Preferably, a snap-in groove is provided in the middle of the lower end surface of the pressure plate, the middle of the bottom of the snap-in groove is fixedly connected to the top of the support rod, springs are fixedly provided on both sides of the lower end surface of the pressure plate, and one end of the spring away from the pressure plate is fixedly connected to the upper end surface of the movable seat.

[0020] By adopting the above technical solution, the part of the surface of the snap-in groove except the support rod is snap-fitted with the protrusion of the buffer groove, thereby limiting and fixing. At the same time, the support rod keeps the pressure plate fixedly connected to the movable seat.

[0021] Preferably, upper guide blocks are fixedly provided at both ends of the side surface of the main frame close to the supporting shell, and two lower guide blocks are fixedly provided at the bottom of the two upper guide blocks on the side surface of the main frame.

[0022] By adopting the above technical solution, when the pressure plate moves to be aligned with the conveying mechanism, the upper guide block abuts against the limit block to perform a clamping limit, so that the pressure plate remains horizontal; when the pressure plate moves to the bottom of the main frame, the lower guide block abuts against the limit block to perform a clamping limit, so that the pressure plate tilts, thereby allowing the material to slide into the storage mechanism on one side.

[0024] By adopting the above technical solution, the conveying mechanism transmits the heat-sealed material, and the partition curtain slows down the speed at which the material falls when it is transmitted from the conveying mechanism, thereby preventing the material from sliding out of the range of the pressure plate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Use the support rod to apply pressure to the connecting ring, so that the connecting ring rotates into the buffer groove to generate mutual force to rotate the support rod into the buffer groove, thereby initially unloading the pressure generated by the material on the pressure plate. In addition, the movable seat is pressed into the movable groove and rebounded by the elastic block, which secondarily unloads the pressure of the material, thereby effectively buffering the pressure generated by the material;

[0027] 2. The reciprocating screw drives the support shell to move, so that the limit block is pressed against the lower guide block, thereby causing the support shell to tilt and the material on the surface of the pressure plate to slide into the collection mechanism. The process is automatic and does not require human intervention, thereby reducing labor costs and improving discharge efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses a material discharging structure of a heat sealing device.

[0039] Example 1

[0040] Reference Figure 1 , 2 A discharging structure of a heat sealing device comprises a main frame 1, a groove is provided in the middle of the main frame 1, and a conveying mechanism 2 is installed on both sides of the groove channel, a partition curtain 11 is fixedly provided at the top of the groove on one side of the groove of the main frame 1, and the bottom of the partition curtain 11 blocks the roller on one side of the conveying mechanism 2, a mounting groove 3 is longitudinally provided at the bottom of the main frame 1 located at the bottom of the conveying mechanism 2, and the upper and lower end surfaces of the channel of the mounting groove 3 are rotatably connected to the upper and lower ends of a reciprocating screw 7, a bottom groove 6 is provided at the bottom of the main frame 1 located at the bottom of the mounting groove 3, a servo motor 8 is fixedly provided on the bottom surface of the bottom groove 6 by screws, and the output shaft of the servo motor 8 movably passes through the side wall and is fixedly connected to the bottom end of the reciprocating screw 7.

[0041] It should be noted that a heat sealing mechanism for heating is provided on the top of the main frame 1 to perform heat sealing treatment on the materials entering the main frame 1, and a collecting mechanism is provided on one side of the main frame 1 to collect the materials. Since the heat sealing mechanism and the collecting mechanism are existing conventional devices, their structural principles will not be described in detail.

[0042] Through the above arrangement, when the material is transported to the inside of the groove of the main frame 1 through the conveying mechanism 2, it is heated and sealed by the heat sealing mechanism, and then the conveying mechanism 2 transports the heated material out of the main frame 1. During the material transportation process, it abuts against the partition curtain 11 to generate friction, thereby slowing down the material movement speed and preventing the material from being transported too quickly and leaving the range of the buffer mechanism 5. At the same time, the servo motor 8 drives the reciprocating screw 7 to rotate, thereby providing power for the subsequent operation of the guide mechanism 4.

[0043] Reference Figure 2 , 3 The guide mechanism 4 includes a rotating seat 46 threadedly connected to the surface of the reciprocating screw 7, and a through hole is provided on the surface of the rotating seat 46. The thread in the through hole is consistent with the thread torque on the surface of the reciprocating screw 7. The rotating seat 46 is provided with a groove at the other end relative to the reciprocating screw 7, and a rotating rod 47 is fixed in the groove. The surface of the rotating rod 47 is smooth, and a rotating plate 45 is rotatably connected to the smooth surface. A support shell 41 is welded and fixed to the end of the rotating plate 45 away from the rotating rod 47. Rectangular limit blocks 44 are fixed on both sides of the outer surface of the support shell 41 adjacent to the rotating plate 45. An elliptical movable groove 42 is provided on the upper end surface of the support shell 41. Elastic blocks 43 are fixed on both sides of the bottom of the movable groove 42. The elastic block 43 is made of rubber material, and a layer of elastomeric adhesive is provided on the outer surface of the elastic block 43.

[0044] It should be noted that a layer of viscosity damping material is provided between the rotating plate 45 and the rotating rod 47 to increase the friction between the rotating plate 45 and the rotating rod 47 , so that the rotating plate 45 has a certain rotation ability and also has fixity.

[0045] Through the above arrangement, when the reciprocating screw 7 rotates, the rotating seat 46 moves up and down back and forth along the surface of the reciprocating screw 7. When the rotating seat 46 moves, it drives the rotating plate 45 to move, thereby causing the support shell 41 to move up and down back and forth along the reciprocating screw 7. At the same time, the elastic block 43 provides resilience to the subsequent guide mechanism 4, thereby helping to increase the buffering effect.

[0046] Reference Figure 3 , 5The buffer mechanism 5 includes a movable seat 55 bonded and fixed to the upper end surfaces of the two elastic blocks 43. The movable seat 55 is T-shaped as a whole and has a protrusion at the bottom. The protrusion at the bottom of the movable seat 55 is clamped between the two elastic blocks 43. A buffer groove 56 is provided in the middle of the upper end surface of the movable seat 55. The groove surface of the buffer groove 56 is surrounded by a thread. A connecting ring 54 is provided with an inner thread of the buffer groove 56. A thread is fixed on the outer surface of the connecting ring 54. The outer thread of the connecting ring 54 is consistent with the inner thread of the buffer groove 56 in torque and keeps abutting. The inner surface of the connecting ring 54 is provided with an inner thread. The inner surface of the connecting ring 54 is provided with a support rod 53. The thread on the surface of the support rod 53 is consistent with the inner thread of the connecting ring 54 in torque and keeps abutting.

[0047] It should be noted that, under normal conditions, the upper end surface of the movable seat 55 is flush with the upper end surface of the support shell 41 , and the surface diameter of the buffer groove 56 through hole is smaller than the diameter inside the through hole, so that the connecting ring 54 is longitudinally fixed in the channel of the buffer groove 56 .

[0048] Through the above arrangement, when the support rod 53 is pressed downward by pressure, the external thread of the support rod 53 drives the connecting ring 54 to rotate, and the connecting ring 54 rotates in the buffer groove 56 through the connection of the external thread, so that the support rod 53 is transferred into the buffer groove 56, thereby reducing the pressure and performing buffering.

[0049] Reference Figure 4 , 5 A pressure plate 51 is fixed on the top of the support rod 53, and a clamping groove 52 is opened at the center of the bottom of the pressure plate 51. The top of the support rod 53 is fixed to the center of the bottom of the clamping groove 52. Springs 57 are welded and fixed on both sides of the upper end surface of the movable seat 55, and the other ends of the two springs 57 away from the movable seat 55 are respectively fixed to the relative positions of the bottom surface of the pressure plate 51 to form an overall fixation.

[0050] It should be noted that, under normal conditions, the upper end surface of the pressure plate 51 is flush with the roller surface of the conveying mechanism 2, so as to facilitate receiving the conveyed material. A layer of rubber is provided on the surface of the pressure plate 51, so as to increase the friction between the material and the pressure plate 51 and have a certain buffering effect.

[0051] Through the above arrangement, when the surface of the pressure plate 51 supports the material, it is pressed downward by the pressure exerted by the material, and the pressure is transmitted to the support rod 53. When the support rod 53 is rotated into the buffer groove 56, the groove surface of the snap-in groove 52 is snap-fitted with the protrusion outside the buffer groove 56, which plays an auxiliary fixing effect. At the same time, two springs 57 connect the pressure plate 51 and the movable seat 55, providing an auxiliary rebound effect for the pressure plate 51.

[0052] Reference Figure 1The two ends of the side of the main frame 1 close to the supporting shell 41 are fixed with lower guide blocks 9, and the side of the main frame 1 is fixed with two upper guide blocks 10 on the top of the two lower guide blocks 9. The bottom surface of the upper guide block 10 is provided with a slot, and the slot is plugged with the limit block 44.

[0053] Through the above arrangement, when the support shell 41 moves downward, one end of the limit block 44 abuts against the lower guide block 9. The lower guide block 9 is in a fixed state, thereby applying a thrust to the limit block 44. The limit block 44 is subjected to the thrust and transmitted to the support shell 41, so that the support shell 41 and the pressure plate 51 are tilted as a whole, and the material on the surface of the pressure plate 51 is dumped into the collection mechanism on one side. When the support shell 41 moves upward, the limit block 44 abuts against the upper guide block 10, so that the support shell 41 and the pressure plate 51 remain horizontal as a whole, which is convenient for receiving the next material.

[0054] The transmission mechanism 2, reciprocating screw 7 and servo motor 8 mentioned in the device are all prior art, and their structural principles are not described in detail. The servo motor 8 is set to be a Guangzhou Demark 60 DC low-voltage servo motor, and the servo motor 8 is also adapted with a compiler and a microcomputer to control the operation of the servo motor 8.

[0055] The implementation principle of the discharging structure of a heat sealing device in the embodiment of the present application is:

[0056] When using the device, the material is transported to the inside of the main frame 1 through the conveying mechanism 2, and the heat sealing mechanism inside the main frame 1 performs heat sealing on the material, and then the conveying mechanism 2 conveys the heat-sealed material to the surface of the pressure plate 51;

[0057] When the material falls onto the surface of the pressure plate 51, the pressure plate 51 is pressed downward, and the support rod 53 is pressed to apply pressure to the downward connecting ring 54. The connecting ring 54 is pressed to rotate along the inclined thread of the buffer groove 56. When the connecting ring 54 rotates, it drives the support rod 53 to rotate downward synchronously, so that the pressure plate 51 moves downward, preliminarily reducing the impact of the falling material.

[0058] When the pressure plate 51 is pressed down, pressure is applied to the movable seat 55, and the movable seat 55 is pressed downward to apply pressure to the two elastic blocks 43. The elastic blocks 43 are squeezed into the cavity in the middle of the movable groove 42 under the pressure and then rebound to release the pressure, thereby secondarily alleviating the impact of the material falling and protecting the material.

[0059] After the conveying mechanism 2 conveys the material to the upper end of the pressure plate 51, the conveying mechanism 2 pauses for a certain period of time. The pause time needs to be set according to actual needs. During the pause of the conveying mechanism 2, the microcomputer sends a signal to start the servo motor 8. The servo motor drives the reciprocating screw 7 to rotate, and controls the rotating seat 46 to move downward along the surface of the reciprocating screw 7. The rotating seat 46 drives a series of structures such as the support shell 41, the movable seat 55 and the pressure plate 51 to descend. As the support shell 41 descends, the limit block 44 abuts against the lower guide block 9 to generate an offset, so that the support shell 41 rotates around the rotating rod 47. At this time, the pressure plate 51 on the top of the support shell 41 rotates synchronously to form an inclination, so that the material on the surface of the pressure plate 51 slides into a collecting mechanism set on one side.

[0060] When the material collection is completed, the rotating seat 46 is rotated by the reciprocating screw 7 and cyclically rises, thereby causing the support shell 41 to rise. As the support shell 41 rises, the limit block 44 abuts against the upper guide block 10, thereby causing an offset again. Finally, the limit block 44 is engaged with the slot of the upper guide block 10 to form a horizontal state, so that the support shell 41 returns to a parallel state as a whole. At this time, the pause of the conveying mechanism 2 ends, and the next material continues to be conveyed to the surface of the pressure plate 51.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
