Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, and more specifically, it relates to a pre - auxiliary device applied to the process of removing the lid of barreled water. Background Art

[0002] In the recycling barrel processing part of the barreled water production line, after the labels of the recycled five - gallon empty barrels are manually removed, they enter the production line for automatic lid removal and outer wall brushing of the empty barrels and other processing procedures. Among them, the stable operation and lid - removal effect of the lid - removal process directly affect the efficiency of the production line and even the quality of the finished products. Therefore, the lid - removal process is an important part of the recycled barrels and is the pre - condition of the whole production line.

[0003] The lids of barreled water are injection - molded from food - grade PE materials. In daily use, they are easily affected by the ambient temperature, becoming soft when heated and hard when cooled. Since they are used as barrel lids in barreled water production and must achieve the corresponding sealing effect, their matching degree requirements are even higher. Therefore, every slight change in them may affect the effect of the lid - removal process before production.

[0004] Currently, the commonly used automatic lid - remover has a lid - clamping head composed of two stainless - steel semi - circular clamping parts driven by a cylinder to complete the clamping action to hold the barrel lid and remove the lid. Due to the frequent opening and closing actions of the clamping head during production and the inability to achieve complete locking and reinforcement after clamping, the situation of the clamping head slipping and resulting in lid - removal failure often occurs in actual production, and its occurrence probability is about 3%. However, with the change of seasonal temperature, in the relatively cold winter, due to the influence of the low - temperature environment on the recycled empty barrels, the barrel lids harden when cooled, and the lid - removal failure rate instantly soars to more than 60%. Moreover, when the clamping head slips, plastic debris that damages the lid often falls into the barrel, causing a great potential safety hazard to product quality, resulting in the basic failure of automatic lid removal. Therefore, in order to ensure the normal production of barreled water and eliminate this great potential safety hazard to product quality, it is particularly important to upgrade and transform the lid - removal process. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a pre - auxiliary device applied to the process of removing the lid of barreled water, so that the empty barrels with the barrel lids heated and softened are transported into the subsequent automatic lid - remover, realizing easy lid removal and zero damage to the barrel lids.

[0018] The following combines the drawings and embodiments to describe the utility model in detail.

[0019] It should be noted that the orientation words such as "upper" and "lower" involved in this article are determined relative to the perspective of the drawings, and are only for the convenience of description and cannot be understood as a limitation to the technical solution.

[0020] As Figure 1 shown. The utility model proposes a pre - auxiliary device applied to the cap removal process of barreled water, which is arranged on the incoming barrel conveyor belt 9 and includes an in-line heater 1 and a steam generator 2. The in-line heater 1 is located above the incoming barrel conveyor belt 9. The in-line heater 1 is provided with a heating channel 3 along its own length direction for the barrel cover 11 of the barreled water to pass through. Two parallel steam distribution pipes 4 are arranged inside the in-line heater 1. The two steam distribution pipes 4 are respectively arranged on both sides outside the heating channel 3 along the length direction of the in-line heater 1. Both of the two steam distribution pipes 4 are connected to the steam generator 2. A plurality of steam nozzles 5 are arranged on both side surfaces of the heating channel 3 along the length direction of the in-line heater 1. The plurality of steam nozzles 5 on the same side are connected to the steam distribution pipe 4 on the same side.

[0021] Figure 1 The shown angle is a schematic diagram showing the cross - section direction of the heating channel 3. In Figure 1 the perspective, the transportation direction of the empty barrel 10 is perpendicular to the paper surface outward or perpendicular to the paper surface inward.

[0022] In the present utility model, the pre - auxiliary device is located before the cap - removing process. Along the transportation path of the empty barrel 10, the empty barrel 10 first passes through the pre - auxiliary device, and the barrel cap 11 enters the heating channel 3. It is easy to understand that the direction of the heating channel 3 is the same as the direction of the incoming - barrel conveyor belt 9 below. The barrel cap 11 is entirely within the heating channel 3. The barrel cap 11 of the empty barrel 10 stays in the online heater 1 for 15 - 20 seconds to ensure the heating and softening effect of the online heater 1 on the barrel cap 11, so as to achieve the best cap - removing effect for the subsequent automatic cap - removing process.

[0023] In the present utility model, the steam generator 2 is a conventional existing device, such as a steam generator 2 with a power of 9KW.

[0024] Preferably, within the heating channel 3, the heights of all the steam nozzles 5 are the same, and when the barrel cap 11 is within the heating channel 3, the steam nozzles 5 are aligned with the middle position of the barrel cap 11 to achieve the best heating effect.

[0025] Preferably, the length of the online heater 1 is 700 - 800mm, the outer width is 200 - 300mm, the length of the steam distribution pipe 4 is 600 - 650mm, and the length of the steam distribution pipe 4 is less than the length of the online heater 1. More preferably, the length of the online heater 1 is 730mm, the outer width is 200mm, and the length of the steam distribution pipe 4 is 650mm. It is easy to understand that generally 2 - 3 empty barrels 10 are accommodated within the online heater 1.

[0026] Preferably, the pre - auxiliary equipment further includes a detection photoelectric eye. The detection photoelectric eye is arranged on the side of the incoming - barrel conveyor belt 9 and outside the barrel - discharging end of the online heater 1 to detect the empty barrel 10 leaving the online heater 1. Taking two empty barrels 10 that are closely adjacent front - to - back entering and leaving the online heater 1 as an example, when the detection photoelectric eye detects that an empty barrel 10 has left the online heater 1, the incoming - barrel conveyor belt 9 below the online heater 1 stops. The other empty barrel 10 is then at the barrel - discharging end of the online heater 1 and stays for a period of time so that the total time for this empty barrel 10 to stop and move within the online heater 1 is 15 - 20 seconds, and then this empty barrel 10 leaves the online heater 1, thereby realizing the control. It is easy to understand that when the online heater 1 is filled with the barrel caps 11 of the empty barrels 10, every time a new empty barrel 10 enters, an empty barrel 10 will leave the online heater 1.

[0027] Preferably, the front-end auxiliary device further includes a barrel blocking assembly, which includes a barrel blocking cylinder and a barrel blocking member. The barrel blocking cylinder is arranged on the side of the barrel feeding conveyor belt 9 and outside the barrel discharging end of the on-line heater 1. The barrel blocking member is connected to the piston member of the barrel blocking cylinder. The barrel blocking member extends out to block the empty barrel 10. It is easy to understand that the function of the barrel blocking assembly is to prevent the empty barrel 10 in the on-line heater 1 from moving forward due to inertia and leaving the on-line heater 1 or tipping over when the barrel feeding conveyor belt 9 stops.

[0028] In the present utility model, the steam generator 2, the barrel blocking cylinder, the detection electric eye, etc. are all connected to the electrical control device. The electrical control device is a conventional existing control device. For example, it was originally the control device of a barreled water recycling system, and the present utility model does not make any restrictions.

[0029] Preferably, the front-end auxiliary device further includes a barrel body support assembly, which includes a support rod 6 and a cross bar 7. The two support rods 6 are located below the on-line heating assembly and arranged on both sides of the barrel feeding conveyor belt 9. The top of the support rod 6 is provided with a cross bar 7, and the assembly between the two cross bars 7 is larger than the outer diameter of the barrel body of the empty barrel 10. The functions of the support rod 6 and the cross bar 7 are to prevent the empty barrel 10 from tipping over due to inertia during the conversion of the moving and stopping states. The length of the cross bar 7 is greater than or equal to the length of the on-line heater 1.

[0030] More preferably, the barrel body support assembly further includes a rotary cylinder 8. The cylinder body of the rotary cylinder 8 is arranged outside the barrel feeding conveyor belt 9. The bottom end of the support rod 6 is connected to the rotating member of the rotary cylinder 8, and the support rod 6 is controlled to rotate by the rotary cylinder 8. When the empty barrel 10 is in the moving process, the rotary cylinder 8 controls the support rod 6 to rotate in a direction away from the empty barrel 10. When the empty barrel 10 is in a stationary state, the rotary cylinder 8 controls the support rod 6 to rotate in a direction towards the empty barrel 10, so that the cross bar 7 at the top of the support rod 6 is as close as possible to the empty barrel 10.

[0031] In actual production, the operator continuously places the empty barrel 10 with the label removed on the barrel feeding conveyor belt 9, so that each empty barrel 10 passes through the on-line heater 1 and stays for heating. The empty barrel 10 with the heated and softened barrel cover 11 is conveyed into the subsequent automatic cap remover. When the automatic cap remover removes the cap from the heated and softened barrel cover 11, it can achieve easy cap removal, cause zero damage to the barrel cover 11, and directly reduce the cap removal failure rate to zero. This greatly improves the stability of the production line operation and production efficiency, and at the same time can eliminate the potential safety hazards that the cap removal process may affect the product quality.

[0032] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
