Description

Technical Field

[0001] The utility model relates to the technical field of material packaging, in particular to a packaging machine unloading mechanism capable of adjusting the unloading amount. Background Art

[0002] A packaging machine is a machine that can complete all or part of the packaging process of products and commodities. The packaging process includes the main processes such as unloading, wrapping, sealing, and related processes before and after. At present, the functions of packaging machines have been improved, and packaging efficiency has become a major direction for packaging machine improvement.

[0003] There are many types of packaging machines. At present, most packaging machines can realize automatic unloading, automatic bag pulling and sealing and other multi-step synchronous operations (i.e. automatic packaging machines), which can greatly improve the efficiency of packaging. Moreover, the quality of each bag is not much different during packaging, which can ensure the quality of packaging.

[0004] As mentioned above, the existing automatic packaging machines usually put the materials into a turntable when unloading, and at the same time open multiple drop holes on the bottom circumference of the turntable. When the turntable is rotating, any drop hole can correspond to the drop tube at the bottom to realize the unloading, so that the material can directly fall into the packaging bag that has been pulled open below, realizing automatic unloading and packaging.

[0005] However, according to the existing demand, when some small factories produce multiple products, if they use the same packaging machine for packaging, the size of the blanking hole in the turntable and the blanking barrel below are fixed during the blanking process, which makes it difficult to adjust the blanking amount, and it is not convenient to package different materials or different packaging bags of the same material. Utility Model Content

[0006] Therefore, in order to solve the above-mentioned deficiencies, the utility model provides a packaging machine feeding mechanism with adjustable feeding amount. The feeding mechanism can be directly used in the existing automatic packaging machine. By setting a rotating feeding barrel and several feeding holes distributed circumferentially in the feeding barrel, automatic feeding operation is convenient. At the same time, a slidable feeding baffle is arranged under the feeding barrel, and several feeding barrels of different sizes are arranged on the feeding baffle, so that any feeding barrel can be matched with the feeding hole to realize automatic falling of the material, and the feeding baffle can be slid according to different feeding amounts, so as to facilitate the matching of feeding barrels of corresponding sizes with the feeding holes. Finally, a fixing mechanism for fixing the feeding barrel is arranged under the feeding barrel, which effectively prevents the feeding baffle from moving randomly during the packaging process and affects the feeding, thereby ensuring normal feeding.

[0011] Specifically, there is a gap between the inner bottom of the support tube and the baffle, and a sliding hole is opened at the bottom of the support tube corresponding to the connecting hole of the baffle. The blanking baffle is slidably clamped in the sliding hole and keeps the top support of the blanking baffle sliding in the gap between the inner bottom of the support tube and the baffle.

[0012] Specifically, the bottom of the support tube is fixed to the support body through a support rod, and a fixing mechanism that can slide up and down along the support rod is provided at the outer end of any one of the support rods.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further specifically described below through specific embodiments in combination with the accompanying drawings; it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention in any way; the accompanying drawings in the present invention are only used to assist in the description of the embodiments and to facilitate understanding, and are not intended to limit the present invention in any way.

[0033] As described in the background art, the existing automatic packaging machine cannot adapt to the feeding operation of different materials or different packaging bag sizes of the same material because the feeding amount is not easy to adjust during the feeding process, and is not very practical.

[0034] For the reasons stated above, please refer to the attached Figure 1 The utility model provides a packaging machine feeding mechanism with adjustable feeding amount, comprising a feeding barrel 7, which is rotatably arranged on a support body 1 and has a plurality of feeding holes distributed along the circumference at the inner bottom of the feeding barrel 7;

[0035] The support cylinder 5 is sleeved on the outside of the lower cylinder 7 and fixed on the support body 1;

[0036] A baffle 16 is arranged in the gap between the bottom of the support tube 5 and the bottom of the discharge tube 7. A connecting hole corresponding to any one of the discharge holes of the discharge tube 7 is opened on the baffle 16. A discharge baffle 17 is slidably arranged at the bottom of the support tube 5. A plurality of discharge tubes 12 of different sizes are arranged on the discharge baffle 17. Each of the discharge tubes 12 can correspond to and communicate with the connecting hole of the baffle 16. A lifting and lowering fixing mechanism is also arranged at the lower end of the support tube 5. The fixing mechanism is used to connect and fix any one of the discharge tubes 12 with the connecting hole of the baffle 16.

[0037] According to the technical features described in the previous paragraph, a baffle is set between the support cylinder and the discharge cylinder to prevent the material in the discharge hole in the discharge cylinder from falling directly into each discharge cylinder below, causing the material to fall randomly. A connecting hole opened on the baffle can correspond to any discharge cylinder below and the external bag pulling mechanism to perform discharge operations.

[0038] Please see attached Figure 1 and attached Figure 2 Specifically, a driving device 2, a transmission rod 3 and a transmission mechanism 4 are provided in the support body 1. The top end of the transmission rod 3 passes through the support body 1. The discharge barrel 7 is arranged on the transmission rod 3 above the support body 1 and keeps the same axis.

[0039] Furthermore, the driving device can be configured as a three-phase asynchronous motor, and the transmission mechanism can be configured as a gear transmission mechanism (as shown in the accompanying drawings), or can be replaced by a grooved wheel transmission mechanism that facilitates intermittent motion.

[0040] Please attach Figure 7 ~Attached Fig. 9 It can be seen that, specifically, there is a gap between the inner bottom of the support tube 5 and the baffle 16, and a sliding hole is opened at a position corresponding to the bottom of the support tube 5 and the connecting hole of the baffle 16, and the blanking baffle 17 is slidably clamped in the sliding hole and keeps the top support of the blanking baffle 17 to slide in the gap between the inner bottom of the support tube 5 and the baffle 16.

[0041] For further information, please refer to the attached Figure 7 The sliding hole is a semicircular slot-shaped hole, the center of which is located on the central axis of rotation of the discharge barrel, and the blanking baffle is an arc-shaped plate of 1 / 4 circle, which can be clamped in the slot-shaped hole for sliding.

[0042] Furthermore, several through holes are opened in the circumferential direction on the arc plate of the blanking baffle, each through hole corresponds to the blanking barrel, the outer diameter of each blanking barrel remains the same, and the inner diameter increases or decreases sequentially, which is convenient for the staff to adjust.

[0043] Specifically, the bottom of the support tube 5 is fixed to the support body 1 through a support rod 6, and a fixing mechanism that can slide up and down along the support rod 6 is provided at the outer end of any one of the support rods 6. An adjusting rod 15 is also provided between the bottom of the support tube 5 and the support body 1, and the adjusting rod 15 is used to realize the up and down sliding and fixing of the fixing mechanism.

[0044] Specifically, the fixing mechanism includes a fixing plate 14 and a fixing cylinder 13. One end of the fixing plate 14 is respectively sleeved on the outer ends of the adjusting rod 15 and the supporting rod 6 to slide up and down. The fixing cylinder 13 is conical and keeps the large end portion sleeved on the outer end of any one of the blanking cylinders 12. The outer end of the adjusting rod 15 is provided with an external thread and a fastener (i.e., a nut) screwed with the external thread is provided on the outside. The fastener maintains contact with the fixing plate 14.

[0045] According to the technical features described in the previous paragraph, the fixed plate that slides up and down and the conical fixed cylinder are provided to facilitate the separation of the fixed cylinder and the blanking cylinder when moving downward, thereby facilitating the sliding of the blanking baffle. When moving upward, the fixed cylinder presses the blanking cylinder tightly to fix the blanking baffle. The fixed plate can be fixed to the support rod by providing fasteners and maintaining an adjusting rod with a threaded connection.

[0046] Specifically, a mounting plate 8 is provided at a position corresponding to the connecting hole on the outer side of the top end of the support cylinder 5 , and a pushing mechanism for pushing the material in any blanking hole in the blanking cylinder 7 into the blanking cylinder 12 is provided on the mounting plate 8 .

[0047] Specifically, the pushing mechanism includes a linear telescopic device 9, which is arranged at the outer end of the support tube 5 and fixed to the bottom of the mounting plate 8 and keeps the telescopic end extending upward through the mounting plate 8;

[0048] A movable plate 10, one end of which is fixed to the telescopic end of the linear telescopic device 9;

[0049] One end of the push rod 11 is fixed to the other end of the movable plate 10 , and the other end passes through the mounting plate 8 and corresponds to the position of the connecting hole of the baffle 16 .

[0050] According to the technical features described in the previous paragraph, the pushing mechanism is provided to facilitate the rapid pushing of the material in the blanking hole into the blanking tube and the external bag pulling mechanism, so as to achieve rapid material discharge and improve packaging efficiency.

[0051] During the adjustment process of the blanking mechanism, the fastener is first rotated to drive the fixed plate 14 to move downward until the fixed cylinder 13 on the fixed plate 14 is separated from the blanking cylinder 12, and then the appropriate blanking cylinder 12 (if the blanking amount is larger, the inner diameter of the blanking cylinder 12 is larger, and vice versa) is moved to the connecting hole position of the baffle 16 according to the required blanking amount, and then the fastener is reversed to drive the fixed plate 14 to move upward, and finally the fixed cylinder 13 is sleeved on the outside of the blanking cylinder 12 to tighten it (because the fixed cylinder 13 is conical and the large end is facing upward, it can be fixed) to achieve fixation and complete the adjustment.

[0052] During the unloading process, the driving device 2 moves once, driving the unloading barrel 7 to rotate one station, that is, the unloading hole corresponds to the connecting hole of the baffle 16, and the material in the unloading hole loses the obstruction of the baffle 16 and enters the unloading barrel 12 below from the connecting hole. Under the action of gravity and the push of the pushing mechanism, it enters the bag pulling mechanism at the outer end to realize unloading and packaging.

[0053] The above description is a detailed description of the preferred feasible embodiment of the utility model, but the embodiment is not used to limit the scope of the patent application of the utility model. All equivalent changes or modified changes completed under the technical spirit suggested by the utility model should fall within the patent scope covered by the utility model.
