Description

Technical Field

[0001] The utility model relates to the technical field of material packaging, in particular to a packaging machine unloading device equipped with a material blocking mechanism. 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] At present, most packaging machines use packaging machinery for automated mechanized packaging, which can effectively reduce the complicated steps of manual packaging. The packaged products have good quality and high efficiency, and are suitable for large-scale production.

[0004] In the packaging process, unloading is an important step. Existing automatic packaging machines can realize quantitative unloading. The unloading principle is mostly to put the material into a rotating disk, and at the same time, evenly open unloading holes on the edge of the rotating disk. When the unloading holes of the rotating disk correspond to the external unloading barrel during the rotation of the rotating disk, the internal material can fall under the action of gravity, realizing the automatic unloading process.

[0005] However, it is difficult to automatically discharge some lighter materials (such as dried chili segments) during the feeding process. Therefore, in order to increase the feeding speed, some auxiliary equipment (such as pushing mechanism, blowing mechanism, etc.) is added to push the material or blow it downward to achieve feeding. However, when feeding through the blowing mechanism, it is easy to cause the material to fly out, resulting in material splashing everywhere, causing waste and affecting the processing environment.

DETAILED DESCRIPTION

[0033] 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.

Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0035] As described in the background technology, when unloading lighter materials, the existing packaging machine unloading device often adopts some auxiliary equipment (such as a pushing mechanism or a blowing mechanism) to assist in unloading the materials in order to increase the unloading speed of the materials. However, in the process of using the auxiliary blowing mechanism to blow the materials, it is easy to cause the materials to splash all over the outside, thereby causing waste of materials.

[0036] Based on the above reasons, the utility model provides a packaging machine unloading device equipped with a material blocking mechanism, comprising a unloading barrel 7, which is rotatably arranged on a support body 1 and has a plurality of unloading holes distributed along the circumference at the inner bottom of the unloading barrel 7;

[0037] The support cylinder 5 is sleeved on the outside of the lower cylinder 7 and fixed on the support body 1;

[0038] A material dropping mechanism is arranged on the support cylinder 5, and a pushing mechanism for pushing the material inside the material dropping cylinder 7 into the material dropping mechanism is arranged on the outer side of the support cylinder 5. The pushing part of the pushing mechanism is also provided with an air flow channel and keeps one end of the air flow channel pointing to the material inside the material dropping cylinder 7, and a positive pressure hose 18 is arranged at the other end. When the pushing mechanism is pushing the material, the positive pressure hose 18 conveys positive pressure air into the air flow channel. A material blocking component for preventing the material from splashing outward is also arranged on the material dropping mechanism.

[0039] 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. The driving device 2 and the transmission mechanism 4 drive the discharge barrel 7 to perform intermittent rotational motion.

[0040] 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 (such as the attached Figure 1 ), or it can be replaced with a grooved wheel transmission mechanism that facilitates intermittent motion.

[0041] Specifically, a baffle 16 is provided between the gap between the inner bottom of the support tube 5 and the bottom of the discharge tube 7 , and a connecting hole corresponding to any discharge hole of the discharge tube 5 is formed on the baffle 16 .

[0042] Specifically, the blanking mechanism includes a blanking baffle 17, which is slidably disposed at the bottom of the support tube 5;

[0043] Several blanking barrels 12 of different sizes are evenly spaced and arranged on the blanking baffle 17 to keep the blanking barrels 12 connected with the connecting holes of the baffle 16;

[0044] The fixing mechanism is movably disposed below the support tube 5 and is used to connect and fix any one of the blanking tubes 12 and the connecting hole of the baffle 16 .

[0045] 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. 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.

[0046] For further information, please refer to the attached Figure 6 and attached Figure 8 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.

[0047] 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.

[0048] Specifically, the bottom of the support tube 5 is fixed to the support body 1 through a support rod 6, and the fixing mechanism is slidably arranged on the outer end of any one of the support rods 6. An adjusting rod 15 is also arranged 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.

[0049] 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.

[0050] 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.

[0051] Please see attached Figure 6 and attached Figure 7 Specifically, a material baffle assembly is provided at the outer end of the fixed cylinder 13, and the material baffle assembly includes a main baffle plate 19 and a side baffle plate 20. The main baffle plate 19 is provided on the fixed plate 14 above the fixed cylinder 13, and the side baffle plate 20 is an arc-shaped plate sleeved on the outside of the fixed cylinder 13 and installed vertically with the main baffle plate 19.

[0052] Specifically, the pushing mechanism includes a mounting plate 8 mounted on the outer side of the top end of the support tube 5 at a position corresponding to the connecting hole;

[0053] A linear telescopic device 9 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;

[0054] A movable plate 10, one end of which is fixed to the telescopic end of the linear telescopic device 9;

[0055] 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 .

[0056] Specifically, the push rod is provided with a central hole to form an air flow channel, and a discharge hose is arranged above the movable plate, and the discharge hose is connected with the air flow channel.

[0057] The material discharge device can blow and push lighter materials downward by arranging an air flow channel and a positive pressure hose in the pushing mechanism. Combined with the material baffle assembly outside the fixed cylinder, it can effectively prevent the material from splashing to the outside, and it is convenient to collect the flying materials together to prevent waste. At the same time, the material discharge device can adjust the material discharge amount according to actual needs by arranging a slidable material discharge baffle in the material discharge mechanism and installing several material discharge barrels of different sizes on the material discharge baffle, so as to facilitate the material discharge operation of different materials or different packaging bag sizes of the same material.

[0058] When adjusting the material discharge amount, the material discharge mechanism first rotates the fastener 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 moves the appropriate blanking cylinder 12 (if the blanking amount is larger, the inner diameter of the blanking cylinder 12 is larger, and vice versa) to the connecting hole position of the baffle 16 according to the required material discharge amount, and then reverses the fastener 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.

[0059] During the unloading process, the unloading device first drives the unloading barrel 7 to rotate one station through the driving device 2, the transmission rod 3 and the transmission mechanism 4, and keeps any unloading hole in the unloading barrel 7 corresponding to the connecting hole of the baffle 16. At this time, the linear telescopic device 9 (which can be set to a cylinder, an electronic push rod, etc. that is easy to automatically control) moves once, driving the push rod 11 to move downward. During this process, the positive pressure hose 18 discharges positive pressure air into the air flow channel through an external air source, blowing the material in the unloading barrel 7 to flow downward through the connecting hole and fall into the unloading barrel 12, and finally fall into the packaging bag. Under the blowing of the positive pressure air, part of the material may splash outward and be blocked by the main baffle 19 and the side baffle 20, and finally fall down naturally, completing the unloading and blocking process of the material.

[0060] 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.
