Description

Technical Field

[0001] This utility model relates to the field of palletizing machine technology, specifically a lifting device for a palletizing machine. Background Technology

[0002] A palletizer is a device that stacks goods in a specific arrangement, capable of stacking multiple layers, facilitating forklift transport to warehouse storage. Palletizers can significantly reduce labor and labor intensity. They automatically stack bags, cartons, or other packaging materials conveyed by a conveyor into pallets according to customer process requirements, and then transport the stacked materials.

[0003] Chinese patent publication number CN211283588U discloses a palletizing machine lifting device. This lifting device drives a rotating sleeve on both sides to rotate synchronously and in the same direction via a drive motor. Spiral grooves are opened on the rotating sleeves, and sliding pins that cooperate with the spiral grooves are installed on the lifting columns fitted inside the rotating sleeves. The rotation of the rotating sleeves drives the lifting columns to move up and down, thereby achieving the lifting function. It has a large transmission ratio and high transmission efficiency. Moreover, through the dual action of synchronous transmission and guide columns, the stability of the lifting plate is greatly improved, avoiding accidents such as side tipping and overturning, and improving safety performance.

[0004] However, when the device is used for palletizing, the turnover boxes need to be placed on the lifting platform and the goods are stacked in the turnover boxes. Since the turnover boxes lack certain fixing measures, they will be slightly offset due to the impact of the goods being stacked during the palletizing process. Repeated stacking will cause the offset distance to become larger and larger, resulting in the stacked goods being deviated, messy, and not neat, thus affecting the quality of the palletizing. Utility Model Content

[0005] The purpose of this invention is to provide a lifting device for a palletizer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lifting device for a palletizer includes: a processing table, a leveling component and a sorting component on the top surface of the processing table, a support frame on one side of the processing table, and a palletizing component on the top surface of the support frame;

[0008] The lifting mechanism is located inside the support frame. The lifting mechanism includes a base plate fixedly installed on the bottom surface of the support frame, two side plates fixedly installed on the inner wall of the support frame, and a placement frame provided above the base plate. The lifting mechanism is used to lift the turnover box.

[0009] The fixing mechanism is located above the base plate and includes two clamping plates that are slidably installed on the inner wall of the placement frame. The two clamping plates are respectively provided with connecting plates at their far ends. The fixing mechanism is used to clamp and fix the turnover box.

[0010] Preferably, the bottom surfaces of the two side plates are fixedly connected to the top surface of the base plate, and two limiting strips are fixedly installed on the sides of the two side plates close to each other. Limiting sleeves are slidably installed on the outer walls of the multiple limiting strips.

[0011] Preferably, the sides of multiple limiting sleeves are fixedly connected to the sides of the placement frame, and threaded sleeves are fixedly installed on both sides of the placement frame.

[0012] Preferably, a fixing plate is fixedly installed on the top surface of each of the two side plates, a motor is fixedly installed on the top surface of each of the two fixing plates, and a threaded rod is fixedly installed on the output end of each of the two motors. The lower ends of the two threaded rods are rotatably connected to the bottom surface of the two fixing plates through the first bearing seat, and the outer walls of the two threaded rods are threadedly connected to the inner walls of the two threaded sleeves.

[0013] Preferably, the bottom surfaces of the two connecting plates are slidably connected to the inner wall of the placement frame, and two support columns are fixedly installed on the two connecting plates respectively away from each other. The other ends of the multiple support columns slide through the inner wall of the placement frame and extend to the outer side of the placement frame. Two fixing strips are fixedly installed on one end of the multiple support columns.

[0014] Preferably, elastic elements are slidably installed on the outer walls of multiple support columns, and the two ends of the multiple elastic elements are respectively fixedly connected to the two fixing strips and the side of the placement frame.

[0015] Preferably, two wedge plates are fixedly installed on the sides of the two side plates close to each other, the sides of the two fixing strips are slidably connected to the sides of the two wedge plates, and two support rods are fixedly installed on the sides of the two clamping plates far from each other.

[0016] Preferably, the other ends of the multiple support rods slide through the two connecting plates and extend to the other side of the connecting plates, with a circular plate fixedly installed on one end of each of the multiple connecting plates. Elastic elements II are slidably installed on the outer walls of the multiple support rods, and the two ends of the multiple elastic elements II are fixedly connected to the sides of the two connecting plates and the sides of the two clamping plates, respectively.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention uses a placement frame to move turnover boxes upwards for stacking, simultaneously moving a fixing strip upwards to contact a wedge plate. The wedge plate continuously presses against the fixing strip, which in turn pushes the support column and connecting plate to move. The connecting plate then moves the support rod and clamping plate, causing the clamping plate to contact and continuously press against the turnover box. The elastic element contracts to apply elastic force to the clamping plate, thus clamping and fixing the turnover box. During the stacking process, the turnover box is less prone to shifting due to the impact of the stacked goods, ensuring that the stacked goods are less likely to deviate or become disordered, thereby improving the quality of stacking.

[0019] By turning on the motor, the threaded rod is driven to rotate, which in turn drives the threaded sleeve and the placement frame to move, thereby causing the placement frame and the turnover box to rise and fall. The limit strip and limit sleeve set up limit the placement frame, making the movement of the placement frame more stable and ensuring that the lifting and lowering of the turnover box is more stable, so that the items inside the turnover box are less likely to shake or shift.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0032] like Figures 1-6 As shown, this application provides a lifting device for a palletizer, including: a processing table 1, a leveling component 101 and a sorting component 102 provided on the top surface of the processing table 1, a support frame 103 provided on one side of the processing table 1, and a palletizing component 104 provided on the top surface of the support frame 103;

[0033] Lifting mechanism 2 is installed inside support frame 103. Lifting mechanism 2 includes a base plate 201 fixedly installed on the bottom surface of support frame 103. Two side plates 202 are fixedly installed on the inner wall of support frame 103. A placement frame 205 is provided above the base plate 201. Lifting mechanism 2 is used to lift the turnover box.

[0034] Specifically, such as Figures 1-3 As shown, the bottom surfaces of the two side plates 202 are fixedly connected to the top surface of the base plate 201. Two limiting strips 203 are fixedly installed on the sides of the two side plates 202 close to each other. Limiting sleeves 204 are slidably installed on the outer walls of the multiple limiting strips 203.

[0035] In this embodiment: the limiting strip 203 is used to limit the limiting sleeve 204, making the sliding of the limiting sleeve 204 on the outer wall of the limiting strip 203 more stable.

[0036] Specifically, such as Figures 1-3 As shown, the sides of multiple limiting sleeves 204 are fixedly connected to the sides of the placement frame 205, and threaded sleeves 208 are fixedly installed on both sides of the placement frame 205.

[0037] In this embodiment, the placement frame 205 is limited by the limiting sleeve 204, making the movement of the placement frame 205 more stable.

[0038] Specifically, such as Figures 1-3 As shown, a fixing plate 206 is fixedly installed on the top surface of the two side plates 202 respectively, and a motor 207 is fixedly installed on the top surface of the two fixing plates 206 respectively. Threaded rods 209 are fixedly installed on the output ends of the two motors 207 respectively. The lower ends of the two threaded rods 209 are rotatably connected to the bottom surface of the bottom plate 201 through the first bearing seat. The outer walls of the two threaded rods 209 are threadedly connected to the inner walls of the two threaded sleeves 208 respectively.

[0039] In this embodiment: the motor 207 drives the threaded rod 209 to rotate, the threaded rod 209 drives the threaded sleeve 208 to move, and the threaded sleeve 208 drives the placement frame 205 to move, thereby adjusting the height of the placement frame 205.

[0040] The fixing mechanism 3 is located above the base plate 201. The fixing mechanism 3 includes two clamping plates 308 that are slidably installed on the inner wall of the placement frame 205. The two clamping plates 308 are respectively provided with connecting plates 301 at their far ends. The fixing mechanism 3 is used to clamp and fix the turnover box.

[0041] Specifically, such as Figures 1-6 As shown, the bottom surfaces of the two connecting plates 301 are slidably connected to the inner wall of the placement frame 205. The two connecting plates 301 are respectively fixedly installed with two support columns 302 on their sides away from each other. The other ends of the multiple support columns 302 slide through the inner wall of the placement frame 205 and extend to the outside of the placement frame 205. Two fixing strips 303 are fixedly installed on one end of the multiple support columns 302.

[0042] In this embodiment: the connecting plate 301 is supported by the supporting column 302, thereby driving the connecting plate 301 to move.

[0043] Specifically, such as Figures 1-6 As shown, elastic elements 304 are slidably installed on the outer walls of multiple support columns 302, and the two ends of the multiple elastic elements 304 are fixedly connected to the two fixing strips 303 close to each other on the side and the side of the placement frame 205 respectively.

[0044] In this embodiment, the elastic element 304 is used to apply elastic force to the fixing strip 303.

[0045] Specifically, such as Figures 1-6 As shown, two side plates 202 are fixedly installed with wedge plates 305 close to each other on their sides, two fixing strips 303 are slidably connected to the sides of the two wedge plates 305 respectively, and two clamping plates 308 are fixedly installed with two support rods 306 away from each other on their sides.

[0046] In this embodiment: the turnover box is clamped and fixed by the clamping plate 308. When the placement frame 205 moves upward, the wedge plate 305 squeezes the fixing strip 303 to move. When the placement frame 205 moves downward, the elastic element 304 pushes the fixing strip 303 back to its original position, and the clamping plate 308 no longer clamps the turnover box.

[0047] Specifically, such as Figures 1-6 As shown, the other ends of multiple support rods 306 slide through two connecting plates 301 and extend to the other side of the connecting plates 301. A circular plate 307 is fixedly installed on one end of each of the multiple connecting plates 301. Elastic elements 309 are slidably installed on the outer walls of the multiple support rods 306. The two ends of the multiple elastic elements 309 are fixedly connected to the sides of the two connecting plates 301 and the sides of the two clamping plates 308, respectively.

[0048] In this embodiment: the elastic element 309 applies elastic force to the clamping plate 308, thereby fixing the clamping plate 308 to the turnover box.

[0049] Specifically, this solution involves activating motor 207, which rotates threaded rod 209. Threaded rod 209 then moves threaded sleeve 208 and placement frame 205, thereby raising and lowering placement frame 205 and the turnover box. Limiting strip 203 and limiting sleeve 204 limit the placement frame 205, ensuring smoother movement and more stable lifting of the turnover box. This prevents items inside the turnover box from shaking or shifting. Simultaneously, when placement frame 205 moves the turnover box upwards for stacking, it also moves fixing strip 303 upwards to engage with the wedge plate. When the wedge plate 305 contacts the fixed strip 303, the fixed strip 303 pushes the support column 302 and the connecting plate 301 to move. The connecting plate 301 drives the support rod 306 and the clamping plate 308 to move. The clamping plate 308 contacts the turnover box and continues to press it. The elastic element 309 contracts and applies elastic force to the clamping plate 308, so that the clamping plate 308 clamps and fixes the turnover box. During the stacking process, the turnover box is not easy to deviate from the impact of the stacked goods, ensuring that the stacked goods are not prone to deviation and disorder, thereby improving the quality of stacking.

[0050] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0051] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
