Description

Technical Field

[0001] This utility model belongs to the field of turnover rack technology, specifically a pre-packaged food turnover rack. Background Technology

[0002] Prepackaged food turnover racks are storage devices designed for prepackaged foods and are widely used in food transportation, warehousing, and distribution. By placing prepackaged foods in the placement frames of the turnover racks, the foods can be moved and transferred by moving the turnover racks, which can reduce storage and transportation costs. At the same time, it makes it easier for managers to quickly locate the required foods and avoid confusion and loss.

[0003] In existing technology, pre-packaged food is neatly placed in a placement frame, and then the placement frame is placed on two sets of support rails in a turnover rack. The pre-packaged food is then moved and transferred by moving the turnover rack. However, if there is an uneven ground during the movement, the turnover rack will bump, and some loose packaged food placed in the placement frame is easily affected by the bumps and falls, resulting in damage. Moreover, the placement frame placed on the support rails is also easily affected by the bumps and moves, resulting in the placement frame being untidy. To address this issue, we propose a pre-packaged food turnover rack. Utility Model Content

[0004] The purpose of this utility model is to provide a pre-packaged food turnover rack to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pre-packaged food turnover rack, comprising a base frame, an upper frame fixed on the base frame, and multiple sets of placement wire mesh frames, wherein the upper frame is provided with a pressing and limiting mechanism, the pressing and limiting mechanism comprising:

[0006] The pressing assembly includes a pressing plate disposed above the mesh frame. A rubber buffer plate is fixedly disposed at the bottom of the pressing plate. A middle plate is fixedly disposed on one side of the base frame. A lower bearing is disposed on the middle plate. A lead screw is fixedly disposed on the inner wall of the lower bearing. Multiple sets of nut seats are evenly distributed on the outside of the lead screw along the length of the lead screw, for driving the pressing plate to move up and down.

[0007] Preferably, the clamping and limiting mechanism further includes an adjustment component, which includes a middle plate fixed to the front and back of the nut seat. A screw is threadedly connected to the inside of the middle plate, and a limiting rod is slidably provided inside the middle plate.

[0008] Preferably, a second mounting plate is fixedly provided at the bottom of the limiting rod, and an upper bearing is provided on the second mounting plate.

[0009] Preferably, a first mounting plate is fixedly provided on the top of one side of the pressure plate, and the first mounting plate and the second mounting plate are fixedly connected by two sets of bolts.

[0010] Preferably, the base frame is provided with a stabilizing component, which includes a counterweight plate disposed on the base frame. The front and back of the counterweight plate are fixedly provided with connecting plates, and the connecting plates are provided with studs inside.

[0011] Preferably, the upper surface of the counterweight plate has two sets of threaded grooves for the bottom of the stud to be screwed into.

[0012] Preferably, multiple sets of support rails are fixedly installed on the base frame, and the placement mesh frame is located on top of the support rails.

[0013] Preferably, the base frame is equipped with casters at all four corners of its bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) Through the designed pressing and limiting mechanism, the rubber buffer plate at the bottom of the pressing plate directly contacts the pre-packaged food placed in the wire mesh frame. The screw body drives the nut seat to rise and fall synchronously, thereby achieving longitudinal pressing of the food, reducing the vertical jumping of the food during bumps, reducing the drop rate of loose packaged food, and also pressing the wire mesh frame. At the same time, the screw and limiting rod in the adjustment component cooperate to support the independent height adjustment of a single pressing plate, which can adapt to different packaging with different heights in the wire mesh frame, and improve the safety and stability of pre-packaged food during turnover.

[0016] (2) By designing a stabilizing component, this utility model can increase the center of gravity of the bottom of the turnover rack when moving and transferring some turnover racks with an excessively high center of gravity. This increases the stability of the turnover rack during the movement and transfer process, making it less likely to tip over due to an unstable center of gravity. Attached Figure Description

Detailed Implementation

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a technical solution: a pre-packaged food turnover rack, including a base frame 100, an upper frame 102 fixed on the base frame 100, and multiple sets of placement wire mesh frames 101. The upper frame 102 is provided with a pressing and limiting mechanism, which includes a pressing component. The pressing component includes a pressing plate 200 disposed above the placement wire mesh frames 101. A rubber buffer plate 203 is fixedly disposed at the bottom of the pressing plate 200. The rubber buffer plate 203 can provide a cushioning effect when in contact with food, reducing the squeezing of the food. Furthermore, the pressing plate 200 and the rubber buffer plate 203 gently press against the pre-packaged food inside the placement wire mesh frames 101. The food is pressed to prevent it from jumping and falling when bumped. A middle plate 210 is fixedly installed on one side of the base frame 100. A lower bearing 209 is installed on the middle plate 210. The lower bearing 209 is composed of an inner ring and an outer ring. During use, the inner ring of the lower bearing 209 is fixedly connected to the bottom outer wall of the lead screw body 202. The lead screw body 202 is fixedly installed on the inner wall of the lower bearing 209. Multiple sets of nut seats 201 are evenly distributed on the outside of the lead screw body 202 and along the length of the lead screw body 202. When the lead screw body 202 rotates, it can drive the multiple nut seats 201 to move up and down synchronously, which is used to drive the pressing plate 200 to move up and down.

[0026] Example 2

[0027] Please refer to Example 1. Figure 2 , Figure 3 and Figure 5 The clamping and limiting mechanism also includes an adjustment component, which includes a middle plate 210 fixed on the front and back of the nut seat 201. The middle plate 210 is connected to a screw 205 by a thread. Rotating the screw 205 can move the lower second mounting plate 207 up and down. A limit rod 206 is also slidably provided inside the middle plate 210.

[0028] A second mounting plate 207 is fixedly installed at the bottom of the limiting rod 206. An upper bearing 208 is installed on the second mounting plate 207. The bottom of the screw 205 extends into the interior of the upper bearing 208. The upper bearing 208 is composed of an inner ring, an outer ring, etc. In use, the inner ring of the upper bearing 208 is fixedly connected to the bottom outer wall of the screw 205, and the bottom of the screw 205 is fixedly connected to the inner wall of the upper bearing 208.

[0029] A first mounting plate 204 is fixedly installed on the top of one side of the pressure plate 200. The first mounting plate 204 and the second mounting plate 207 are fixedly connected by two sets of bolts. When it is not necessary to use the pressure plate 200 to press and limit the pre-packaged food, the pressure plate 200 can be removed. To remove it, simply unscrew the bolts.

[0030] This utility model, through its designed pressing and limiting mechanism, ensures that the rubber buffer plate 203 at the bottom of the pressing plate 200 directly contacts the pre-packaged food placed in the wire mesh frame 101. The screw body 202 drives the nut seat 201 to rise and fall synchronously, achieving longitudinal pressing of the food, reducing vertical jumping of the food during bumps, and reducing the drop rate of loosely packaged food. At the same time, the screw 205 in the adjustment component cooperates with the limiting rod 206 to support independent height adjustment of a single pressing plate 200, which can adapt to different packaging with different heights within the wire mesh frame 101, improving the safety and stability of pre-packaged food during turnover.

[0031] In summary, first, place multiple loose pre-packaged foods into the placement wire mesh frame 101 and arrange them neatly. Then, place the placement wire mesh frame 101 onto the two sets of support rails 104 in the turnover rack. Following the same method, place the remaining placement wire mesh frames 101 onto the support rails 104. Next, rotate the lead screw 202, causing multiple sets of nut seats 201 outside the lead screw 202 to move downwards. The nut seats 201 cause the middle plate 210, the second mounting plate 207, the first mounting plate 204, and the pressure plate 200 to move downwards. Then, the rubber buffer plate 203 at the bottom of the pressure plate 200 contacts and presses the pre-packaged foods placed on the placement wire mesh frame 101, limiting their movement and reducing the probability of loose pre-packaged foods falling off the placement wire mesh frame 101 due to bumps during the movement of the turnover rack.

[0032] Generally, the height of the pre-packaged food in each placement frame 101 is consistent. If the height of the pre-packaged food in adjacent or other placement frames 101 is inconsistent with the height of the food in this placement frame 101, the corresponding pressure plate 200 above the placement frame 101 for the pre-packaged food of different heights can be moved up or down so that it can move synchronously with other pressure plates 200 to press the pre-packaged food in the placement frame 101. During adjustment, the corresponding screw 205 is rotated up or down, driving the upper bearing 208 to move up or down, thereby driving the lower second mounting plate 207 to move. 7 drives the limiting rod 206 to slide up and down within the middle plate 210. When the second mounting plate 207 moves up and down, it also drives the first mounting plate 204 to move. The first mounting plate 204 drives the pressure plate 200 and the rubber buffer plate 203 on the pressure plate 200 to move. Then, it moves up or down to a suitable height and stops. At this time, the distance between the pressure plate 200 and the pre-packaged food with different heights in the lower frame 101 is the same as the distance between the adjacent or other pressure plates 200 and the pre-packaged food in the lower frame 101. After adjustment, the pressure plates 200 at different heights can move up and down synchronously.

[0033] Example 3

[0034] Please refer to Example 2. Figures 1-4 The base frame 100 is provided with a stabilizing component, which includes a counterweight plate 300 provided on the base frame 100. A connecting plate 303 is fixedly provided on both the front and back of the counterweight plate 300, and a stud 301 is provided inside the connecting plate 303.

[0035] The upper surface of the counterweight plate 300 has two sets of threaded grooves for the bottom of the stud 301 to be screwed into, and a retaining ring 302 is fixedly installed on the outside of the stud 301.

[0036] This utility model, through the design of a stabilizing component, allows for the installation of a counterweight plate 300 on the base frame 100 when moving or transferring some turnover racks with excessively high centers of gravity. This increases the center of gravity at the bottom of the turnover rack, thereby increasing its stability during movement and transfer, making it less prone to tipping over due to an unstable center of gravity.

[0037] In summary, when placing heavier pre-packaged foods on top of the turnover rack causes the rack to become unstable due to an excessively high center of gravity during movement, a counterweight plate 300 can be placed from above the base frame 100 at a suitable position. The connecting plate 303 should be aligned with the threaded groove on the base frame 100. Then, the bottom of the stud 301 should be passed through the interior of the connecting plate 303 and screwed into the corresponding threaded groove in the base frame 100, thus fixing the connecting plate 303 to the base frame 100. This counterweight plate 300 increases the weight at the bottom of the turnover rack, thereby raising the center of gravity and reducing the likelihood of instability during movement, thus increasing the stability of the turnover rack during transport.

[0038] In this embodiment, multiple sets of support rails 104 are fixedly installed on the base frame 100, and the mesh frame 101 is located on top of the support rails 104.

[0039] In this embodiment, casters 103 are provided at all four corners of the bottom of the base frame 100, which facilitates the movement of the turnover frame and the transfer of pre-packaged food.

[0040] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
