Description

Technical Field

[0001] This utility model relates to the field of food production and processing technology, specifically to an automated food processing equipment, particularly an automatic clamping device for clamping and transferring frying baskets. Background Technology

[0002] With societal progress and increasing automation, many food industries are now using automated or semi-automated food processing machinery. In order to improve food service efficiency, reduce the workload of staff, and minimize potential dangers, some fast food restaurants are starting to use automated food processing equipment. In automatic frying machines, the automated process needs to be stable and reliable, and the equipment needs to be able to complete tasks continuously to ensure that food service is not affected.

[0003] In frying equipment, the primary task is frying the raw materials in the fryer, which is also the main potential hazard for workers. Therefore, the smoothness of the process of placing the frying basket into the fryer and removing it from the fryer is crucial in automated frying. Modern automated processing equipment often uses automatic mechanical grippers to move the frying basket. This requires the stability and reliable structure of the automatic mechanical grippers to accurately hold the frying basket and prevent it from falling off during movement, ensuring the smooth completion of the entire process. If the grippers cannot hold the basket accurately, or if they fall off after being gripped, not only will the work not be completed smoothly, but it may also cause potential dangers.

[0004] Most grippers currently used are cross-opening grippers. While these grippers can hold the frying basket and have a certain degree of stability, the two end grippers rotate around the center, which can cause some interference between the two ends. This can be limiting when there are small gaps and limited dimensions between multiple frying slots, and can also cause the frying basket to slide on both sides, preventing the grippers from accurately placing the basket in the designated position. This can lead to failure in the feeding process, affecting not only the food service but also potentially causing danger. Utility Model Content

[0005] The purpose of this invention is to solve the problems of low stability, unstable gripping, and inaccurate gripping of the automatic grippers in the current automated frying equipment in restaurants, and to propose an automatic gripping device.

[0006] The objective of this utility model can be achieved through the following technical solutions: An automatic clamping device includes: a housing; and a clamping assembly disposed within the housing. The clamping assembly includes: a lead screw; at least two sliding nuts threadedly connected to the lead screw; The crossbeams are arranged on both sides of the lead screw, and the crossbeams are rotatably connected to the corresponding sliding nuts through support arms; Multiple sets of limiting sleeves are fixed to the side wall of the housing. Each set of limiting sleeves has a guide rod that slides through it. The tail of the guide rod is rotatably connected to the crossbeam, and the head is provided with a clamp for pressing and holding the object. A drive unit disposed within the housing for driving the lead screw to rotate.

[0007] As a further embodiment of this utility model: the two sliding nuts are symmetrically arranged on the lead screw, and can move towards or away from each other along the length of the lead screw.

[0008] As a further embodiment of this utility model: a fixing block is also fixed inside the housing, and one end of the lead screw is rotatably inserted into the fixing block.

[0009] As a further embodiment of this utility model: the driving unit includes a driving motor, and the output end of the driving motor is provided with a second pulley; the other end of the lead screw is fixed with a first pulley; the first pulley and the second pulley are connected by a transmission component.

[0010] As a further embodiment of this utility model: a limiter is also provided inside the housing, and the trigger part of the limiter is provided corresponding to the tail of the guide rod.

[0011] As a further embodiment of this utility model: the clamp is an inwardly concave arc-shaped structure, used to press against and lift the rod-shaped component on the object being clamped from both sides.

[0012] This utility model designs a parallel telescopic clamping mechanism consisting of a lead screw, sliding nut, support arm, crossbeam, and guide rods. Its advantages are as follows: First, multiple guide rods move in a strictly linear fashion under the constraint of the limiting sleeve, achieving parallel clamping and lifting of the object (such as the side rod of a blasting basket), avoiding the end-interference problem of traditional cross-rotating grippers, and is particularly suitable for multi-station environments with limited space. Second, this purely mechanical linkage structure provides precise transmission and consistent response, ensuring synchronous and equidistant movement of the guide rods on both sides, thereby stabilizing the clamping center and greatly improving clamping stability and repeatability, effectively preventing objects from sliding or falling off during movement. Finally, the overall structure is simple and reliable; a single drive unit can control multi-point, multi-directional clamping actions, resulting in low manufacturing costs and convenient maintenance, significantly improving the reliability and safety of automated processing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 2-6 As shown, this utility model is an automatic clamping device, including a housing 1. A clamping assembly 5 is provided inside the housing 1. The clamping assembly 5 is used to clamp and limit the frying basket 8. The clamping assembly 5 includes a lead screw 502 and at least two sliding nuts 504. The sliding nuts 504 can move synchronously on the lead screw 502. The sliding nuts 504 are threadedly connected to the lead screw 502. The two sliding nuts 504 are symmetrically arranged in a straight line on the lead screw 502. The sliding nuts 504 can move along the length of the lead screw 502.

[0018] Two crossbeams 506 are provided on both sides of the lead screw 502. The crossbeams 506 are rotatably connected to the sliding nuts 504 through support arms 505. There are multiple sets of support arms 505, with two support arms in each set. One end of each support arm 505 is rotatably connected to two symmetrical sliding nuts 504, while the other end is rotatably connected to the crossbeams 506 together.

[0019] Multiple sets of limiting sleeves 508 are fixed on the side wall of the housing 1. The limiting sleeves 508 can be barrel-shaped. Guide rods 507 are slidably inserted into each of the multiple sets of limiting sleeves 508. The tail of the guide rod 507 is rotatably connected to the crossbeam 506. The head of the guide rod 507 is provided with an inwardly recessed clamp 509. The clamp 509 is used to press and limit the frying basket 8. The housing 1 is also provided with a driving part 4 for driving the lead screw 502 to rotate.

[0020] A fixing block 501 is also fixed inside the housing 1, and one end of the lead screw 502 is inserted into the fixing block 501 and rotates. The other end of the lead screw 502 is fixed to a first pulley 503. The driving part 4 is a drive motor, and a second pulley is fixed to the output end of the drive motor. The first pulley 503 and the second pulley are connected by a transmission component.

[0021] Based on any of the above embodiments, a limiter 3 is also installed inside the housing 1, and the trigger part of the limiter 3 is located at the tail of the guide rod 507. Specifically, the limiter 3 is fixed to the housing 1 by a bracket 101.

[0022] Please see Figure 1 and Figure 7 Furthermore, the automatic clamping device of this invention can be mounted on an external moving mechanism 7 via a connecting part (such as a connecting rod 2) on its housing 1, thereby enabling movement along paths such as the guide rail 6 to complete clamping and transfer tasks. When the moving mechanism 7 moves on the guide rail 6, it can drive the frying basket 8 to move through the clamping device.

[0023] The working principle of this utility model is as follows: As shown in the figure, the shell 1 in the clamping device is rectangular in shape. There are two guide rods 507 on each side of the rectangular shell 1 that can be horizontally retracted from the limiting sleeve 508. The heads of the guide rods 507 extend and retract horizontally to clamp and lift the railings on both sides of the frying basket 8 from the inside, and move the whole through the guide rods 507.

[0024] The overall movement is initially driven by a drive motor. A pulley is installed on the output side of the drive motor, and below the pulley is a parallel pulley. The two pulleys are the first pulley 503 and the second pulley. After the upper pulley is driven to rotate by the motor, it drives the lower pulley to rotate through the belt drive, which in turn rotates the lead screw 502 connected to the lower pulley. The lead screw 502 has two sections of threads with opposite directions at both ends. When the lead screw 502 rotates, the sliding nuts 504 on both sides move towards the middle. Through the support arm 505 and the crossbeam 506, it pushes the guide rod 507 to move horizontally. Since the lead screws 502 on both sides rotate synchronously and the threads change in the same way, the sliding nuts 504 move the same distance. Therefore, the guide rods 507 on both sides move the same distance, thus accurately and stably clamping the frying basket 8.

[0025] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
