Description

Technical Field

[0001] This utility model relates to the field of mechanical gripping technology for plastic tableware, and in particular to a clamp for a mechanical gripping arm for plastic tableware. Background Technology

[0002] Tableware refers to non-edible utensils that come into direct contact with food during meals, serving as containers and tools to assist in the distribution or consumption of food. In the processing of plastic tableware, mechanical gripping arms are generally used to move the tableware, reducing the workload of processing personnel and improving processing efficiency. The ends of these gripping arms are typically fitted with clamps to hold the plastic tableware. Currently, existing clamps generally have two jaws that directly grip the wall of the plastic tableware, making them simple and convenient to use. However, this single-point gripping results in poor stability and a tendency for the tableware to loosen. Furthermore, some plastic tableware has thin walls, leading to fewer stress points and increased risk of breakage during movement. Existing designs have addressed these shortcomings; for example, application number 202222591230.2 discloses a plastic tableware machine. A mechanical gripper for plastic tableware includes a fixed base and a control assembly. The fixed base has a support plate fixedly connected to its lower end. External grippers are slidably connected to the end of the groove on the arc surface of the support plate away from its axis, and internal grippers are slidably connected to the end of the groove on the arc surface of the support plate near its axis. The control assembly includes a first sliding column, a second sliding column, a rotating shaft, and a synchronizer. The first sliding column is located at the upper end of the external grippers, and the second sliding column is located at the upper end of the internal grippers. The rotating shaft is located in the middle of the groove on the arc surface of the support plate via a support plate. The outer arc surface of each rotating shaft is rotatably connected to a synchronizer. Both the first and second sliding columns are slidably connected to adjacent synchronizer plates. This mechanical gripper for plastic tableware can grip multiple points simultaneously, both internally and externally, providing good gripping effect and is simple and convenient to use. The aforementioned patent discloses a mechanical gripper for plastic tableware, which, by setting multiple grippers, can achieve simultaneous internal and external gripping at multiple points, improving gripping stability. However, it still has the following shortcomings in use: 1. The distance between two opposing grippers is fixed, which means it can only be used to grip plastic tableware of the same size, limiting its applicability; 2. The gripping force is uncontrollable, posing a risk of damaging the plastic tableware due to excessive gripping force. Considering the above, this application proposes a mechanical gripper for plastic tableware. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1 A clamp for a plastic tableware mechanical gripping arm, including a mounting base 1, with a connecting shaft fixedly connected to the top of the mounting base 1.

[0016] In this implementation plan: Existing device application number: 202222591230.2 discloses a clamp for a mechanical gripping arm for plastic tableware; to solve the technical problems existing in this prior art, such as the "1. The distance between the two opposing grippers is fixed, which makes it only applicable to gripping plastic tableware of the same specification, thus limiting its scope of application; 2. The gripping force is uncontrollable, and there is a risk of damaging the plastic tableware due to excessive gripping force" in combination with the use, this problem is obviously a real and difficult problem to solve. Therefore, in order to solve this technical problem, this application redesigns the clamp for a mechanical gripping arm for plastic tableware.

[0017] It should be noted that the principle of connecting the connecting shaft to the external mechanical gripping arm is existing technology. It can be connected to the mechanical gripping arm by welding a perforated mounting plate. The specific connection is a routine operation for those skilled in the art and will not be elaborated here.

[0018] Furthermore: Reference Figure 1-3 A gripper for a mechanical gripping arm for plastic tableware, including: The pressure-controlled clamping mechanism 2 consists of four sets, which are respectively located on the left, right, front and rear sides of the mounting base 1. The pressure-controlled clamping mechanism 2 is used to control the pressure of plastic tableware. Synchronous control switch 5 is fixedly connected to the top of mounting base 1 and electrically connected to four pressure-controlled clamping mechanisms 2. Synchronous control switch 5 has a built-in wireless remote control module, which is matched with an external remote control. Synchronous control switch 5 is used to control the four pressure-controlled clamping mechanisms 2 to open synchronously. The wireless remote control module and the external remote control can work together to remotely control synchronous control switch 5. The PLC controller 6 is fixedly connected to the top of the mounting base 1 and electrically connected to the synchronous control switch 5 and the pressure clamping mechanism 2; The pressure-controlled clamping mechanism 2 includes L-shaped clamping plates 201, with two L-shaped clamping plates 201 symmetrically arranged opposite each other. A second anti-slip rubber is adhered and fixed to the inner wall of the side of the L-shaped clamping plate 201 away from the mounting base 1. An electric slide rail 202 is fixedly installed on the top inner wall of the L-shaped clamping plate 201. All four electric slide rails 202 are electrically connected to the synchronous control switch 5. A movable seat 203 is fixedly connected to the bottom of the sliding end of the electric slide rail 202. The electric slide rail 202 is used to drive the corresponding movable seat 203. A first clamping plate 204 is provided on the side of the movable seat 203 away from the mounting base 1. A first anti-slip rubber is adhered and fixed to the side of the first clamping plate 204 away from the corresponding movable seat 203. The second anti-slip rubber cooperates with the corresponding first anti-slip rubber to increase the friction during clamping and reduce slippage during clamping. A pressure sensor 205 is embedded and fixed on the side of the movable seat 203 away from the mounting base 1. The monitoring end of 05 is fixedly connected to the corresponding first clamping plate 204. The pressure sensor 205 is used to detect the squeezing force during clamping. All four pressure sensors 205 are electrically connected to the PLC controller 6. The PLC controller 6 receives the data from the pressure sensors 205 to control the synchronous control switch 5. The principle is existing technology and will not be described in detail here. Two positioning rods 206 are fixedly connected to the side of the first clamping plate 204 near the corresponding moving seat 203. The moving seat 203 is slidably sleeved on the two corresponding positioning rods 206. The positioning rods 206 guide the corresponding first clamping plate 204. The side of the moving seat 203 away from the mounting seat 1 has a groove and two guide grooves. The groove is located between the two corresponding guide grooves. The inner wall of the groove away from its opening is fixedly connected to the corresponding pressure sensor 205. The inner wall of the guide groove is in sliding contact with the outer side of the corresponding positioning rod 206.

[0019] In this implementation scheme: when the four sides of the plastic tableware are in contact with the corresponding second anti-slip rubber, all four movable seats 203 are located inside the plastic tableware. The synchronization control switch 5 is activated via an external remote control and a wireless remote control module. The synchronization control switch 5 controls the four electric slide rails 202 to open synchronously in the forward direction. The sliding end of the electric slide rail 202 drives the corresponding movable seat 203 to move closer to the plastic tableware. The movable seat 203, through the corresponding pressure sensor 205, drives the first clamping plate 204 to move. The first clamping plate 204 then drives the corresponding first anti-slip rubber to move to... When in contact with the inside of the plastic tableware, the first anti-slip rubber and the first clamping plate 204 are restricted from moving further. At this time, the moving seat 203 continues to move, which drives the corresponding pressure sensor 205 to squeeze the first clamping plate 204. The pressure sensor 205 detects the squeezing force and transmits the detected squeezing force to the PLC controller 6. When the pressure value is detected to reach the set value, the PLC controller 6 controls the four electric slide rails 202 to close synchronously through the synchronous control switch 5, thereby achieving the purpose of synchronously driving the four first clamping plates 204 to clamp the plastic tableware at multiple points.

[0020] It should be noted that the connection between the PLC controller 6 and the pressure sensor 205 and the synchronous control switch 5 is all electricalally connected via wires. The connection between the synchronous control switch 5 and the four electric slide rails 202 is also via wires. The synchronous control switch 5 is connected in parallel with the driver inside the four electric slide rails 202. The PLC controller 6 presets a control setpoint. The pressure sensor 205 outputs an analog signal to the PLC controller 6 based on the detected pressure value. The PLC controller 6 reads the signal from the pressure sensor 205 and, through logical judgment, outputs a PWM signal to control the synchronous control switch 5 to close the four electric slide rails 202 when the setpoint is reached. The specific control principle is existing technology and will not be elaborated here. The electric slide rail 202 is a linear motion module, which typically includes a guide rail, a slider, a drive motor, and a transmission mechanism. These are mature electrical components available on the market. Furthermore, the principle by which the electric slide rail 202 drives the moving seat 203 to move is also existing technology, and will not be elaborated here.

[0021] Furthermore: The clamp for the plastic tableware mechanical gripping arm also includes a threaded drive mechanism 3, which consists of two sets, both mounted on the mounting base 1. The pressure control clamping mechanism 2 is sleeved on the corresponding threaded drive mechanism 3, and the threaded drive mechanism 3 is used to drive the corresponding pressure control clamping mechanism 2. The threaded drive mechanism 3 includes two screws 301 with opposite thread directions. The ends of the two screws 301 are fixedly connected to each other. Mounting holes are provided on the left and front sides of the mounting base 1. The screws 301 are rotatably mounted in the corresponding mounting holes. Two first bearings are fixedly fitted inside the mounting holes. The inner ring of each first bearing is fixedly connected to the outer side of the corresponding screw 301. The first bearings provide a means for the corresponding screw 301 to rotate. An L-shaped clamping plate 201 is threaded onto the corresponding screw 301. One side of the L-shaped clamping plate 201 has a threaded hole for threaded connection with the corresponding screw 301. This threaded connection allows the L-shaped clamping plate 201 to move laterally while the screw 301 rotates. The screws 301 located on the right and front sides... A square rod 302 is slidably fitted at one end. The right end of the right screw 301 and the front end of the front screw 301 are provided with square grooves. The inner wall of the square groove slides in contact with the outer side of the corresponding square rod 302. The square rod 302 can drive the corresponding screw 301 to rotate through the engagement of the edges. The L-shaped clamp 201 on the right side and the L-shaped clamp 201 on the front side are respectively rotated and sleeved on the corresponding square rod 302. The threaded hole on the right side and the threaded hole on the front side are fixedly sleeved with a second bearing. The inner side of the inner ring of the second bearing is fixedly connected to the outer side of the corresponding square rod 302. The second bearing serves to allow the corresponding square rod 302 to be rotated and installed. The right end of the right square rod 302 and the front end of the front square rod 302 are fixedly connected with a knob. The two screws 301 that are opposite each other are located below the two screws 301 that are opposite each other. The guide mechanism 4 consists of four sets, which are fixedly connected to the left, right, front and rear sides of the mounting base 1, and are fixedly connected to the corresponding pressure control and clamping mechanism 2. The guide mechanism 4 guides the corresponding pressure control and clamping mechanism 2. The guiding mechanism 4 includes guide rods 401. Four guide rods 401 are fixedly connected to the left, right, front and rear sides of the mounting base 1, respectively. Guide blocks 402 are slidably sleeved on the guide rods 401. One side of the guide block 402 has a guide hole that slides and fits with the outer side of the corresponding guide rod 401. The bottom of the guide block 402 is fixedly connected to the top of the corresponding L-shaped clamp 201. The guide block 402 and the guide rods 401 cooperate to provide lateral guidance for the corresponding L-shaped clamp 201.

[0022] In this implementation scheme: When adjusting the distance between the two opposing second anti-slip rubber sheets according to the length and width of the plastic tableware, turning the knob drives the corresponding square rod 302 to rotate. Under the action of the square groove opened on the corresponding screw 301, the square rod 302 rotates and drives the corresponding screw 301 to rotate through the engagement of the square groove's edges. The screw 301 drives the screw 301 connected to it to rotate. Since the threads of the two opposing screws 301 turn in opposite directions, the two opposing L-shaped clamps 201 move in a direction away from or close to each other while the two opposing screws 301 rotate. The L-shaped clamps 201 drive the corresponding second anti-slip rubber sheets to move. When the distance between the two opposing second anti-slip rubber sheets is the same as the size of the plastic tableware, the knob is stopped.

[0023] Working Principle: During use, it can be connected to a mechanical gripping arm via a connecting shaft. Before gripping plastic tableware, the distance between the two opposing second anti-slip rubber sheets is adjusted according to the length and width of the tableware. During adjustment, turning the knob drives the corresponding square rod 302 to rotate. Under the action of the square groove on the corresponding screw 301, the square rod 302 rotates while simultaneously driving the corresponding screw 301 to rotate through the engagement of the square groove's edges. This screw 301 then drives the screw 301 connected to it to rotate. Since the threads of the two opposing screws 301 turn in opposite directions, the rotation of the two opposing screws 301 simultaneously drives the two opposing L-shaped clamps 201 to move towards each other. As the L-shaped clamp 201 moves away from or towards each other, it moves the corresponding second anti-slip rubber. When the distance between the two opposite second anti-slip rubbers is the same as the size of the plastic tableware, the knob is stopped. After adjustment, subsequent gripping operations can be performed. Since the plastic tableware in the same batch has the same specifications, only one adjustment is needed when gripping the same batch of plastic tableware. When gripping another batch of plastic tableware with different specifications, the adjustment can be repeated. The adjustable distance between the two opposite anti-slip rubbers makes it suitable for gripping plastic tableware of different specifications, thus improving its applicability. During the gripping process, when the mechanical gripping arm drives the entire clamp to the position of the plastic tableware, and the four sides of the plastic tableware contact the corresponding second anti-slip rubber, the movement of the entire clamp stops. At this time, all four moving seats 203 are inside the plastic tableware. Then, the synchronization control switch 5 is activated via an external remote control and wireless remote control module. The synchronization control switch 5 controls the four electric slide rails 202 to open synchronously in the forward direction. The sliding end of the electric slide rail 202 drives the corresponding moving seat 203 to move closer to the plastic tableware. The moving seat 203, through the corresponding pressure sensor 205, drives the first clamping plate 204 to move. When the first clamping plate 204 drives the corresponding first anti-slip rubber to contact the inner side of the plastic tableware, the movement of the first anti-slip rubber and the first clamping plate 204 is restricted. The moving seat 203 continues to move, driving the corresponding pressure sensor 205 to squeeze the first clamping plate 204. The first clamping plate 204 squeezes and clamps the plastic tableware through the corresponding first anti-slip rubber. The pressure sensor 205 detects the squeezing force and transmits the detected squeezing force to the PLC controller 6. When the pressure value is detected to reach the set value, the PLC controller 6 controls the four electric slide rails 202 to close synchronously through the synchronous control switch 5, thereby achieving the purpose of synchronously driving the four first clamping plates 204 to clamp the plastic tableware at multiple points with controlled pressure. Moreover, the four first clamping plates 204 and the four L-shaped clamping plates 201 can also achieve synchronous clamping at multiple points on the inside and outside. Through controlled pressure clamping, the risk of damaging the plastic tableware due to large clamping force can be effectively reduced, and the clamping stability can be improved. After clamping, the entire clamp and the clamped plastic tableware can be moved to the designated position by the mechanical gripping arm. When it is necessary to release the clamp on the plastic tableware, the four electric slide rails 202 are opened in the opposite direction by the synchronous control switch 5. Similarly, the operating principle is the opposite of the forward opening, so that the four first clamping plates 204 move towards the mounting base 1, release the clamp on the plastic tableware, and the plastic tableware can be removed.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
