Abstract
Description
Technical Field
[0001] The utility model relates to a lifting and feeding device, belonging to the technical field of automatic feeding equipment. Background Art
[0002] The lifting device is a kind of mechanical equipment widely used in the material handling and conveying process. It lifts the material from a lower position to a higher position through mechanical lifting so as to carry out the next processing or filling. The design of the lifting device makes the material transfer process more efficient and hygienic, and also reduces the labor intensity of manual handling.
[0003] However, in the process of lifting materials by the lifting platform, the materials are prone to shaking, which causes changes in their position and posture. This requires the next mechanism to have higher accuracy and adaptability when grabbing the materials, resulting in increased production costs.
[0004] In order to solve the problem of material shaking during the lifting process, a common method is to install an adjustment mechanism on the lifting and feeding device to hold the outer edge of the material and provide stable support. However, in order for the adjustment mechanism to achieve the adjustment function, the size of the lifting platform generally needs to be smaller than the material to facilitate the movement of the adjustment mechanism to hold the outer edge of the material. In this way, part of the material is suspended in the air. During the lifting process, when the material shakes, the adjustment mechanism is subjected to a large impact force, which is easy to cause damage, thereby increasing maintenance costs. Utility Model Content
[0005] The utility model aims to provide a lifting and loading device which can reduce the shaking of materials.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lifting and feeding device, comprising:
[0007] Pedestal;
[0008] A lifting platform is arranged on the upper surface of the base to carry materials, and a plurality of avoidance holes are formed on the outer edge of the lifting platform;

[0016] A driven wheel is arranged at an end of the screw rod away from the jacking platform;
[0017] A transmission belt connecting the driving wheel and the driven wheel; and
[0018] The lifting member is slidably arranged on the screw rod and connected to the lifting platform.
[0019] Furthermore, the lifting member moves along the axial direction of the screw rod to form a first position and a second position, and the base is provided with a limit origin sensor at the same horizontal height of the first position and the second position.
[0020] Furthermore, the lifting member comprises:

Secondly, through the cooperation between the fixed block and the avoidance hole, the accurate insertion of the adjustment mechanism is realized, and because the adjustment mechanism can be inserted into the avoidance hole to support the outer edge of the material, the size of the lifting platform can be larger than the material size, providing a wider support area for the material, and further enhancing the stability and safety of the material during transportation.

[0032] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] See also Figure 1 and Figure 2 The jacking and loading device 100 shown in a preferred embodiment of the present application includes a base 1, a jacking platform 2, a driving mechanism 3 and an adjusting mechanism 4.
[0037] The base 1 not only provides physical support for the lifting and loading device 100 to ensure the stability of the mechanical operation, but also provides a fixed position for the lifting platform 2, the driving mechanism 3 and the adjusting mechanism 4, and is a framework for connecting and integrating various mechanical components.
[0038] The jacking platform 2 is arranged on the upper surface of the base 1 to carry the material. A plurality of avoidance holes 21 are formed on the outer edge of the jacking platform 2, so that the adjustment mechanism 4 can be inserted into the jacking platform 2 through the avoidance holes 21, thereby adapting to materials of different sizes and shapes. In addition, the presence of the avoidance holes 21 also helps to reduce the weight of the jacking platform 2, improve the jacking speed and efficiency, and also facilitate the maintenance and cleaning of the platform, maintaining the efficiency and stability of the long-term operation of the jacking and feeding device 100.
[0039] The lower surface of the lifting platform 2 is provided with a material shortage sensor 22 for real-time monitoring of the material status on the lifting platform 2. When the material is completely taken away or is in a material shortage state, the material shortage sensor 22 can detect this state in time and send a signal, and through interaction with the control system (not shown), it can automatically trigger the material replenishment program or send an alarm to remind the operator to replenish the material.
[0040] The driving mechanism 3 is disposed on the lower surface of the base 1 to drive the lifting platform 2 to move in the vertical direction. In this embodiment, the driving mechanism 3 includes a servo motor 31, a driving wheel 32, a screw rod 33, a driven wheel 34, a transmission belt 35 and a lifting member 36.
[0041] The servo motor 31 is fixed on the base 1 to provide power for the lifting and loading device 100, and the high-precision positioning of the lifting platform 2 can be guaranteed through the precise control of the servo motor 31, so as to meet the delicate operation of handling different materials. The driving wheel 32 is arranged on the output shaft of the servo motor 31, the screw rod 33 is installed on the base 1, and is arranged adjacent to the servo motor 31, the driven wheel 34 is arranged at the end of the screw rod 33 away from the lifting platform 2, the transmission belt 35 connects the driving wheel 32 and the driven wheel 34, and the lifting member 36 is slidably arranged on the screw rod 33 and connected to the lifting platform 2. Therefore, the rotational power of the servo motor 31 can be effectively transmitted to the screw rod 33 through the interaction of the driving wheel 32, the transmission belt 35 and the driven wheel 34, thereby driving the lifting member 36 to move along the axial direction of the screw rod 33.
[0042] The lifting member 36 moves along the axial direction of the screw rod 33 to form a first position and a second position, which represent the two extreme states of the lifting platform 2 within its range of motion, corresponding to the lowest point and the highest point of the movement of the lifting platform 2. In order to ensure that the lifting member 36 can stop accurately when it reaches these two extreme positions and avoid damage caused by excessive movement, the base 1 is provided with an extreme origin sensor 37 at the same horizontal height of the first position and the second position to detect the position of the lifting member 36 and send a signal to the control system when it reaches the preset first position or second position. After receiving this signal, the control system will immediately instruct the servo motor 31 to stop moving, thereby ensuring that the lifting member 36 stops stably at the correct position.
[0043] The lifting member 36 includes a moving plate 361, a connecting rod 362 and a resisting portion 363. The moving plate 361 is slidably arranged on the screw rod 33, the connecting rod 362 is arranged on the moving plate 361 along the axial direction of the screw rod 33, and the top end of the connecting rod 362 protrudes from the upper surface of the base 1, and the resisting portion 363 connects the top end of the connecting rod 362 and the lower surface of the lifting platform 2.
[0044] In another embodiment, the driving mechanism 3 can be powered by a cylinder or a linear motor, and the jacking platform 2 is directly connected to the cylinder or the linear motor. In this way, the installation complexity of the device can be simplified, but the control accuracy during the jacking process will be reduced.
[0045] The adjusting mechanism 4 is arranged along the outer edge of the jacking platform 2, and a fixing block 5 is arranged at the bottom of the adjusting mechanism 4, and the upper surface of the fixing block 5 is not higher than the upper surface of the jacking platform 2, so that the material can be placed flatly on the jacking platform 2 to avoid interference or damage to the material during transportation. In this embodiment, the fixing block 5 is L-shaped. On the one hand, the fixing block 5 can support the adjusting mechanism 4 to prevent the adjusting mechanism 4 from shaking, and on the other hand, the adjusting mechanism 4 can move relative to the base 1. When the adjusting mechanism 4 is close to the base 1, the fixing block 5 can guide the adjusting mechanism 4 to be inserted into the avoidance hole 21.
[0046] The adjusting mechanism 4 includes a first bracket 41 and a second bracket 42 which are arranged opposite to each other, and a third bracket 43 and a fourth bracket 44 which are arranged opposite to each other. The first bracket 41, the second bracket 42, the third bracket 43 and the fourth bracket 44 extend in a vertical direction. The first bracket 41, the second bracket 42, the third bracket 43 and the fourth bracket 44 are distributed on the outer edge of the jacking platform 2.
[0047] In this embodiment, the first bracket 41 is fixed to the upper surface of the base 1, and the second bracket 42, the third bracket 43 and the fourth bracket 44 can slide relative to the base 1. Specifically, a slider slot structure is provided at the bottom of the second bracket 42, the third bracket 43 and the fourth bracket 44. The specific structure of the slider slot structure is relatively common in the prior art and will not be described in detail here.
[0048] In another embodiment, the first bracket 41, the second bracket 42, the third bracket 43 and the fourth bracket 44 may not be fixed on the upper surface of the base 1, but may be arranged adjacent to the base 1, and the first bracket 41, the second bracket 42, the third bracket 43 and the fourth bracket 44 can slide relative to the base 1 to support the outer edge of the material.
[0049] Material arrival sensors 42 for detecting materials are disposed on the second bracket 42 and the fourth bracket 44 to detect whether the materials have reached the designated position during the lifting process, so as to ensure that the materials can be smoothly grasped by the next mechanism.
[0050] The working process of the lifting and loading device 100 is as follows: the material is placed on the lifting platform 2, the material shortage sensor 22 detects that there is material on the lifting platform 2, controls the adjustment mechanism 4 to support the outer edge of the material, starts the driving mechanism 3, and lifts the lifting platform 2 from the first position to the second position. The material arrival sensor 421 detects that the material has arrived at the specified position, transmits a signal, and allows the next mechanism to grab it.
[0051] The present application realizes stable clamping of materials of different sizes through the sliding adjustment mechanism 4, ensures the stability of the materials during the lifting process, and effectively reduces the shaking of the materials. Secondly, through the cooperation between the fixed block 5 and the avoidance hole 21, the accurate insertion of the adjustment mechanism 4 is realized, and because the adjustment mechanism 4 can be inserted into the avoidance hole 21 to support the outer edge of the material, the size of the lifting platform 2 can be larger than the material size, providing a wider support area for the material, and further enhancing the stability and safety of the material during transportation.
[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
