Description

Technical Field

[0001] This utility model relates to the field of weighing and rejection technology, and in particular to a shower gel weighing and rejection machine. Background Technology

[0002] Weighing rejection machines are widely used automated equipment in industrial production. They are primarily used to weigh products on the production line and reject those that do not meet weight standards, ensuring product quality stability and consistency. In the production of shower gel, the application of weighing rejection machines is particularly important due to the diversity of product specifications and the stringent quality requirements. Through precise weight detection and rejection mechanisms, shower gel samples that do not meet weight standards can be effectively identified and rejected, thereby ensuring product quality and safety, and improving production efficiency and economic benefits.

[0003] However, existing weighing rejection machines typically use cylinders to directly push out non-conforming samples from the conveyor line, which presents certain problems. Specifically, because the instantaneous pushing force generated by the direct pushing method is limited, to ensure that even heavier samples can be successfully rejected from the conveyor line, the piston of the cylinder needs to move from one side of the conveyor line to the other to ensure that the piston completely pushes the non-conforming sample away from the conveyor line. This necessitates the use of cylinders with longer strokes. The longer stroke naturally increases the time required to complete one rejection operation. Consequently, the conveyor line needs to reduce its conveying speed to accommodate the rejection operation, thus limiting the conveyor line's speed and consequently restricting the improvement of production efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a shower gel weighing and rejection machine, which aims to improve the instantaneous driving force of the drive device during the rejection operation, so as to shorten the stroke of the drive device, reduce the time required to complete one rejection operation, and thus improve the overall production efficiency.

[0005] To achieve the above objectives, the present invention proposes a shower gel weighing and rejection machine, comprising:

[0006] A conveying device for conveying a shower gel sample from a weighing area to a rejection area along a first direction;

[0007] A rejection drive device is disposed in the rejection area and located on one side of the conveying device;

[0008] An elastic push plate, one side of which is connected to the rejection drive device;

[0009] An energy storage baffle is disposed on the other side of the elastic push plate between the conveying device;

[0010] A collection bin is located in the rejection area and on the other side of the conveying device;

[0011] The rejection drive device is used to drive the elastic push plate to move along the second direction; when the elastic push plate moves to contact the energy storage baffle, the elastic push plate undergoes elastic deformation under the blocking action of the energy storage baffle; when the elastic push plate continues to move along the second direction and separates from the energy storage baffle, the elastic push plate undergoes elastic reset and ejects the shower gel sample on the conveying device into the collection bin; the second direction is perpendicular to the first direction.

[0012] In one embodiment, the shower gel weighing and rejection machine further includes a fixed base, the fixed base being provided with a limiting boss; the energy storage baffle has a first end and a second end disposed opposite to each other, the first end being rotatably connected to the fixed base, and the second end being disposed between the other side of the elastic push plate and the conveying device;

[0013] When the elastic pusher moves along the second direction under the drive of the rejection drive device, the limiting boss is used to abut against the energy storage baffle to prevent the energy storage baffle from rotating forward under the push of the elastic pusher; when the elastic pusher moves along a third direction under the drive of the rejection drive device, the elastic pusher is used to push the energy storage baffle to rotate in the opposite direction; the third direction is opposite to the second direction.

[0014] In one embodiment, the shower gel weighing and rejection machine further includes an elastic reset member, one end of which is connected to the fixed base, and the other end of which is connected to the energy storage baffle. The elastic reset member is used to drive the energy storage baffle to rotate forward under elastic force and abut against the limiting protrusion.

[0015] In one embodiment, the second end is configured as an arc-shaped structure.

[0016] In one embodiment, the energy storage baffle has a first side and a second side disposed opposite to each other, the first side being disposed facing the conveying device and the second side being disposed away from the conveying device, and the friction coefficient of the first side being less than that of the second side.

[0017] In one embodiment, the shower gel weighing and rejection machine further includes a baffle structure disposed on the side of the collection bin opposite to the conveying device, the baffle structure being used to block the shower gel sample.

[0018] In one embodiment, the material blocking structure has a flexible buffer layer on the side facing the material collection bin.

[0019] In one embodiment, the surface of the elastic push plate is covered with an antistatic layer.

[0020] In one embodiment, the conveying device is configured as a ball conveying module.

[0021] In one embodiment, the rejection drive is configured as a linear cylinder.

[0022] The shower gel weighing and rejection machine provided by this utility model utilizes the blocking effect of an energy-storing baffle on an elastic pusher plate, allowing the pusher plate to continuously accumulate elastic potential energy through its own elastic deformation during movement. When the pusher plate separates from the energy-storing baffle, it quickly and elastically resets, instantly releasing its stored elastic potential energy onto the shower gel sample to be rejected. This generates a significant pushing force on the sample in a very short time, propelling it from the conveying device to the collection bin. This design allows the rejection drive to only need to drive the elastic pusher plate to separate from the energy-storing baffle, eliminating the need for it to move from one side of the conveying device to the other. This shortens the stroke of the rejection drive, reduces the time required to complete one rejection operation, solves the problem of limited conveying speed, and improves overall production efficiency. Furthermore, the increased pushing force makes it more advantageous for rejecting heavier shower gel samples. Attached Figure Description

[0037] Weighing rejection machines are widely used automated equipment in industrial production. They are primarily used to weigh products on the production line and reject those that do not meet weight standards, ensuring product quality stability and consistency. In the production of shower gel, the application of weighing rejection machines is particularly important due to the diversity of product specifications and the stringent quality requirements. Through precise weight detection and rejection mechanisms, shower gel samples that do not meet weight standards can be effectively identified and rejected, thereby ensuring product quality and safety, and improving production efficiency and economic benefits.

[0038] However, existing weighing rejection machines typically use cylinders to directly push out non-conforming samples from the conveyor line, which presents certain problems. Specifically, because the instantaneous pushing force generated by the direct pushing method is limited, to ensure that even heavier samples can be successfully rejected from the conveyor line, the piston of the cylinder needs to move from one side of the conveyor line to the other to ensure that the piston completely pushes the non-conforming sample away from the conveyor line. This necessitates the use of cylinders with longer strokes. The longer stroke naturally increases the time required to complete one rejection operation. Consequently, the conveyor line needs to reduce its conveying speed to accommodate the rejection operation, thus limiting the conveyor line's speed and consequently restricting the improvement of production efficiency.

[0039] To address the aforementioned issues, this invention provides a shower gel weighing and rejection machine, which aims to increase the instantaneous driving force of the drive device during the rejection operation, thereby shortening the stroke of the drive device, reducing the time required to complete one rejection operation, and thus improving overall production efficiency.

[0040] Please see Figures 1 to 3 The shower gel weighing and rejection machine provided by this utility model includes:

[0041] Conveying device 1 is used to convey shower gel samples from weighing area 100 to rejection area 200 along a first direction;

[0042] The rejection drive device 2 is set in the rejection area 200 and located on one side of the conveying device 1;

[0043] Elastic push plate 3, one side of elastic push plate 3 is connected to the rejection drive device 2;

[0044] An energy storage baffle 4 is disposed on the other side of the elastic push plate 3 between the conveying device 1 and the conveying device 1.

[0045] The collection bin 5 is located in the rejection area 200 and on the other side of the conveying device 1;

[0046] The rejection drive device 2 is used to drive the elastic push plate 3 to move along the second direction; when the elastic push plate 3 moves to contact the energy storage baffle 4, the elastic push plate 3 undergoes elastic deformation under the blocking action of the energy storage baffle 4; when the elastic push plate 3 continues to move along the second direction and separates from the energy storage baffle 4, the elastic push plate 3 undergoes elastic reset and ejects the shower gel sample on the conveying device 1 to the collection bin 5; the second direction is perpendicular to the first direction.

[0047] In this embodiment, the conveying device 1 can typically be a conveyor belt, etc., and its function is to sequentially convey the shower gel sample along the first direction to the weighing area 100 and the rejection area 200. When the shower gel sample passes through the weighing area 100, the weighing sensor in the weighing area 100 can detect the weight of the shower gel sample, and the shower gel sample that does not meet the weight standard will be marked as a rejection object.

[0048] The rejection drive device 2 is located on one side of the conveying device 1, and the rejection drive device 2 can be a cylinder or the like. The collection bin 5 is located on the other side of the conveying device 1 and is opposite to the rejection drive device 2. The collection bin 5 is used to collect the rejected shower gel samples for convenient subsequent centralized processing.

[0049] The complete operation process of this embodiment is as follows:

[0050] In the initial state, such as Figure 1 As shown, one side of the elastic push plate 3 is connected to the rejection drive device 2, and the energy storage baffle 4 can be connected to the corresponding frame structure and located between the other side of the elastic push plate 3 and the conveying device 1. The elastic push plate 3 can be made of a material with good elastic deformation capabilities, such as elastic colloid. When the shower gel sample marked as to be rejected enters the rejection area 200 under the drive of the conveying device 1, the rejection drive device 2 will drive the elastic push plate 3 to move along the second direction. When the other side of the elastic push plate 3 contacts the energy storage baffle 4, as... Figure 2 As shown, the elastic pusher 3 will bend due to elastic deformation under the obstruction of the energy storage baffle 4, and will continuously store elastic potential energy during the bending process; under the continuous drive of the removal drive device 2, the elastic pusher 3 moves along the second direction to a preset position, at which point the bending deformation of the elastic pusher 3 reaches its maximum; then the elastic pusher 3 will continue to move along the second direction under the drive of the removal drive device 2 and separate from the energy storage baffle 4, as... Figure 3As shown, at the instant the elastic push plate 3 separates from the energy storage baffle 4, the elastic push plate 3 quickly undergoes elastic reset because it is no longer blocked by the energy storage baffle 4. During the elastic reset process, the elastic push plate 3 will come into contact with the shower gel sample to be rejected. The elastic potential energy stored in the elastic push plate 3 can generate a large pushing force on the shower gel sample. That is, the elastic potential energy stored in the elastic push plate 3 can be converted into the kinetic energy of the shower gel sample in an instant, so that the shower gel sample can be ejected from the conveying device 1 to the collection bin 5 on the other side to complete the rejection operation.

[0051] Therefore, this embodiment utilizes the blocking effect of the energy storage baffle 4 on the elastic push plate 3, allowing the elastic push plate 3 to continuously accumulate elastic potential energy through its own elastic deformation during movement. When the elastic push plate 3 separates from the energy storage baffle 4, the elastic push plate 3 will quickly and elastically reset, instantly releasing its stored elastic potential energy onto the shower gel sample to be rejected. This can generate a large pushing force on the shower gel sample in a very short time, thereby ejecting the shower gel sample from the conveying device 1 to the collection bin 5. This design allows the driving part of the rejection driving device 2 to only drive the elastic push plate 3 to separate from the energy storage baffle 4, without having to move it from one side of the conveying device 1 to the other, thus shortening the stroke of the rejection driving device 2, reducing the time required to complete one rejection operation, solving the problem of limited conveying speed of the conveying device 1, and thus improving overall production efficiency. In addition, due to the increased pushing force, it is more conducive to rejecting heavier shower gel samples.

[0052] In one embodiment, refer to Figures 1 to 3 The shower gel weighing and rejection machine also includes a fixed base 6, which is provided with a limiting boss 61; the energy storage baffle 4 has a first end (not shown in the figure) and a second end (not shown in the figure) that are arranged opposite to each other. The first end is rotatably connected to the fixed base 6, and the second end is arranged between the elastic push plate 3 and the conveying device 1 on the other side.

[0053] When the elastic push plate 3 moves along the second direction under the drive of the rejection drive device 2, the limiting boss 61 is used to abut against the energy storage baffle 4 to prevent the energy storage baffle 4 from rotating forward under the push of the elastic push plate 3; when the elastic push plate 3 moves along the third direction under the drive of the rejection drive device 2, the elastic push plate 3 is used to push the energy storage baffle 4 to rotate in the opposite direction; the third direction is opposite to the second direction.

[0054] by Figures 1 to 3Taking the indicated orientation as an example, forward rotation is counterclockwise rotation, and reverse rotation is clockwise rotation. When the elastic push plate 3 moves along the second direction under the drive of the rejection drive device 2, the limiting boss 61 can prevent the energy storage baffle 4 from rotating forward, so as to ensure that the energy storage baffle 4 can block the elastic push plate 3 moving along the second direction, allowing the elastic push plate 3 to undergo elastic deformation smoothly and complete energy storage. After the corresponding shower gel sample is ejected into the collection bin 5, the rejection drive device 2 needs to drive the elastic push plate 3 to move along the third direction to reset; when the elastic push plate 3 contacts the energy storage baffle 4 during the reset process, the elastic push plate 3 can push the energy storage baffle 4 to rotate in the opposite direction, that is, the energy storage baffle 4 can make way for the elastic push plate 3 by rotating in the opposite direction, without blocking the elastic push plate 3, thereby ensuring that the elastic push plate 3 can be reset to the position under the drive of the rejection drive device 2. Figure 1 The initial position is shown to facilitate the next removal operation.

[0055] Based on the above configuration, the energy storage baffle 4 can block the elastic push plate 3 in one direction, so that the elastic push plate 3 can be reset smoothly after the rejection operation is completed, thereby improving the ease of use.

[0056] In one embodiment, refer to Figures 1 to 3 The shower gel weighing and rejection machine also includes an elastic reset component 7. One end of the elastic reset component 7 is connected to the fixed base 6, and the other end of the elastic reset component 7 is connected to the energy storage baffle 4. The elastic reset component 7 is used to drive the energy storage baffle 4 to rotate in the forward direction under the elastic force and abut against the limiting boss 61.

[0057] In this embodiment, when the elastic push plate 3 contacts the energy storage baffle 4 during the reset process, the energy storage baffle 4 can overcome the elastic force of the elastic reset member 7 and rotate in the opposite direction under the push of the elastic push plate 3 to make way for the elastic push plate 3; when the elastic push plate 3 is reset to the initial position under the drive of the removal drive device 2, the elastic push plate 3 separates from the energy storage baffle 4. At this time, the energy storage baffle 4 can rotate in the forward direction under the elastic force of the elastic reset member 7 and automatically reset to the initial position. Figure 1 The initial position shown allows for direct execution of the next rejection operation.

[0058] This solution simplifies the reset operation of the energy storage baffle 4 by setting up an elastic reset component 7, thereby improving the overall operating efficiency of the equipment.

[0059] In one embodiment, refer to Figures 1 to 3 The second end is designed as an arc-shaped structure.

[0060] By setting the second end of the energy storage baffle 4 that abuts against the elastic push plate 3 to an arc shape, the smoothness of the elastic push plate 3 sliding relative to the second end of the energy storage baffle 4 during the resetting process can be improved, making the elastic push plate 3 push the energy storage baffle 4 more smoothly and avoiding jamming problems. In addition, the arc shape can also disperse stress to a certain extent, avoiding local stress concentration that could cause damage to the energy storage baffle 4.

[0061] In one embodiment, refer to Figures 1 to 3 The energy storage baffle 4 has a first side (not shown in the figure) and a second side (not shown in the figure) arranged opposite to each other. The first side faces the conveying device 1, and the second side faces away from the conveying device 1. The friction coefficient of the first side is less than that of the second side.

[0062] During the removal operation as the elastic pusher 3 moves along the second direction, the elastic pusher 3 contacts the second side of the energy storage baffle 4. By increasing the friction coefficient of the second side, the elastic pusher 3 can be prevented from sliding relative to the second side of the energy storage baffle 4, thus ensuring that the elastic pusher 3 can bend smoothly and complete energy storage under the obstruction of the energy storage baffle 4.

[0063] During the resetting operation of the elastic push plate 3 moving along the third direction, the elastic push plate 3 contacts the first side of the energy storage baffle 4. By reducing the friction coefficient of the first side, it can be ensured that the elastic push plate 3 can be smoothly separated from the energy storage baffle 4 when it is reset to the initial position, so that the energy storage baffle 4 is reset under the elastic force of the elastic reset member 7, thus avoiding the problem of jamming between the elastic push plate 3 and the energy storage baffle 4.

[0064] In one embodiment, refer to Figures 1 to 3 The shower gel weighing and rejection machine also includes a baffle structure 8, which is located on the side of the collection bin 5 facing away from the conveying device 1. The baffle structure 8 is used to block the shower gel samples.

[0065] The main function of the baffle structure 8 is to block the rejected shower gel sample, prevent the shower gel sample from deviating from the collection bin 5 due to excessive speed during the ejection process, and ensure that the shower gel sample can fall smoothly into the collection bin 5.

[0066] In one embodiment, refer to Figures 1 to 3 A flexible buffer layer (not shown in the figure) is provided on the side of the material blocking structure 8 facing the material collection bin 5.

[0067] The flexible buffer layer can be made of materials with cushioning properties such as rubber and sponge. When the rejected shower gel sample collides with the retaining structure 8, the flexible buffer layer can effectively absorb the impact force, reduce damage to the shower gel sample, and reduce the noise generated by the impact.

[0068] In one embodiment, refer to Figures 1 to 3 The surface of the elastic push plate 3 is covered with an anti-static layer (not shown in the figure).

[0069] The antistatic layer can be made of antistatic material and fixed to the surface of the elastic push plate 3 by spraying, pasting, or other methods. During the production process, the antistatic layer can effectively prevent the generation and accumulation of static electricity, avoiding the adsorption between the shower gel sample and the elastic push plate 3 due to the presence of static electricity, which could cause the shower gel sample to fail to eject smoothly or cause ejection deviation, thus ensuring the accuracy and reliability of the rejection operation.

[0070] In one embodiment, refer to Figures 1 to 3 The conveying device 1 is configured as a ball conveying module.

[0071] The ball bearing conveyor module has advantages such as low frictional resistance, smooth operation, and low noise. During the conveying of shower gel samples using the ball bearing conveyor module, when the shower gel sample is pushed by the rejection drive device 2, the sample rolls on the balls of the module in a direction perpendicular to the conveying path. Its friction is lower than the sliding friction of a regular conveyor belt, ensuring that the shower gel sample can move smoothly laterally relative to the conveying device 1 and enter the collection bin 5. This reduces rejection failures caused by jamming between the shower gel sample and the conveying device 1.

[0072] In one embodiment, refer to Figures 1 to 3 The drive unit 2 is replaced with a linear cylinder.

[0073] Linear cylinders offer advantages such as compact structure, fast response speed, and controllable thrust. When driving the elastic pusher 3 to perform the rejection action, the linear cylinder can quickly and accurately provide the required pushing force, ensuring the timeliness and effectiveness of the rejection action.

[0074] It should be noted that other aspects of the shower gel weighing and rejection machine disclosed in this utility model can be found in the prior art, and will not be repeated here.

[0075] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
