Description

Technical Field

[0001] The utility model relates to the technical field of fresh fruit packaging equipment, in particular to a bag-supporting device used for fresh fruit net bag packaging. Background Art

[0002] The loss of fresh fruits mainly occurs in the process of picking, packaging, and transportation. Among them, the transportation process is the main cause of fresh fruit loss. As a result, how to reduce the loss of fresh fruits in the transportation process has become a problem that the fruit industry needs to solve urgently. For example, after fresh fruits such as prunes or apricots are sorted, plastic foam nets are usually used to wrap the fruit bodies in order to reduce losses during transportation. The use of plastic foam nets to package fresh fruits can greatly improve the quality and appearance of fresh fruits, reduce the loss rate in the transportation process, and enhance the commodity and market competitiveness of fruits.

[0003] In order to improve the efficiency of bagging, those skilled in the art have developed some semi-automatic fresh fruit packaging equipment or auxiliary tools. For example, Chinese patent document CN108639423A discloses an automatic net-wrapping packaging machine for round fruits. The automatic net-wrapping packaging machine uses a net-wrapping mechanism to realize net-wrapping conveyance and net-wrapping movement, and a net-supporting cylinder for supporting the net-wrapping is arranged on the net-supporting frame, so as to facilitate the entry of fruits into the net-wrapping.

[0004] However, when the net-supporting cylinder is used to stretch the opening of the net bag, the opening is easily stretched too much, causing the net bag to lose its elasticity, and further making it difficult for the opening of the net bag to return to its contracted state after the fresh fruit is packaged. As a result, the fresh fruit is still easy to fall off from the opening of the net bag during transportation, affecting the protective effect of the net bag. Summary of the invention

[0005] The purpose of the utility model is to provide a bag-supporting device for supporting the bag opening of the foaming net bag during the process of packaging fresh fruits in the foaming net bag, so as to facilitate the smooth entry of the fresh fruits into the foaming net bag, and at the same time, avoid over-stretching the bag opening of the foaming net bag and maintain the elasticity of the foaming net bag.

[0006] In order to achieve the above purpose, the utility model adopts the following scheme:

The cylinder body of the parallel-type clamping cylinder is installed on the connecting frame. The clamp of the parallel-type clamping cylinder is located in the channel. A pair of clamps are opened in the channel to expand the bag opening of the foaming mesh bag. The limiting plate is arranged parallel to the clamp and is located on the outside of the pair of clamps.

[0009] Preferably, the telescopic assembly includes a power cylinder, a guide rail, a slide and a mounting plate. The guide rail is arranged parallel to the power cylinder, the slide is embedded in the guide rail, one end of the mounting plate is connected to the slide, the other end of the mounting plate is connected to the connecting part of the connecting frame, and the piston rod of the power cylinder is connected to the mounting plate.

[0010] Preferably, the bag-stretching assembly has a first position and a second position in the axial direction of the foaming mesh bag, and the telescopic assembly is used to drive the bag-stretching assembly back and forth between the first position and the second position, the first position is located at the bag opening of the foaming mesh bag, and the second position is located below the first position.

[0011] Preferably, a guide cover is provided on the connecting frame, and the guide cover is located below the channel.

DETAILED DESCRIPTION

[0025] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-7 As shown, in the embodiment of the utility model, a bag-supporting device for fresh fruit mesh bag packaging is proposed, which is intended to support the bag opening of the foaming mesh bag to facilitate the smooth entry of the fresh fruit into the foaming mesh bag, while avoiding excessive stretching of the bag opening of the foaming mesh bag to maintain the elasticity of the foaming mesh bag.

[0027] The bag-supporting device for fresh fruit net bag packaging proposed in the embodiment of the utility model limits the opening range of a pair of clamps of the parallel clamping claw cylinder through a limit plate, thereby preventing the bag opening of the foaming net bag from being overstretched, maintaining the elasticity of the bag opening of the foaming net bag, and effectively preventing the fresh fruit from escaping from the bag opening of the foaming net bag, thereby ensuring the protective effect of the foaming net bag on the fresh fruit. At the same time, the opened clamps and the limit plate clamp the bag opening of the foaming net bag, and under the drive of the telescopic component, it is convenient to form axial traction on the foaming net bag, which is further conducive to the smooth entry of the fresh fruit into the foaming net bag.

[0028] like Figure 1 As shown, Figure 1 As shown, a fresh fruit net bag packaging machine includes a conveying unit 1, a lifting component 2, a net bag clamping unit 3, a bag supporting device 4 and a cutting component 5.

[0029] like Figure 1 Combination Figure 2 As shown, the conveying unit 1 is used to convey fresh fruits. The conveying unit 1 defines a conveying plane 6. The fresh fruits are arranged in a straight line in the conveying plane 6 along the conveying direction of the conveying unit 1. A placement cavity 7 for supporting the fresh fruits is provided on the conveying plane 6. Figure 3 As shown, a mounting station 8 is arranged above the conveying plane 6 .

[0030] For example, the conveying unit 1 uses a conveyor chain device. The conveyor chain device is provided with a roller assembly for supporting fresh fruits. The conveyor chain device drives the roller assembly to rotate, and continuously transports the fresh fruits in the loading area to the bottom of the set station 8. A placement cavity 7 for supporting fresh fruits is formed between adjacent roller assemblies.

[0031] like Figure 1 As shown, the lifting component 2 is used to lift the fresh fruit in the placement cavity 7 out of the conveying plane 6. The lifting component 2 defines a lifting direction. For example, the conveying unit 1 conveys the fresh fruit in a horizontal plane, and the lifting direction of the lifting component 2 is arranged perpendicular to the horizontal plane. The lifting direction can also be appropriately adjusted according to the angle formed by the conveying plane 6 and the horizontal plane, so as to smoothly lift the fresh fruit out of the conveying plane 6 and prevent the fresh fruit from falling when the fresh fruit enters the set station 8.

[0032] like Figure 2 Combination Figure 5 As shown, the lifting assembly 2 is located below the conveying unit 1. The lifting assembly 2 includes a support frame 21, a lifting cylinder 22, and a tray 23 for passing through the placement cavity 7 to lift the fresh fruit. The lifting cylinder 22 is arranged perpendicular to the conveying plane 6. The cylinder body of the lifting cylinder 22 is installed on the support frame 21. The piston rod of the lifting cylinder 22 is connected to the tray 23. Figure 6 The direction indicated by the dotted arrow shown in is the lifting direction of the lifting assembly 2.

[0033] When the lifting assembly 2 is in use, it cooperates with the conveying unit 1. When the conveying unit 1 conveys the fresh fruit to the bottom of the packaging station 8, the conveying unit 1 stops conveying, and the lifting cylinder 22 is actuated to drive the tray 23 to rise, lift the fresh fruit in the placement cavity 7 out of the conveying plane 6, and deliver the fresh fruit to the packaging station 8. After the fresh fruit is packaged in the packaging station 8, the lifting cylinder 22 is actuated to drive the tray 23 to retract to the bottom of the conveying plane 6, and the conveying unit 1 continues to start and deliver the next fresh fruit to the bottom of the packaging station 8.

[0034] like Figure 2 As shown, the net bag clamping and conveying unit 3 is used to convey the foaming net bag to the suiting station 8, and make the bag mouth of the foaming net bag face the conveying plane 6. For example, the net bag clamping and conveying unit 3 is located above the suiting station 8. The net bag clamping and conveying unit 3 includes a storage rack 31 for storing the foaming net bag, and a feeding channel 415 is formed between the storage rack 31 and the suiting station 8. The feeding channel 415 is provided with a first clamping plate assembly 32, a second clamping plate assembly 33 and a clamping and conveying roller assembly 34. The clamping and conveying roller assembly 34 is located between the first clamping plate assembly 32 and the second clamping plate assembly. The clamping and conveying roller assembly 34 is used to form a conveying traction for the foaming net bag. The first clamping plate assembly 32 is located between the storage rack 31 and the clamping and conveying roller assembly 34.

[0035] like Figure 4 As shown, during the process of the net bag clamping and conveying unit 3 conveying the foaming net bag, the first clamping plate assembly 32 and the second clamping plate assembly 33 both play the role of clamping or releasing the foaming net bag. When the net bag clamping and conveying unit 3 is in use, the second clamping plate assembly 33 clamps the foaming net bag, the first clamping plate assembly 32 releases the foaming net bag, and the clamping roller assembly 34 rotates to drive the foaming net bag to move in the direction of the second clamping plate assembly 33. Some of the foaming net bags in the storage rack 31 are conveyed out, and the foaming net bags are compressed between the second clamping plate assembly 33 and the clamping roller assembly 34. The length of the compressed foaming net bag is sufficient for packaging a single fresh fruit. Subsequently, the first clamping plate assembly 32 clamps the foaming net bag, and the second clamping plate assembly 33 releases the foaming net bag, so that the bag mouth of the foaming net bag faces the set station 8, which is convenient for the subsequent bag-supporting and set operation.

[0036] like Figure 1 As shown, the cutting assembly 5 is located between the set station 8 and the mesh bag clamping and conveying unit 3. The cutting assembly 5 is used to cut the foaming mesh bag.

[0037] like Figure 7 As shown, the cutting assembly 5 includes a frame 51, a cutting wire 52 for electrically heating, and a cutting cylinder 53. The cutting cylinder 53 is arranged perpendicular to the lifting direction. The cutting cylinder 53 is used to drive the frame 51 to reciprocate along the radial direction of the foaming mesh bag. The frame 51 is connected to the piston rod of the cutting cylinder 53. The cutting wire 52 is installed on the frame 51.

[0038] In order to facilitate the packaged fresh fruits to leave the packaging station 8, a fruit pushing assembly for pushing the packaged fresh fruits out of the packaging station 8 is provided on the inner side of the frame 51. The fruit pushing assembly includes a push plate 54 and a fruit pushing cylinder. The fruit pushing cylinder is arranged parallel to the cutting cylinder 53. The cylinder body of the fruit pushing cylinder is installed on the frame 51. The push plate 54 is connected to the piston rod of the fruit pushing cylinder. For example, after the fresh fruits are packaged, a collection step is also included. In the collection step, the fruit pushing assembly pushes the packaged fresh fruits to a collection box located on one side of the conveying unit 1.

[0039] The push plate has a straight plate section and an arc plate section connected in sequence. The straight plate section is installed on the piston rod of the fruit pushing cylinder. The arc plate section plays a certain protective effect when pushing out the packaged fresh fruit, which is conducive to decomposing the thrust into horizontal force and vertical force. For example, the arc plate section of the push plate can also be provided with an arc groove for matching the fresh fruit. The arc groove is used to further fit the outer contour of the packaged fresh fruit.

[0040] like Figure 4 As shown, the bag-holding device 4 includes a bag-holding assembly 41 for holding up the bag opening of the foaming net bag, and a telescopic assembly 42 for driving the bag-holding assembly 41 to reciprocate along the lifting direction. The bag-holding assembly 41 has a first position and a second position in the lifting direction. The telescopic assembly 42 is used to drive the bag-holding assembly 41 to reciprocate between the first position and the second position.

[0041] The first position is located at the discharge port of the net bag clamping and conveying unit 3, and the second position is located between the set station 8 and the conveying plane 6. In the first position, the bag support component 41 supports the bag opening of the foaming net bag; when the telescopic component 42 drives the bag support component 41 to move from the first position to the second position, the foaming net bag is pulled and stretched into the set station 8, and the lifting component 2 lifts the fresh fruit out of the conveying plane 6 and delivers the fresh fruit into the foaming net bag; in the second position, the cutting component 5 cuts the foaming net bag along the radial direction of the foaming net bag.

[0042] like Figure 6 As shown, the bag support assembly 41 includes a connecting frame 411, a parallel clamping cylinder 412 and a limit plate 414. The connecting frame 411 is provided with a connecting portion for connecting the telescopic assembly 42. A channel 415 for fresh fruit to pass through is provided on one side of the connecting frame 411. The cylinder body of the parallel clamping cylinder 412 is installed on the connecting frame 411. The clamp 413 of the parallel clamping cylinder 412 is located in the channel 415, and a pair of clamps 413 are opened in the channel 415 to expand the bag mouth of the foaming net bag. The limit plate 414 is arranged parallel to the clamp 413 and is located on the outside of the pair of clamps 413.

[0043] For example, the limiting plate 414 is an L-shaped plate, so that the limiting plate 414 can be easily installed on the connecting frame 411.

[0044] like Figure 4 Combination Figure 6 As shown, the telescopic assembly 42 includes a power cylinder 421, a guide rail 422, a slide 423 and a mounting plate 424. The axis of the power cylinder 421 is arranged parallel to the lifting direction. The guide rail 422 is arranged parallel to the power cylinder 421. The slide 423 is embedded in the guide rail 422. One end of the mounting plate 424 is connected to the slide 423, and the other end of the mounting plate 424 is connected to the connecting portion of the connecting frame 411. The piston rod of the power cylinder 421 is connected to the mounting plate 424.

[0045] For example, the mounting plate 424 is connected to the connecting portion of the connecting frame 411 through a fastener. The power cylinder 421 is arranged parallel to the axial direction of the foaming mesh bag.

[0046] like Figure 6 As shown, a guide cover 416 is provided on the connecting frame 411. The guide cover 416 is located below the channel 415. The guide cover 416 is used to guide the fresh fruit to prevent the fresh fruit from rolling off the tray during the lifting process. For example, the guide cover 416 is in a trumpet shape. The guide cover 416 can be selected in a size structure according to the type of fresh fruit to better cover the fresh fruit.

[0047] When the bag-supporting device for fresh fruit net bag packaging proposed in the embodiment of the utility model is used, the limit plate 414 limits the opening range of a pair of clamps of the parallel clamping claw cylinder 412, thereby preventing the bag opening of the foaming net bag from being overstretched, maintaining the elasticity of the bag opening of the foaming net bag, and effectively preventing the fresh fruit from escaping from the bag opening of the foaming net bag, thereby ensuring the protective effect of the foaming net bag on the fresh fruit. At the same time, the opened clamps and the limit plate 414 clamp the bag opening of the foaming net bag, and under the drive of the telescopic component 42, it is convenient to form axial traction on the foaming net bag, which is further conducive to the smooth entry of the fresh fruit into the foaming net bag.

[0048] The present invention is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present invention may also have other implementation modes. For those skilled in the art, any technical solutions formed by any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
