Description

Technical Field

[0001] The utility model relates to cocoon processing equipment, in particular to a cocoon picking machine. Background Art

[0002] As sericulture gradually gained popularity, cocoon nets became the most commonly used tool. Specifically, a cocoon net array consists of multiple cells, which are suitable for silkworms to spin silk and spin cocoons in. Part of the silk threads on the outer wall of the cocoon adhere to the inner wall of the cell.

[0003] In some existing designs, workers use tools to push the cocoons out of the cells. This method of picking silkworms / cocoons is relatively inefficient. It is easy for workers to push some cocoons out manually, resulting in cocoon losses and / or hindering the silk reeling process.

[0004] Some designs also use a push-to-pull mechanism to push the cocoons out of the cells. This requires precise positioning fixtures and a constant squareness of the cocoon net to ensure the pushers of the cocoon-picking rollers can accurately pass through the cells and eject the cocoons. This method places high demands on the equipment and fixtures, requiring workers to precisely and precisely attach the cocoon net to the cocoon-picking machine's fixtures, resulting in a minimal improvement in cocoon-picking efficiency. Utility Model Content

[0005] The utility model aims to solve at least one of the above-mentioned technical problems and provides a cocoon picking machine which is easy to operate and has high cocoon picking efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cocoon picking machine comprises a frame, a cocoon picking roller and a cocoon picking impeller.

[0008] The present invention has the advantages that compared with the prior art, the present invention has the following advantages: the cocoons are picked sequentially in the up and down directions, which is convenient for the rapid separation of the cocoons that have left the screen, and the cocoons that have left the screen are prevented from affecting the cocoon picking effect; the double brush rollers pick the cocoons in pairs, and when part of the bristle bundles of one cocoon picking roller are taking the cocoons away, the bristle bundles of the other cocoon picking roller are attached to the cocoons, and part of the bristles of the cocoon picking roller are ready to stick to the cocoons, so that the cocoons on the cocoon picking net can be fully picked by pulling up the cocoon net in a single time, so that the cocoon picking roller can substantially pick the cocoons; the cocoon picking net only needs to be moved up in the cocoon picking gap, and no positioning or orientation is required during the upward movement, and the cocoon picking roller can effectively sweep the cocoons on the cocoon picking net. The present invention has a relatively simple structure, simple operation, and efficient and practical cocoon picking; the impeller is designed to quickly scrape the cocoon picking roller in a pulsed manner, thereby solving the problem of the full effectiveness of the cocoon dropping by the cocoon picking roller and ensuring the cocoon picking quality and efficiency of the cocoon picking machine; when a few cocoons need to be beaten by two blades, the armpits between the blades are also suitable for caching the cocoons to prevent the cocoons from sticking to the brush bundles again.

[0009] As an improvement of the above technical solution, the cocoon picking impeller is used to rotate in the same direction as the corresponding cocoon picking roller.

[0010] As an improvement of the above technical solution, the gap between each pair of cocoon picking rollers is 19-25 mm, and the distance between the free ends of two adjacent brush bundles of the cocoon picking rollers is 19-25 mm.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1 to 3 The present invention provides a cocoon picking machine, including a frame 100, on which a cocoon picking impeller 400 and at least one pair of cocoon picking rollers 200 arranged in sequence from top to bottom are provided. The cocoon picking rollers 200 include a core shaft 210 and a plurality of brush bundles 220 arrayed on the peripheral wall of the core shaft 210. The core shaft 210 is transmission-connected to a cocoon picking motor 300. A cocoon picking gap suitable for pulling up a cocoon breeding net 500 is provided between each pair of cocoon picking rollers 200. The brush bundles 220 of the cocoon picking rollers 200 are suitable for sweeping the cocoon breeding net 500 downwards. The brush bundles 220 are suitable for attaching to and sweeping away the silkworm cocoons 510 on the cocoon breeding net 500. The cocoon picking impeller 400 is transmission-connected to the cocoon picking motor 300 or the cocoon picking motor. The cocoon picking impeller 400 is suitable for removing the silkworm cocoons 510 on the brush bundles 220 at the lower edge of the cocoon picking rollers 200.

[0031] In summary, it can be understood that the cocoon-picking impeller 400 can be driven by the corresponding motor alone, that is, the cocoon-picking impeller 400 is independently connected to the cocoon-picking motor, and the cocoon-picking impeller 400 can also be connected to the same motor as the cocoon-picking roller 200, that is, the cocoon-picking impeller 400 and the cocoon-picking roller 200 are both connected to the cocoon-picking motor 300.

[0032] In the prior art, a stationary baffle interacts with a brush roller. The brush roller has a large number of bristle bundles evenly distributed along its circumference, and the bristles are soft and deformable. Therefore, the interaction between the stationary baffle and the brush roller is relatively stable. The bristles and the cocoons 510 attached to them easily bend and escape the baffle, making it difficult for the brush roller to drop the cocoons, and the brush roller has virtually no cocoon-collecting effect. In the present invention, the cocoons 510 do not have sufficient time to dodge and are struck by the blades 410 of the cocoon-picking impeller 400, causing the cocoons 510 to fully escape from the bristle bundles 220.

[0033] The cocoon picking motor 300 and the cocoon picking motor are electrically connected to a foot switch, and the cocoon picking motor 300 and the cocoon picking motor are connected to a working power supply through the foot switch. The foot switch is suitable for controlling the start and stop of the cocoon picking roller 200 and the cocoon picking impeller 400, so as to reasonably allocate hands and feet in the cocoon picking work.

[0034] Specifically, the cocoon picking motor 300 and the cocoon raking motor are directly connected to the mains power supply via the normally open contacts of an AC contactor / relay. The coil of the AC contactor / relay is connected to a low-voltage DC power source via a foot switch. Preferably, all cocoon picking motors 300 and raking motors are activated by a single foot switch, reducing operator complexity and labor intensity. Furthermore, the raking impeller 400 is drivingly connected to the cocoon picking motor 300 via the cocoon picking roller 200.

[0035] Reference Figure 1 and Figure 2 The cocoon picking motor 300 and the gearbox are a factory-installed whole, which is installed on the base frame 110 or the slide 120 and directly drives the core shaft 210.

[0036] Reference Figure 1 、 Figure 3 and Figure 4 Each pair of cocoon picking rollers 200 is arranged horizontally, or nearly horizontally.

[0037] Reference Figure 1 、 Figure 3 and Figure 4 , the operation process of the utility model can be as follows:

[0038] Start, step on the foot switch to start the at least one pair of cocoon picking rollers 200 and the cocoon picking impeller 400;

[0039] The cocoon net is prepared by feeding the cocoon-raising net 500 from top to bottom into the cocoon-picking gap. Due to the weight of the cocoon-raising net 500, the biting and retraction of the at least one pair of cocoon-picking rollers 200, and / or the pushing of the cocoon-raising net 500 by workers, the leading end / the trailing end of the cocoon-raising net 500 without cocoons is fed in first, until only the trailing end / the leading end of the cocoon-raising net 500 without cocoons remains.

[0040] The cocoon net 500 is pulled upwards to be withdrawn in the reverse direction, and the upwardly moved cocoon net 500 is brushed by the cocoon picking roller 200. The bristle bundle 220 is suitable for adhering to and sweeping the cocoons 510 on the cocoon net 500. Figure 3 , horizontal double brush pairs are used for picking (i.e. each pair of cocoon picking rollers 200 is arranged horizontally or nearly horizontally), and when part of the bristle bundles 220 of the front roller is taken away from the cocoons 510, the part of the bristle bundles 220 of the front roller bends, and the pre-picking cell (i.e. the next cell) of the cocoon breeding net 500 is swung toward the rear roller, and the bristle bundles 220 of the rear roller stick to the cocoons 510. In addition, part of the bristles of the front roller are ready to stick to the cocoons, so the two brush rollers of each pair of cocoon picking rollers 200 have clear division of labor, and a single pull on the cocoon breeding net 500 can fully remove the cocoons 510 on the cocoon breeding net 500, so that the cocoon picking rollers 200 can substantially produce a cocoon picking effect.

[0041] When the cocoon-raising net 500 is pulled too fast and some cells are not fully cocooned, the uncocooned area is fed again and the net is withdrawn to collect cocoons again.

[0042] In some designs, the cocoon picking roller 200 and the cocoon picking impeller 400 rotate at approximately 150 rpm. The actual diameter of the cocoon picking roller 200 is approximately 130 mm. This means the actual linear velocity of the cocoon picking roller 200 (i.e., the linear velocity of the free end of the bristle bundle 220) is approximately 325π mm / s, or 1021 mm / s. The pulling speed of the cocoon net 500 is required to be less than approximately 80 mm / s. If the cocoon net 500 is pulled up too quickly, workers can adjust it themselves.

[0043] In some designs of the present invention, the cocoon picking machine is fully mechanized, employing tools such as claws or calipers to pull the new cocoon net 500 directly from bottom to top through the cocoon picking gap. The upper end of the cocoon picking machine uses a clamp to pull the cocoon net 500. In other words, this design eliminates the aforementioned "net preparation" step. In some embodiments, the cocoon picking machine is equipped with at least two cocoon picking stations, each equipped with at least one pair of cocoon picking rollers 200 arranged in sequence from top to bottom. While some cocoon picking stations are harvesting cocoons, others can be replenished with new cocoon net 500 from bottom to top.

[0044] Compared with the prior art, the present invention has the following beneficial effects: cocoons are picked sequentially in the up-down direction, which facilitates the rapid separation of the cocoons 510 that have left the mesh, thereby preventing the cocoons 510 that have left the mesh from affecting the cocoon picking effect; the double brush rollers pick the cocoons in pairs, and when part of the bristle bundles 220 of one cocoon picking roller 200 is taken away from the cocoons 510, the bristle bundles 220 of the other cocoon picking roller 200 adhere to the cocoons 510, and part of the bristles of the cocoon picking roller 200 are ready to stick to the cocoons, so that the cocoons 510 on the cocoon raising net 500 can be fully picked by pulling the cocoon raising net 500 once, so that the cocoon picking roller 200 can substantially pick the cocoons; The cocoon-raising net 500 only needs to be moved up in the cocoon-picking gap, and no positioning or orientation is required during the upward movement. The cocoon-picking roller 200 can effectively sweep the cocoons 510 on the cocoon-raising net 500. The structure of the utility model is relatively simple, the operation is simple, and the cocoon-picking is efficient and practical. The impeller is designed to quickly scrape the cocoon-picking roller 200 in a pulsed manner, thereby solving the problem of the cocoon-dropping roller 200 being fully effective and ensuring the cocoon-picking quality and efficiency of the cocoon-picking machine. When a few cocoons 510 need to be beaten by two blades 410, the armpits between the blades 410 are also suitable for caching the cocoons 510 to prevent the cocoons 510 from sticking to the brush bundle 220 again.

[0045] Reference Figure 1 、 Figure 3 Preferably, the cocoon picking impeller 400 deviates from the corresponding cocoon picking gap relative to its corresponding cocoon picking roller 200, and the cocoon breeding net 500 deviates from the cocoon picking impeller 400 when feeding the cocoon picking gap and performing cocoon picking and dropping. Figure 1 and Figure 3The cocoon picking machine is preferably provided with a pair of cocoon picking rollers 200 and a pair of cocoon picking impellers 400. After the cocoon picking rollers 200 and the corresponding cocoon picking impellers 400 are chain-driven, the two chains form an upright figure eight shape.

[0046] Reference Figure 3 In some embodiments of the present invention, the cocoon-picking impeller 400 is adapted to rotate in the same direction as the corresponding cocoon-picking roller 200, that is, the cocoon-picking impeller 400 and the corresponding cocoon-picking roller 200 both rotate clockwise or counterclockwise. Therefore, in the area where the cocoon-picking impeller 400 and the cocoon-picking roller 200 are scraping each other, the linear speeds of the cocoon-picking impeller 400 and the cocoon-picking roller 200 are in opposite directions, and the cocoon-picking impeller 400 has a stronger efficiency in removing the cocoons 510. Figure 3 In addition, the cocoon picking impeller 400 and its corresponding cocoon picking roller 200 have the same rotation direction, that is, Figure 3 Shown W 11 With W 12 Same direction, W 21 With W 22 The same direction is adopted, and because the bristle bundles 220 of each pair of cocoon picking rollers 200 are used to sweep the cocoon breeding net 500 downwards, the adjacent sides of each pair of cocoon picking impellers 400 are all prying downwards, which is beneficial for accelerating the falling of the silk cocoons 510 and also makes the silk cocoons 510 picked by each pair of cocoon picking rollers 200 fall back in the center, preventing the silk cocoons 510 from splashing and scattering outwards.

[0047] Optimally designed, reference Figure 1 、 Figure 3 , the cocoon picking roller 200 and the cocoon picking impeller 400 are provided with sprockets, and the cocoon picking roller 200 and its corresponding cocoon picking impeller 400 are chain driven. The cocoon picking roller 200 and its corresponding cocoon picking impeller 400 can also be driven by an odd number of gears.

[0048] Reference Figure 1 、 Figure 3 In some embodiments of the present invention, the cocoon picking impeller 400 is evenly distributed with 6-10 blades 410, preferably 8 blades 410, to avoid excessive beating of the cocoons 510, thereby protecting the cocoons 510 and avoiding motor overload. The cocoon picking roller 200 has a better cocoon dropping effect.

[0049] The diameter of the cocoon 510 is generally 17-21 mm. The surface is fluffy and has a small amount of silk. Some of this silk adheres to the inner wall of the cell of the cocoon net 500, so that the cocoon 510 is bound to the cell. The diameter of the cocoon 510 is most commonly 19-20 mm. The length and width of the cell of the cocoon net 500 are both greater than 25 mm. The cocoon net 500 is about 3 m long and 1 m wide. Figure 4As shown, the length or width of the cell is L, the diameter of the cocoon 510 including the fluffy surface is D, which is generally 19-27 mm, and the gap d between each pair of cocoon picking rollers 200 is the cocoon picking gap d.

[0050] In some embodiments of the present invention, the gaps d, d between each pair of cocoon picking rollers 200 are 19-25 mm, preferably 21-23 mm. The bristle bundles 220 effectively adhere to the cocoons 510, and the cocoons 510 on the bristle bundles 220 are easily removed by the cocoon picking impeller 400.

[0051] Reference Figure 1 、 Figure 2 In some embodiments of the present invention, the frame 100 includes a basic frame 110 and a slide 120 slidably connected to the basic frame 110. The basic frame 110 is provided with corresponding guide rails, guide rods or guide grooves, etc. In each pair of cocoon picking rollers 200, one cocoon picking roller 200 and its corresponding cocoon picking impeller 400 are both mounted on the basic frame 110 at both ends, and the other cocoon picking roller 200 and its corresponding cocoon picking impeller 400 are both mounted on the corresponding slide 120 at both ends. The slide 120 is connected to the basic frame 110 by an adjusting screw 130, and the adjusting screw 130 is suitable for adjusting the cocoon picking gap.

[0052] Reference Figure 1 、 Figure 2 The basic frame 110 includes a frame, a back plate and side plates detachably connected to the frame, and combined with the guide inclined plate 160, the basic frame 110 defines a chamber suitable for collecting impurities.

[0053] Regarding the adjustment structure of the adjusting screw 130, it can be understood that the adjusting screw 130 is integrally formed with a raised ring. One of the base frame 110 and the slide 120 limits the movement of the raised ring and is rotationally connected to the raised ring, while the other is threadedly connected to the adjusting screw 130. In other words, one of the base frame 110 and the slide 120 is axially fixed relative to the adjusting screw, while the other acts as a nut that rotates relative to the screw / threaded rod.

[0054] Preferably, the basic frame 110 is provided with a scale, which is suitable for manually reading the variation of the cocoon picking gap.

[0055] Reference Figure 1 and Figure 2 Both ends of the cocoon picking roller 200 and the cocoon picking impeller 400 are installed through rolling bearings, and the frame 100 is provided with a bearing cover 170 suitable for encapsulating the rolling bearings.

[0056] The cocoon picking roller 200 and the cocoon picking impeller 400 are both large in the middle and small at both ends, and the problem of disassembly and assembly of the cocoon picking roller 200 and the cocoon picking impeller 400 is not solved. Figure 1 、 Figure 2Preferably, the basic frame 110 is detachably connected to a fixed mounting plate, and the non-adjustable cocoon picking roller 200 and the cocoon picking impeller 400 are both mounted on the fixed mounting plate at least at one end, and at least one slide 120 includes a slider and a movable mounting plate detachably connected to the slider, and the adjustable cocoon picking roller 200 and the cocoon picking impeller 400 are both mounted on the movable mounting plate at least at one end.

[0057] In some embodiments of the present invention, a terminal block is embedded on the outer side of the frame 100, the inner side of the terminal block is suitable for electrically connecting to the corresponding cocoon picking motor 300, and the outer side of the terminal block is suitable for plugging in a power cord. The cocoon picking machine is miniaturized and easy to move, and can be used by directly connecting to the power supply after installation.

[0058] The bottom of the frame 100 is provided with ground rollers to solve the problem of the convenience of moving the cocoon picking machine, and the cocoon picking machine can conveniently move in various lanes of the silkworm breeding workshop.

[0059] Reference Figure 1 、 Figure 3 In some embodiments of the present invention, a guide inclined plate 160 is provided below the cocoon-picking impeller 400. The guide inclined plate 160 is suitable for guiding the falling cocoons 510 to deviate from the cocoon-picking impeller 400, so that the collected cocoons 510 are collected into a collecting trough or a relatively open ground, thereby preventing the collected cocoons 510 from piling up to the cocoon-picking impeller 400.

[0060] Reference Figure 1 、 Figure 3 In some embodiments of the present invention, the guide plate 160 is a mesh plate adapted to filter out impurities swept from the cocoon-raising net 500. Specifically, while spinning silk on the cocoon-raising net 500, silkworms excrete feces, with some feces particles / lumps remaining in the cells. When the cocoon-raising net 500 shakes and / or the cocoons 510 detach from the cells, these feces particles detach from the cells and also fall downward.

[0061] In some embodiments of the present invention, the diameter of each bristle in the bristle bundle 220 is 0.35-0.6 mm, and the portion of each bristle protruding from the core shaft 210 is 20-30 mm long. The bristle bundle 220 is made of nylon, polyester, graphene, microfiber, plant fiber, or rubber. The plant fiber can be palm, bamboo, straw, or hemp. Preferably, the diameter of each bristle is 0.4-0.5 mm, and the portion of each bristle protruding from the core shaft 210 is 22-25 mm long.

[0062] Reference Figure 1 、 Figure 3In some embodiments of the present invention, a traction wheel 140 is further included. The traction wheel 140 is suitable for winding the cocoon-raising net 500 that has passed through the cocoon picking gap. The traction wheel 140 is suitable as a fulcrum when the cocoon-raising net 500 is pulled up, so that the cocoon-raising net 500 is pulled upward along the normal axis of each pair of cocoon picking rollers 200, thereby reducing the labor intensity of workers lifting the cocoon-raising net 500.

[0063] Reference Figure 1 、 Figure 3 In some embodiments of the present invention, an operating platform 150 is further included. The operating platform 150 is suitable for sliding the cocoon-breeding net 500 that has passed through the traction wheel 140, for stopping the cocoon-breeding net 500, and / or for releasing the cocoon-breeding net 500 to fall.

[0064] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the present invention. Any modification or equivalent replacement that does not depart from the spirit and scope of the present invention shall be included in the scope of the technical solution of the present invention.
