Description

Technical Field

[0001] The invention belongs to the technical field of gas cleaning, and in particular relates to food mold cleaning equipment. Background Art

[0002] In the food processing industry, food molds are widely used to shape foods such as biscuits, chocolate, and pastries. These molds often have grooves to form specific food shapes. After the food is demolded, debris and other residues may remain in the grooves. Failure to thoroughly clean these residues can affect the quality and hygiene of subsequent food production.

[0003] Currently, the industry generally uses an air jet method to clean residue from the grooves of food molds. Specifically, the food mold is placed on a conveyor, which transports the food mold from left to right. The air jet is then applied to the grooves of the food mold to eject the residue from the grooves and separate it from the food mold. For example, patent publication number CN208787092U discloses a fume purification device for baking trays that uses this method to clean baking trays.

[0004] In the prior art, the jet device usually jets toward the lower left instead of vertically downward. The reason is that if the jet device jets vertically downward, the airflow may press the residue vertically to the bottom of the groove, making it difficult to blow it away; when the jet is jetted toward the lower left, the airflow will produce lateral separation, which can ensure that the blown residue is separated from the food mold, and can prevent the blown residue from being blown back into the downstream food mold due to the continuous rightward movement of the food mold, causing cross contamination.

[0005] Although the jet device can improve the cleaning effect by spraying air toward the lower left, there are some problems in actual use: the groove has a certain depth, and the jet device sprays air from the top of the food mold toward the lower left. Due to the obstruction of the food mold, the right part of the groove cannot be covered by the airflow, and there is a dead corner for cleaning. As a result, the residue in this part cannot be blown away from the food mold, affecting the quality and hygiene of subsequent food production, and the cleaning effect is poor. Summary of the Invention

[0006] The present invention provides a food mold cleaning device to solve the technical problem in the prior art that there are cleaning dead corners resulting in poor cleaning effect.

[0007] To solve the above-mentioned problems, the present invention provides a food mold cleaning device adopting the following technical solution: a food mold cleaning device comprising a frame, a conveying device and an air jet device provided on the frame, wherein the conveying device conveys the food mold from left to right; the air jet device comprises a base provided on the frame, a first air jet block rotatably mounted on the base, a second air jet block rotatably mounted on the bottom of the first air jet block, a first elastic member, a second elastic member, and a pushing mechanism, wherein the rotation axes of the first and second air jet blocks extend forward and backward; the first air jet block is provided with a first air jet port for jetting air toward the lower left, and the bottom of the second air jet block is provided with a second air jet port, and the first elastic member drives the first air jet block toward the left;

[0008] The pushing mechanism includes a sliding rod slidably assembled at the bottom of the first jet block in the left-right direction, and also includes a gear transmission structure connecting the sliding rod and the second jet block. The second elastic member is provided on the first jet block and pushes the sliding rod toward the left. The sliding rod has a force-bearing portion protruding toward the left. When the sliding rod moves to the right, the gear transmission structure drives the second jet block to swing to the right. After the second elastic member is compressed, the first jet block is driven to swing to the right. When the sliding rod moves to the left, the second jet block is driven to swing to the left.

[0009] The first jet block has a cleaning state. When in the cleaning state, the bottom of the second jet block and the force-bearing part of the sliding rod are both located in the groove of the food mold. When the food mold moves to the right, the left groove wall pushes the force-bearing part, thereby driving the sliding rod to move to the right in turn, and the second jet block and the first jet block swing to the right, and drive the second jet block and the sliding rod to swing out of the groove.

[0010] When the first jet block is in the cleaning state, the bottom of the second jet block is located in the groove, and gas is ejected toward the lower left through the first jet port, jet-cleaning the bottom and left side of the groove. As the food mold moves to the left, the left side wall of the groove pushes the force-bearing portion toward the right, causing the sliding rod to move to the right. After the sliding rod moves to the right, the gear transmission structure drives the second jet block to swing to the right. As the second jet block swings, the second jet port jet-cleans the right side of the groove, avoiding blind spots and improving the cleaning effect. As the sliding rod moves to the right, it compresses the second elastic member. When the second elastic member is compressed to a set degree, the thrust transmitted by the second elastic member can drive the first jet block to swing to the right. After the first jet block swings to the right, it can drive the second jet block and the sliding rod to swing to the right. As the food mold continues to move to the right, the second jet block and the sliding rod swing to the right with greater amplitude, allowing them to completely swing out of the groove and avoid the food mold. When the next groove is to be cleaned, the force-bearing part is separated from the food mold, the first elastic member drives the first jet block to swing to the cleaning state, and the second elastic member also drives the sliding rod to slide to the left to reset, and the next cleaning process begins again.

[0011] As a further improvement, the gear transmission structure includes a first transmission tooth segment arranged at the bottom of the sliding rod, an intermediate gear rotatably mounted on the first jet block, and a second transmission tooth segment arranged on the second jet block. The first transmission tooth segment and the second transmission tooth segment are respectively engaged with the top and bottom sides of the intermediate gear.

[0012] As a further improvement, the second elastic member is a compression spring;

[0013] The pushing mechanism also includes a guide rod fixed on the first jet block and extending left and right. The right end of the sliding rod is slidably sleeved on the outside of the guide rod. The compression spring is sleeved on the guide rod and pushes the sliding rod toward the left.

[0014] As a further improvement, the pushing mechanism further includes an adjusting nut threadedly assembled on the guide rod, and the compression spring is elastically pressed between the adjusting nut and the sliding rod.

[0015] The adjustment nut changes the initial compression of the compression spring, thereby adjusting its firmness. For smaller grooves, the compression spring is adjusted to a harder setting to allow the second jet block and sliding rod to quickly swing out of the groove, quickly transferring the thrust to the first jet block. For larger grooves, the compression spring is adjusted to a softer setting to prolong the time the second jet block and sliding rod remain in the groove, improving the jet cleaning effect on the right side of the groove.

[0016] As a further improvement, the force-bearing portion of the sliding rod is bent downward and then extended to the left.

[0017] As a further improvement, the first air jet opening and the second air jet opening are both long openings extending along the front-to-back extension direction.

[0018] The first air jet opening and the second air jet opening are both long openings, which can increase the area covered by the air flow and enhance the effect of the air jet cleaning.

[0019] As a further improvement, the base cover is arranged outside the first jet block and the second jet block;

[0020] An exhaust channel is provided in the base, and exhaust ports are provided at the bottom of the exhaust channel on the left and right sides of the first and second jet blocks. An exhaust pipe is connected to the base, and the exhaust pipe is communicated with the exhaust channel.

[0021] The base is equipped with an air extraction channel to suck out the residue blown out of the groove, preventing the residue from falling back into the groove and causing secondary contamination. In addition, the front and back sides of the base are equipped with air extraction ports to enhance the suction effect.

[0022] As a further improvement, the base includes a fixing plate fixed to the frame, a fixing box provided on the fixing plate, and a U-shaped plate provided inside the fixing box, the fixing box including a first top plate, two first side plates, and two closing plates, the two first side plates are arranged at intervals on the left and right and fixed to the bottom of the first top plate, and the two closing plates are fixed to the front and rear sides of the first top plate and the first side plate; the U-shaped plate includes a second top plate and two second side plates, the second top plate and the second side plates are both fixed to the closing plates, the second top plate is located below the first top plate in a spaced-apart manner, and the second side plate is located on one side of the first side plate in a spaced-apart manner;

[0023] The space between the first top plate and the second top plate and the space between the first side plate and the second side plate together form the air extraction channel.

[0024] As a further improvement, the fixing box is assembled on the fixing plate in an adjustable manner along the up and down directions.

[0025] When the fixing box is adjusted up and down, the first jet block and the second jet block can be driven to adjust up and down, and can adapt to food molds of different thicknesses.

[0026] As a further improvement, the base includes a fixed shaft located at the bottom, the first jet block is rotatably mounted on the fixed shaft, and the first elastic member is a torsion spring provided between the fixed shaft and the first jet block.

[0027] The beneficial effects are:

[0028] 1. When the first jet block is in the cleaning state, the bottom of the second jet block is located in the groove, and gas is ejected toward the lower left through the first jet port, jet cleaning the bottom and left side of the groove. As the food mold moves to the left, the left side wall of the groove pushes the force-bearing portion toward the right, causing the sliding rod to move to the right. After the sliding rod moves to the right, the gear transmission structure drives the second jet block to swing to the right. As the second jet block swings, the second jet port jet cleans the right side of the groove, avoiding blind spots and improving the cleaning effect. As the sliding rod moves to the right, it compresses the second elastic member. When the second elastic member is compressed to a set degree, the thrust transmitted by the second elastic member can drive the first jet block to swing to the right. After the first jet block swings to the right, it can drive the second jet block and the sliding rod to swing to the right. As the food mold continues to move to the right, the second jet block and the sliding rod swing to the right more and more, completely swinging out of the groove to avoid the food mold. When the next groove is to be cleaned, the force-bearing part is separated from the food mold, the first elastic member drives the first jet block to swing to the cleaning state, and the second elastic member also drives the sliding rod to slide to the left to reset, and the next cleaning process begins again.

[0029] 2. The adjustment nut changes the initial compression of the compression spring, thereby adjusting its firmness. For smaller grooves, adjust the compression spring to a harder setting to allow the second jet block and sliding rod to quickly swing out of the groove, quickly transferring the thrust to the first jet block. For larger grooves, adjust the compression spring to a softer setting to extend the time the second jet block and sliding rod remain in the groove, improving the jet cleaning effect on the right side of the groove.

[0030] 3. The first jet port and the second jet port are both long, which can increase the area covered by the airflow and enhance the effect of jet cleaning.

[0031] 4. The base is equipped with an air extraction channel to extract the residues blown out of the groove, preventing the residues from falling back into the groove and causing secondary contamination. In addition, there are air extraction ports on both the front and back sides of the base to enhance the suction effect.

[0032] 5. When the fixed box is adjusted up and down, it can drive the first jet block and the second jet block to adjust up and down, which can adapt to food molds of different thicknesses. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The food mold cleaning device comprises a frame 1, a conveying device, and an air-jet device, wherein the conveying device and the air-jet device are both installed on the frame 1.

[0054] like Figure 1 As shown, the frame 1 includes two support beams 11 , which are spaced apart along the front-to-back direction and extend along the left-to-right direction.

[0055] The function of the conveying device is to convey the food mold 4 from left to right, and it includes a connecting shaft 21 and two conveying units. There are two connecting shafts 21 spaced apart on the left and right. The connecting shaft 21 extends front and back, and both ends are respectively installed on two support beams 11. The two conveying units are spaced apart in the front and back directions, and the conveying units include a driving wheel 22 and a flexible chain plate 23. A driving wheel 22 is installed at both ends of each connecting shaft 21, and the flexible chain plate 23 is wrapped around the driving wheel 22. When in use, the food mold 4 is placed on the two flexible chain plates 23 and conveyed from left to right. In actual use, a plurality of baffles can be set on the flexible chain plate 23, and the baffles push the food mold 4 to move to the right to ensure that the food mold 4 will not move to the left after being subjected to a leftward thrust.

[0056] The structures of the frame 1 and the conveying device are both prior art and will not be described in detail here.

[0057] like Figures 3 to 12 As shown, the function of the air jet device is to blow out and collect the residue in the groove 41 of the food mold 4. The air jet device includes a base 31, an air jet module, an air extraction pipe 318, a first air pipe 324, and a second air pipe 328.

[0058] The base 31 includes a fixing plate 32 , a fixing box 33 , a U-shaped plate 34 , an adjustment component and an injection module mounting seat 35 . The fixing plate 32 includes vertical plates 36 respectively fixed on two support beams 11 and a horizontal plate 37 connecting the two vertical plates 36 .

[0059] The fixing box 33 opens downward and includes a first top plate 38, a first side plate 39, and a sealing plate 310. The first side plates 39 are arranged in parallel on the left and right sides, and the first top plate 38 is fixed on the top of the two first side plates 39. The sealing plate 310 is fixed to the front and rear ends of the first top plate 38 and the first side plates 39.

[0060] The U-shaped plate 34 is located inside the fixed box 33 and includes a second top plate 311 and a second side plate 312. The front and rear ends of the second top plate 311 are respectively fixed to the sealing plate 310, and the second top plate 311 is spaced apart from the first top plate 38 in the vertical direction. There are two second side plates 312 arranged parallel to each other on the left and right sides, and the second top plate 311 is fixed to the top of the two second side plates 312. The second side plate 312 is spaced apart from the first side plate 39 on the corresponding side in the left and right directions, and the second top plate 311 is spaced apart from the first top plate 38 in the vertical direction. The gaps at the two locations are connected and together form an exhaust channel 313. The exhaust channel 313 has an exhaust port at the bottom, and the exhaust port is formed by the bottom of the first side plate 39 and the second side plate 312.

[0061] The function of the adjusting component is to install the fixing box 33 on the fixing plate 32, and to adjust the height of the fixing box 33 and the U-shaped plate 34; the adjusting component includes an adjusting plate 314 and an adjusting bolt 315. The adjusting plate 314 is fixed to the outside of the sealing plate 310 and the first side plate 39, and the adjusting bolt 315 is rotatably assembled on the cross plate 37. The adjusting bolt 315 passes through the adjusting plate 314 and is threadedly engaged with the adjusting plate 314. After rotating the adjusting bolt 315, the adjusting plate 314, the fixing box 33, and the U-shaped plate 34 can be driven to move up and down.

[0062] The jet module mounting base 35 is fixed to the second top plate 311 and is used to mount the jet module. The jet module mounting base 35 comprises a plate body and multiple lug plates secured to the plate body. The front and rear ends of the plate body are secured to the cover plate 310. The multiple lug plates are spaced apart in the front-to-back direction. Each lug plate group includes two first lug plates 316 spaced apart in front and back, connected by a fixed shaft 317.

[0063] The exhaust pipe 318 is fixedly mounted on the horizontal plate 37. The lower end of the exhaust pipe 318 passes through the first top plate 38 and is movable relative to the first top plate 38. The exhaust pipe 318 is connected to the exhaust passage 313. When in use, the exhaust pipe 318 is connected to a negative pressure suction device to suck away the residue blown off the food mold 4.

[0064] There are multiple jet modules, each corresponding to one of the multiple lug plate groups. The jet modules include a first jet block 319, a second jet block 320, a first elastic member 321, a push mechanism, and a second elastic member 322. The first jet block 319 is rotatably mounted on a fixed shaft 317 about a longitudinal axis. The second jet block 320 is rotatably mounted at the bottom of the first jet block 319 about a longitudinal axis.

[0065] The first jet block 319 has a first jet port 323 facing downward to the left. A first air pipe 324 is mounted on the right side of the first jet block 319 and communicates with the first jet port 323. The first jet port 323 ejects air toward the left and downward, blowing any residue near the left side of the groove 41 away from the groove 41. The first jet block 319 includes two second lugs 325 at the bottom, spaced apart in the front-to-back direction. The bottom of the first jet block 319 also has guide grooves 326 extending left and right. The first jet block 319 also includes a mounting plate 332 at the right end of the bottom.

[0066] The first elastic member 321 is a torsion spring mounted on the exterior of the fixed shaft 317. Its two ends are connected to the fixed shaft 317 and the first air injection block 319, respectively. The first elastic member 321 is used to apply an elastic force to the first air injection block 319, causing it to swing leftward. In actual use, a first main pipe connecting each of the first air pipes 324 can be provided, extending through the base 31.

[0067] The top of the second air jet block 320 is rotatably mounted between the two second lugs 325. Specifically, blind holes can be provided in the second lugs 325, and protrusions can be provided on the second air jet block 320 to penetrate the blind holes. A second air jet port 327 is defined at the bottom of the second air jet block 320. A second air pipe 328 is mounted on the right side of the second air jet block 320 and communicates with the second air jet port 327. The second air jet port 327 sprays air toward the right side of the groove 41, removing any residue from the groove 41. In actual use, a second main pipe can be provided to connect the second air pipes 328 and extend through the base 31.

[0068] The function of the push mechanism is to drive the first jet block 319 to swing rightward, and at the same time drive the second jet block 320 to swing rightward relative to the first jet block 319. The push mechanism includes a guide rod 329, a sliding rod 330, an adjusting nut 331, and a gear transmission structure.

[0069] A guide rod 329 is fixedly mounted on a mounting plate 332 at the bottom of the first jet block 319 and extends leftward and rightward. A sliding rod 330 is slidably mounted in the guide slot 326 of the first jet block 319, with the right end of the sliding rod 330 slidingly fitting over the guide rod 329. The left end of the sliding rod 330 has an L-shaped force-bearing portion 333, which bends downward and extends leftward. The left end of the force-bearing portion 333 protrudes leftward from the first and second jet blocks 319 and 320.

[0070] The adjusting nut 331 is mounted on the guide rod 329 and is threadedly engaged with the guide rod 329. The second elastic member 322 is a compression spring, which is sleeved on the guide rod 329. The right end of the second elastic member 322 presses against the adjusting nut 331, and the left end of the second elastic member 322 presses against the sliding rod 330.

[0071] The gear transmission structure drives the second jet block 320 to swing rightward when the sliding rod 330 moves rightward, directing the second jet port 327 toward the right side of the groove 41. The gear transmission structure includes a first transmission tooth segment 334, an intermediate gear 335, and a second transmission tooth segment 336. The first transmission tooth segment 334 is located on the bottom surface of the sliding rod 330 and is a spur gear segment. The intermediate gear 335 is mounted on the bottom of the first jet block 319 and is rotatable about a longitudinal axis. Specifically, the intermediate gear 335 is located between the two second lugs 325. The second transmission tooth segment 336 is located on the top of the second jet block 320 and is a circular arc tooth segment, the centerline of which serves as the rotation axis of the second jet block 320.

[0072] The first transmission tooth segment 334, the intermediate gear 335, and the second transmission tooth segment 336 are arranged in sequence along the vertical direction. The first transmission tooth segment 334 and the second transmission tooth segment 336 respectively mesh with the top and bottom sides of the intermediate gear 335. When the sliding rod 330 and the first transmission tooth segment 334 move rightward, they drive the intermediate gear 335 to rotate, which in turn drives the second transmission tooth segment 336 and the second jet block 320 to swing rightward. When the sliding rod 330 moves leftward, it sequentially drives the first transmission tooth segment 334, the intermediate gear 335, and the second transmission tooth segment 336 to drive the second jet block 320 to swing leftward to reset.

[0073] In this embodiment, the first elastic member 321 has a higher deformation resistance than the second elastic member 322. When the sliding rod 330 is pushed rightward, it compresses the second elastic member 322, causing it to move rightward, thereby driving the second jet block 320 to swing rightward via the gear transmission structure. Simultaneously, the sliding rod 330 applies a rightward thrust to the first jet block 319 via the second elastic member 322, the adjustment nut 331, and the guide rod 329. This thrust drives the first jet block 319 to swing rightward. However, because the first elastic member 321 has a higher deformation resistance than the second elastic member 322, the second elastic member 322 is compressed first. Once compressed to a predetermined level, the thrust it imparts increases to a level sufficient to overcome the elastic force of the first elastic member 321, thereby driving the first jet block 319 to swing.

[0074] In this embodiment, Figure 9 、 Figure 11 As shown, the first air jet port 323 and the second air jet port 327 are both long ports, which extend in the front-to-back direction, and can increase the area covered by the airflow and enhance the effect of the air jet cleaning.

[0075] Usage process: In the initial state, the first jet block 319 is in a vertical state under the action of the first elastic member 321, and the second jet block 320 is in a vertical state under the action of the second elastic member 322, and the left end of the force-bearing part 333 is located below the top surface of the food mold 4.

[0076] The conveying device conveys the food mold 4 from left to right. The right side of the food mold 4 first pushes the left end of the force-bearing part 333, causing the second jet block 320 and the first jet block 319 to swing to the right, and the jet device is completely placed above the food mold 4. At this time, the first jet block 319 is in an avoidance state, and the second jet block 320 and the pushing mechanism will not affect the normal conveyance of the food mold 4.

[0077] The food mold 4 continues to move to the right. When the force-bearing portion 333 moves to the position of the groove 41, the force-bearing portion 333 is no longer subjected to the pushing force. The first air jet block 319 is reset under the action of the first elastic member 321, and the second air jet block 320 is reset under the action of the second elastic member 322. The force-bearing portion 333 of the sliding rod 330 and the bottom of the second air jet block 320 are both located in the groove 41. At this time, the first air jet block 319 is in a cleaning state, with the first air jet 323 facing the lower left and the second air jet 327 facing downward. The first air jet 323 sprays air toward the bottom and left portion of the groove 41, blowing the residue away from the groove 41.

[0078] The food mold 4 continues to move to the right. When the force-bearing part 333 hits the left groove wall of the groove 41, the sliding rod 330 moves to the right, driving the second jet block 320 to swing to the right relative to the first jet block 319 through the gear transmission structure. During the rightward swing, the second jet port 327 sprays toward the right side of the groove 41 to blow the residue away from the groove 41 to avoid dead corners in cleaning.

[0079] As the food mold 4 continues to move to the right, the sliding rod 330 continues to move to the right and compresses the second elastic member 322. Then, the first jet block 319 begins to swing to the right, and the second jet block 320 also swings to the top of the groove 41 with the first jet block 319. Finally, the force-bearing part 333 and the second jet block 320 are both swung out of the groove 41, and the first jet block 319 returns to the avoidance state.

[0080] After the residue is blown away from the groove 41 , it is separated from the groove 41 , and the exhaust pipe 318 can extract the residue through the exhaust channel 313 to prevent it from falling back into the groove 41 .

[0081] In actual use, before cleaning, the adjusting nut 331 is rotated according to the size of the groove 41. When the size of the groove 41 is small, the adjusting nut 331 is rotated to the left, and the initial compression of the second elastic member 322 is larger; when the size of the groove 41 is large, the adjusting nut 331 is rotated to the right, and the initial compression of the second elastic member 322 is smaller.

[0082] It should be noted that the "left", "right", "front" and "back" in this embodiment are only artificially defined directions for the convenience of description. They only represent relative positions and do not limit the specific structure.

[0083] In this embodiment, by providing a rotatable second air jet block 320, when the food mold 4 is conveyed to the right, the second air jet block 320 swings rightward, and the gas ejected from the second air jet port 327 impacts the right side of the groove 41, blowing away any residue adhering to the groove 41. Furthermore, in this embodiment, the left and right sliding motion of the sliding rod 330 not only drives the second air jet block 320 to swing rightward, but also drives the first air jet block 319 to swing out of the groove 41 and separate from the food mold 4. The first elastic member 321 drives the first air jet block 319 to swing back, returning the bottom of the second air jet block 320 and the sliding rod 330 to the next groove 41. The second elastic member 322 drives the second air jet block 320 to swing back to the right after the sliding rod 330 is pushed, spraying gas on the right side of the groove 41.

[0084] In the present invention, through the first jet block 319, the second jet block 320, the first elastic member 321, the second elastic member 322 and the pushing mechanism, the groove 41 in the food mold 4 is utilized to ensure that the right side of the groove 41 can be cleaned by jet cleaning without affecting the normal transportation of the food mold 4.

[0085] In this embodiment, the first elastic member 321 is a torsion spring disposed between the fixed shaft 317 and the first jet block 319. In other embodiments, the first elastic member 321 may be a compression spring disposed between the right side of the first jet block 319 and the jet module mounting base 35, which drives the first jet block 319 to swing leftward.

[0086] In this embodiment, the fixing box 33 is mounted on the fixing plate 32 via an adjustment plate 314 and an adjustment bolt 315 and can be adjusted up and down relative to the fixing plate 32. In other embodiments, a hydraulic cylinder, an air cylinder, an electric push rod, or other structures can be provided on the fixing plate 32 to drive the fixing box 33 to move up and down.

[0087] In this embodiment, the first top plate 38 and the second top plate 311 are spaced apart, and the first side plate 39 and the second side plate 312 are spaced apart, together forming an air extraction channel 313. In other embodiments, the base 31 can be a one-piece structure, with a hole formed inside the base 31 to form the air extraction channel 313.

[0088] In this embodiment, the first air jet 323 and the second air jet 327 are both long openings extending in the front-to-back direction. In other embodiments, the first air jet 323 and the second air jet 327 may be round openings. In order to allow the airflow to cover a larger area, multiple first air jets 323 and second air jets 327 may be provided.

[0089] In this embodiment, the pushing mechanism includes a guide rod 329 and an adjusting nut 331. By rotating the adjusting nut 331, the initial compression of the second elastic member 322 can be adjusted. In other embodiments, for food molds 4 of the same specifications, the adjusting nut 331 can be omitted, and the second elastic member 322 can be directly pressed against the mounting plate 332.

[0090] In this embodiment, the gear transmission structure includes a first transmission tooth segment 334, an intermediate gear 335, and a second transmission tooth segment 336. In other embodiments, the second transmission tooth segment 336 can be replaced with a gear fixedly mounted on the second injection block 320.

[0091] In addition, in the description of this specification, “a plurality of” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.
