Description

Technical Field

[0001] This application relates to the field of drip irrigation tape embedded patch production technology, and in particular to a drip irrigation tape embedded patch dispensing device. Background Technology

[0002] In the production process of drip irrigation tape embedded patches, the feeding hopper is responsible for conveying plastic granules to the injection molding machine, which then performs thermoforming on the raw materials. After the molded material leaves the mold, it produces the target product embedded patch and plastic scrap. Currently, most material separating devices only separate the patch from the scrap through simple slit screening, which has significant drawbacks. On the one hand, because some scrap is similar in shape to the patch, it is easy to mix into the patch stream during the initial separation, resulting in incomplete separation. On the other hand, the separated patches may stick together or stack, affecting subsequent collection and processing. Traditional material separating devices lack secondary screening and processing mechanisms, making it difficult to meet the needs of high-precision production, resulting in inconsistent product quality, low resource recycling efficiency, and increased production costs and management difficulties for enterprises. Therefore, this paper proposes a material separating device for drip irrigation tape embedded patches. Utility Model Content

[0003] The purpose of this application is to provide a drip irrigation tape embedded patch dispensing device, which has the characteristics of high-precision material separation and effectively solves the problems of patch adhesion and stacking.

[0004] This application provides a drip irrigation tape embedded patch dispensing device with the following technical solution: it includes a dispensing mechanism, a scrap conveying mechanism, an embedded patch conveying mechanism, and a screening mechanism. The dispensing mechanism includes a material conveying mechanism, a recycling device, a slit at the end of the material conveying mechanism, and a strip of cloth on the surface of the recycling device. The screening mechanism includes a housing fixedly connected inside the support frame of the dispensing mechanism, a screening frame slidably disposed inside the housing, a screen fixedly installed inside the screening frame and disposed at the lower end of the slit, a motor frame fixedly fixed on the left side of the housing, and a forward and reverse motor mounted on the motor frame. The output end of the forward and reverse motor is rotatably connected inside the housing. A rotating rod is fixedly connected to the output end of the forward and reverse motor. A cam is fixedly disposed on the rotating rod. The cam cooperates with the lower surface of the screen. Slider blocks are disposed on both sides of the bottom of the screening frame. A groove is disposed on the inner wall of the housing to cooperate with the slider. A telescopic rod and a spring are fixedly connected to the lower surface of the slider. The spring is sleeved on the surface of the telescopic rod. The lower end of the spring and the telescopic rod are fixedly connected inside the groove.

[0005] By adopting the above technical solution, the material distribution mechanism achieves initial separation of materials through a material conveying mechanism, gaps, and a recycling device, blocking larger-sized scraps above the gaps and collecting them with the recycling device. In the screening mechanism, forward and reverse motors drive cams to vibrate in conjunction with the screen, and combined with the screen's screening function, perform secondary screening of the material passing through the gaps, ensuring the separation of qualified small-sized patches from scraps. The design of sliders, chutes, telescopic rods, and springs ensures the stability and reset capability of the screen during vibration, improving screening efficiency and accuracy, and achieving efficient separation of patches and scraps as a whole.

[0006] Preferably, the cloth strip is spirally wound around the surface of the recycling roller of the recycling device.

[0007] By adopting the above technical solution, the fabric strips are spirally wound around the surface of the recycling roller of the recycling device, increasing the contact area and friction between the recycling roller and the scrap. When the recycling roller rotates, the spirally wound fabric strips can more firmly drive the scrap to move, preventing the scrap from slipping or falling on the surface of the recycling roller, ensuring that the scrap is stably and efficiently transported to the guide shell, thereby improving the reliability and continuity of the scrap collection process.

[0008] Preferably, a guide shell is provided at the right end of the frame of the material distribution mechanism, and the outlet of the guide shell is located at the upper end of the scrap material conveying mechanism.

[0009] By adopting the above technical solution, the discharge port of the guide shell at the right end of the material distribution mechanism frame corresponds to the upper end of the scrap conveying mechanism. The guide shell provides a clear conveying path for the scrap, enabling the scrap conveyed by the recycling device to accurately enter the scrap conveying mechanism, preventing the scrap from scattering or shifting during the conveying process, improving the accuracy and efficiency of scrap collection, reducing the cleaning work caused by the scattering of scrap, and optimizing the entire material distribution process.

[0010] Preferably, the housing has no bottom plate, and the housing outlet is located at the upper end of the embedded patch conveying mechanism.

[0011] By adopting the above technical solution, the housing has no bottom plate and the discharge port corresponds to the upper end of the embedded patch conveyor mechanism. This design allows qualified patches after screening to fall directly and smoothly onto the conveyor belt of the embedded patch conveyor mechanism, avoiding patch residue or accumulation within the screening mechanism. The simple structural design reduces the patch conveying path and obstructions, improves patch collection efficiency, and ensures the smoothness of the qualified patch conveying process.

[0012] Preferably, the inner wall of the guide housing is provided with a smooth wear-resistant layer.

[0013] By adopting the above technical solution, the smooth and wear-resistant layer on the inner wall of the guide shell can effectively reduce the friction of scrap materials during the conveying process. On the one hand, it reduces the wear between the scrap materials and the inner wall of the guide shell, extending the service life of the guide shell; on the other hand, it allows the scrap materials to move more smoothly inside the guide shell, avoiding the scrap materials from getting stuck inside the guide shell due to excessive friction, thus ensuring the efficiency and stability of the scrap material conveying process.

[0014] Preferably, guide plates are provided on both sides of the upper surface of the frame of the material conveying mechanism. The guide plates are V-shaped, and the outlet ends of the two sets of guide plates are located on the surface of the conveyor belt of the material conveying mechanism.

[0015] By adopting the above technical solution, the V-shaped guide plates on both sides of the upper surface of the material conveying mechanism frame can converge and guide the material entering the material conveying mechanism. This concentrates and guides the dispersed material to the middle of the conveyor belt, allowing the material to move evenly into the gap, preventing material accumulation or deviation on the conveyor belt. This improves the accuracy and efficiency of material passing through the gap, laying a good foundation for subsequent material distribution operations and ensuring the orderly progress of the distribution process.

[0016] Preferably, the screening frame and the right end of the screen are located at the upper end of the scrap conveying mechanism, the screen is made of stainless steel, and the screen is inclined towards the scrap conveying mechanism.

[0017] By adopting the above technical solution, the screen is made of stainless steel, which has good wear resistance and corrosion resistance, and can withstand the friction of materials during the material distribution process and the erosion of the production environment, thus extending the service life of the screen and reducing equipment maintenance costs. The screen is inclined towards the scrap conveying mechanism, and in conjunction with the vibration of the screen, unqualified patches and small scraps that have not passed through the screen holes can automatically move towards the scrap conveying mechanism under the action of gravity and vibration, realizing the automatic discharge of unqualified materials, further improving the material distribution efficiency and the degree of automation.

[0018] Preferably, the conveyor belt of the embedded patch conveying mechanism is made of rubber and has anti-slip texture on its surface.

[0019] By adopting the above technical solution, the rubber conveyor belt of the embedded patch conveying mechanism has anti-slip textures on its surface, increasing the friction between the conveyor belt and the patch. During the conveying of qualified patches, it can effectively prevent the patches from sliding, shifting, or falling on the conveyor belt, ensuring that the patches are stably and accurately conveyed to the designated collection position, improving the accuracy and reliability of patch collection, and guaranteeing the stability and continuity of the entire material distribution device.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] This drip irrigation tape embedded patch dispensing device uses a screen in a screening mechanism to perform secondary screening of materials that have undergone initial separation through the gaps in the dispensing mechanism. Because scrap is large and patches are small, when the material falls onto the screen, a forward and reverse motor drives a rotating rod and cam to rotate. The cam engages with the lower surface of the screen, causing it to vibrate. Under this vibration, smaller, qualified embedded patches can pass smoothly through the screen holes and fall onto the upper surface of the embedded patch conveying mechanism, while larger, unqualified patches and scrap are intercepted. This achieves high-precision separation of patches and scrap, solving the problem of incomplete separation in traditional devices and effectively addressing patch adhesion and stacking issues. The screen is inclined towards the scrap conveying mechanism, and in conjunction with the slider, chute, telescopic rod, and spring at the bottom of the screening frame, driven by the vibration of the cam, unqualified patches and scrap that have not passed through the screen are quickly moved towards the scrap conveying mechanism and collected under the combined action of the inclined surface and vibration. This process not only avoids material accumulation on the screen, but also speeds up the screening process, greatly improves material distribution efficiency, and ensures smooth material distribution.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0030] Example 1: A drip irrigation tape embedded patch dispensing device, referring to Figure 1 , Figure 3 and Figure 4 The system includes a material distribution mechanism 1, a scrap conveying mechanism 2, an embedded patch conveying mechanism 3, and a screening mechanism 4. The material distribution mechanism 1 includes a material conveying mechanism 101, a recycling device 102, a slit 103 at the end of the material conveying mechanism 101, and a cloth strip 104 on the surface of the recycling device 102. The screening mechanism 4 includes a housing 401 fixedly connected inside the support frame of the material distribution mechanism 1, a screening frame 402 slidably disposed within the housing 401, a screen 403 fixedly installed within the screening frame 402 and disposed at the lower end of the slit 103, a motor frame 404 fixedly fixed to the left side of the housing 401, and a forward / reverse motor 405 mounted on the motor frame 404. The output end of the forward / reverse motor 405 is rotatably connected inside the housing 401. A rotating rod 406 is fixedly connected to the output end of the forward / reverse motor 405, and a cam 407 is fixedly disposed on the rotating rod 406. The lower surfaces of 407 and screen 403 are fitted together. Slider 408 is provided on both sides of the bottom of the screening frame 402. The inner wall of the housing 401 is provided with a groove 409 that cooperates with the slider 408. A telescopic rod 410 and a spring 411 are fixedly connected to the lower surface of the slider 408. The spring 411 is sleeved on the surface of the telescopic rod 410. The lower ends of the spring 411 and the telescopic rod 410 are fixedly connected inside the groove 409. The material distribution mechanism 1 achieves the initial separation of materials through the material conveying mechanism 101, the gap 103 and the recycling device 102, blocking larger-sized scraps above the gap 103 and collecting them by the recycling device 102. In the screening mechanism 4, the forward and reverse motor 405 drives the cam 407 to cooperate with the screen 403 to generate vibration. Combined with the screening function of the screen 403, the material passing through the gap 103 is screened a second time to ensure that qualified small-sized patches are separated from scraps. The slider 408, the groove 409, the telescopic rod 410 and the spring 411 ensure the stability and reset ability of the screen 403 during vibration, improve screening efficiency and accuracy, and achieve efficient separation of the sheet and scrap from the whole.

[0031] Reference Figure 1 and Figure 2The cloth strip 104 is spirally wound around the surface of the recycling roller of the recycling device 102. A guide shell 105 is provided at the right end of the frame of the material distribution mechanism 1. The outlet of the guide shell 105 is located at the upper end of the scrap conveying mechanism 2. The spiral wound cloth strip 104 increases the contact area and friction between the recycling roller and the scrap. When the recycling roller rotates, the spirally wound cloth strip 104 can more firmly drive the scrap to move, preventing the scrap from slipping or falling on the surface of the recycling roller, ensuring that the scrap is stably and efficiently conveyed to the guide shell 105, thereby improving the reliability and continuity of the scrap collection process. The outlet of the guide shell 105 at the right end of the frame of the material distribution mechanism 1 corresponds to the upper end of the scrap conveying mechanism 2. The guide shell 105 provides a clear conveying path for the scrap materials, enabling the scrap materials conveyed by the recycling device 102 to accurately enter the scrap material conveying mechanism 2, preventing the scrap materials from scattering or shifting during the conveying process, improving the accuracy and efficiency of scrap material collection, and also reducing the cleaning work caused by the scattering of scrap materials, thus optimizing the entire material distribution process.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The housing 401 has no bottom plate, and its outlet is located at the upper end of the embedded patch conveying mechanism 3. The inner wall of the guide housing 105 is provided with a smooth, wear-resistant layer. The absence of a bottom plate and the alignment of the outlet with the upper end of the embedded patch conveying mechanism 3 allow qualified patches, after being screened by the screen 403, to fall directly and smoothly onto the conveyor belt of the embedded patch conveying mechanism 3, preventing patch residue or accumulation within the screening mechanism 4. This simple structural design reduces the patch conveying path and obstructions, improves patch collection efficiency, and ensures the smoothness of the qualified patch conveying process. The smooth, wear-resistant layer on the inner wall of the guide housing 105 effectively reduces friction of scrap materials during conveying. On the one hand, it reduces wear between scrap materials and the inner wall of the guide shell 105, extending the service life of the guide shell 105; on the other hand, it allows scrap materials to move more smoothly inside the guide shell 105, avoiding excessive friction that could cause scrap materials to get stuck inside the guide shell 105, thus ensuring the efficiency and stability of the scrap material conveying process.

[0033] Reference Figure 1 , Figure 2 and Figure 3The material conveying mechanism 101 has guide plates 106 on both sides of the upper surface of the frame. The guide plates 106 are V-shaped. The outlet ends of the two sets of guide plates 106 are located on the surface of the conveyor belt of the material conveying mechanism 101. The right end of the screening frame 402 and the screen 403 are located on the upper end of the scrap conveying mechanism 2. The screen 403 is made of stainless steel and is inclined towards the scrap conveying mechanism 2. The conveyor belt of the embedded patch conveying mechanism 3 is made of rubber and has anti-slip texture on the surface. The V-shaped guide plates 106 on both sides of the upper surface of the frame of the material conveying mechanism 101 can converge and guide the material entering the material conveying mechanism 101. Dispersed materials are concentrated and guided to the middle of the conveyor belt, allowing them to move evenly towards the gap 103. This prevents material accumulation or deviation on the conveyor belt, improving the accuracy and efficiency of material passage through the gap 103 and laying a good foundation for subsequent material distribution operations. It ensures the orderly progress of the material distribution process. The screen 403 is made of stainless steel, possessing excellent wear and corrosion resistance, capable of withstanding material friction and environmental erosion during distribution, extending its service life and reducing equipment maintenance costs. The screen 403 is inclined towards the scrap conveying mechanism 2. Combined with the vibration of the screen 403, defective patches and small scraps that do not pass through the screen holes are automatically moved towards the scrap conveying mechanism 2 under the action of gravity and vibration, achieving automatic discharge of defective materials and further improving distribution efficiency and automation. The rubber conveyor belt surface of the embedded patch conveying mechanism 3 has anti-slip textures, increasing the friction between the conveyor belt and the patches. During the process of conveying qualified patches, it can effectively prevent the patches from sliding, shifting or falling on the conveyor belt, ensuring that the patches are stably and accurately conveyed to the designated collection position, improving the accuracy and reliability of patch collection, and ensuring the stability and continuity of the entire material distribution device operation.

[0034] In this embodiment, the material after initial separation by the gap 103 of the material distribution mechanism 1 is screened a second time by setting the screen 403 in the screening mechanism 4. Since the scrap is large and the pieces are small, when the material falls to the screen 403, the forward and reverse motor 405 drives the rotating rod 406 and the cam 407 to rotate. The cam 407 cooperates with the lower surface of the screen 403, causing the screen 403 to vibrate. Under vibration, smaller, qualified embedded patches can smoothly pass through the sieve holes of screen 403 and fall onto the upper surface of the embedded patch conveying mechanism 3, while larger, unqualified patches and scraps are intercepted, achieving high-precision separation of patches and scraps. This solves the problem of incomplete separation in traditional devices and effectively addresses the issues of patch adhesion and stacking. Screen 403 is inclined towards the scrap conveying mechanism 2. In conjunction with the slider 408, chute 409, telescopic rod 410, and spring 411 at the bottom of the screening frame 402, driven by the vibration of cam 407, unqualified patches and scraps that fail to pass through screen 403 will quickly move towards the scrap conveying mechanism 2 and be conveyed and collected under the combined action of the inclined surface and vibration. This process not only avoids material accumulation on screen 403 but also accelerates the screening rhythm, significantly improves material distribution efficiency, and ensures a smooth material distribution process.

[0035] The implementation principle of this application embodiment is as follows: After the injection molding machine discharges the hot-melt molded material, the material first enters the material conveying mechanism 101 of the material distribution mechanism 1. Guided by the V-shaped guide plates 106 on both sides of the upper surface of the material conveying mechanism 101 frame, the material converges towards the middle and moves along the conveyor belt of the material conveying mechanism 101 to the end gap 103. Since the scrap material is larger in size and the patch is smaller in size, the smaller patch can fall through the gap 103, while the larger scrap material is blocked above the gap 103; the blocked scrap material slides down to the surface of the recycling roller of the recycling device 102 under the action of gravity. Since the cloth strip 104 is spirally wound on the surface of the recycling roller, the friction between it and the scrap material is increased. When the recycling roller rotates, the cloth strip 104 drives the scrap material to move along the surface of the recycling roller, and through the guide shell 105 at the right end of the material distribution mechanism 1 frame, the scrap material is conveyed to the upper end of the scrap material conveying mechanism 2, and finally collected by the scrap material conveying mechanism 2. The smooth, wear-resistant layer on the inner wall of the guide shell 105 reduces resistance during the conveying of scrap materials, ensuring smooth transport. The patch falling through the gap 103 lands on the screen 403 of the screening mechanism 4. At this time, the forward and reverse motors 405 mounted on the motor frame 404 start, and the output end of the forward and reverse motors 405 drives the rotating rod 406 to rotate, causing the cam 407 on the rotating rod 406 to rotate accordingly. Because the cam 407 engages with the lower surface of the screen 403, the cam 407 intermittently lifts the screen 403 during rotation, causing the screen 403 to vibrate. The sliders 408 on both sides of the bottom of the screen 403 slide within the groove 409, working in conjunction with the telescopic rod 410 and the spring 411 to buffer and assist in the reset of the screen 403. Under the vibration of the screen 403, on the one hand, the adhesive force between the patches caused by the residual adhesive substances from the hot melt is broken, and the patches that are stuck together are dispersed; on the other hand, qualified small-sized patches pass through the screen holes of the screen 403 and fall into the embedded patch conveying mechanism 3 below. Since the screen 403 is inclined towards the scrap conveying mechanism 2, the scraps on the screen 403 that do not pass through the screen holes will move towards the scrap conveying mechanism 2 under the action of vibration and the inclined surface, and will eventually be conveyed to the scrap conveying mechanism 2 for collection; the qualified patches that fall into the embedded patch conveying mechanism 3 are conveyed by a conveyor belt made of rubber with anti-slip texture on the surface. The anti-slip texture increases the friction between the patch and the conveyor belt, ensuring that the patch will not slip during the conveying process and is stably transported to the designated location for collection, thereby completing the efficient separation and collection process of the embedded patch and scrap material of the drip irrigation tape.
