[0002] The Talalay process is a special latex production technology that uses vacuum and freezing to expand and evenly distribute the latex, then injects carbon dioxide to make the latex begin to gel, then solidifies it at high temperature, and finally washes and dries it.

[0003] Crushed latex pillows are made of crushed latex particles. The gaps between the particles help air flow, making the pillow more breathable. This helps reduce moisture and stuffiness, and improves sleep comfort. As the raw material for crushed latex pillows, Talalay latex has natural advantages such as non-toxicity, antibacterial and anti-mite, and anti-allergic, which meets the needs of modern consumers for environmental protection and health.

[0004] However, due to its high elasticity and flexibility, Talalay latex will deform during the cutting process due to rebound resilience, making the cutting less precise or producing an uneven cutting surface, resulting in an uneven cutting surface or different particle sizes. During the cutting process, the latex material will be compressed due to the pressure of the cutter, and when the cutter is removed, the material will rebound. This compression and rebound process will cause uneven cutting edges and affect the uniformity of cutting. The uneven cutting surface or different particle sizes of Talalay crushed latex particles will directly affect the user experience.

[0041] like Figure 2 and Figure 3 As shown, the slicing unit 200 includes: a circular cutting unit 210, and a plurality of supporting units 220 respectively arranged on the upper side and the lower side of the circular cutting unit 210, the plurality of supporting units 220 are arranged on the same vertical line, and the plurality of supporting units 220 are used to fix and adjust the position of the Talalay latex block, the circular cutting unit 210 includes a circular cutting base 211, a circular cutting cylinder 212 arranged on the circular cutting base 211, and a wire cutting unit 213 arranged on the circular cutting cylinder 212, the circular cutting base 211 is fixedly connected to the frame 100, the circular cutting cylinder 212 is used to control the horizontal circular motion and horizontal linear motion of the wire cutting unit 213, the circular cutting base 211, the circular cutting cylinder 212 and the wire cutting unit 213 are located on the same horizontal plane, and the wire cutting unit 213 is used to slice the Talalay latex block;

[0042] The transfer unit 300 is used to drive the sliced ​​Talalay latex block to move linearly and to perform cold treatment. The linear movement direction of the sliced ​​Talalay latex block is horizontally set from the slice unit 200 to the plurality of pelletizing units 400.

[0043] A plurality of pelletizing units 400 are used to pelletize the sliced ​​Talalay latex blocks.

[0044] The circular cutting base and the circular cutting cylinder in the slicing unit respectively drive the wire cutting unit to perform circular motion and linear motion, so that the Talalay latex block is sliced ​​in a circular manner, and the Talalay latex block is sent to the pelletizing unit for processing after being cold-treated. The cutting force generated by the circular motion and the linear motion can make the Talalay latex block slices have a smooth cross-section. The cold treatment can improve the hardness of the Talalay latex block slices, reduce deformation and displacement during cutting, ensure uniform and smooth pelletizing, and solve the defects of uneven cross-section and different particle sizes caused by cutting Talalay latex blocks in the prior art.

[0045] like Figure 4 As shown, each support unit 220 includes: a support cylinder 221, a support cylinder rod 222 fixedly connected to the support cylinder 221, and a support plate 223 fixedly connected to the support cylinder rod 222, the support cylinder 221 is fixedly connected to the frame 100, the support cylinder 221, the support cylinder rod 222 and the support plate 223 are located on the same vertical line, adjacent support units 220 are symmetrically distributed about the horizontal plane, the support cylinder rod 222 drives the support plate 223 to move vertically, the support cylinder 221 provides power to the support cylinder rod 222, and a fixing clamp is arranged on the support plate 223, and the fixing clamp is used to fix the Talalay latex block.

[0046] The adjacent support units 220 are symmetrically distributed about the horizontal plane to accurately fix and adjust the position of the Talalay latex block. This precise control ensures the stability of the latex block during the cutting process, thereby helping to obtain a smooth cutting surface. The support cylinder rod 222 drives the support plate 223 to move vertically, which helps to apply uniform pressure to the latex block during the cutting process and reduce the uneven cutting surface caused by uneven pressure.

[0047] The circular cutting cylinder 212 includes a guide rail base, and a guide rail motor, a centripetal cylinder and a centripetal cylinder rod respectively fixedly arranged on the guide rail base. The circular cutting base 211 is provided with an annular guide rail, the guide rail base is clamped with the annular guide rail, the guide rail motor provides power to the guide rail base and drives the guide rail base to perform circular motion, the centripetal cylinder rod is fixedly connected to the wire cutting unit 213, and the centripetal cylinder provides power to the centripetal cylinder rod. The guide rail base drives the wire cutting unit 213 to perform circular motion, and the centripetal cylinder drives the wire cutting unit 213 to perform linear motion, so that the wire cutting unit 213 can gradually perform linear motion during the circular motion process, and can make the cutting force generated during cutting always point to the center of the annular guide rail, which helps to reduce the deviation of the force during the cutting process, thereby reducing the unevenness of the cutting surface and the inconsistency of the size, so as to form a flat and horizontal surface.

[0048] The wire cutting unit 213 includes a slicing motor and a cutting line arranged on the slicing motor. The slicing motor provides power for the cutting line. The slicing motor drives the cutting line to perform horizontal reciprocating vibrations. The reciprocating vibration direction coincides with the axial direction of the cutting line. The reciprocating vibration direction is perpendicular to the circular motion axis of the wire cutting unit 213. The wire cutting unit 213 drives the cutting line to perform horizontal reciprocating vibrations through the slicing motor. The reciprocating vibration direction coincides with the axial direction of the cutting line. The stable cutting of the Talalay latex block can be maintained during the linear motion of the wire cutting unit, thereby improving the stability and efficiency during slicing. The reciprocating vibration direction is perpendicular to the circular motion axis of the wire cutting unit 213. This arrangement helps to reduce the stress concentration on the Talalay latex block during the cutting process. Reducing stress concentration can reduce deformation during the cutting process, thereby improving the flatness of the cutting surface and the uniformity of the particle size.

[0049] The transfer unit 300 includes: a transfer component, and a cooling component arranged on one side of the transfer component, the transfer component includes a transfer guide rail, a transfer base engaged with the transfer guide rail, a plurality of transfer cylinders connected to the transfer base, and a fixed plate connected to the plurality of transfer cylinders, a transfer motor is arranged on the transfer base, the transfer motor drives the transfer base to move along the transfer guide rail, the transfer guide rail is fixedly arranged on the frame 100, and a plurality of transfer cylinders drive the fixed plate to move vertically.

[0050] The cooling assembly includes a water spray assembly and a cooling module arranged on one side of the water spray assembly, the cooling module is located between the water spray assembly and the pelletizing unit 400, the water spray assembly and the cooling module are located on the same horizontal plane, and are located above the transfer assembly. Better crystal morphology and particle size distribution can be obtained through temperature control, and the coordinated work of the water spray assembly and the cooling module can accurately control the temperature of the latex block, thereby helping to obtain a smoother cutting surface and a more uniform particle size. The method of first spraying water and then cooling allows the Talalay latex block to be evenly cooled, which can ensure that the temperature of the entire latex block is consistent during the cutting process, and helps to maintain the uniformity of the particle size.

[0051] like Figure 5 As shown, each pelletizing unit 400 includes: a pelletizing motor 410, a pelletizing shaft 420 connected to the pelletizing motor 410, and a plurality of pelletizing circular knives 430 fixedly arranged on the pelletizing shaft 420. The pelletizing motor 410 is fixedly connected to the frame 100, and the pelletizing shaft 420 is horizontally arranged. The pelletizing motor 410 drives the pelletizing shaft 420 to rotate. The plurality of pelletizing circular knives 430 on each pelletizing shaft 420 are linearly arranged on the pelletizing shaft 420, and the distribution axis coincides with the axis of the pelletizing shaft 420. Adjacent pelletizing units 400 are located on the same vertical plane and adjacent pelletizing shafts 420 are arranged in parallel. The plurality of pelletizing circular knives 430 on adjacent pelletizing units 400 are respectively staggered. The rotation directions of adjacent pelletizing shafts 420 are opposite and the rotation directions of adjacent pelletizing shafts 420 near each other are away from the cooling assembly. The plurality of pelletizing circular knives 430 on adjacent pelletizing units 400 are staggered, and this staggered layout can optimize cutting dynamics, reduce vibration and impact during the cutting process, and help improve the flatness of the cutting surface. The adjacent pelletizing line shafts 420 rotate in opposite directions, and the rotation direction of the adjacent pelletizing line shafts 420 near each other is away from the cooling assembly, which can generate a pulling force on the Talalay latex block and improve the cutting efficiency of the Talalay latex block.

[0052] A method for using a pelletizing device for crushed latex particles of a Talalay crushed latex pillow comprises the following steps:

[0053] S1: Place the Talalay latex block on the support unit 220 and fix and adjust the position to the required cutting position, start the circular cutting unit 210 to perform circular cutting on the Talalay latex block to obtain Talalay latex block slices; the Talalay latex block is placed on the support unit 220 and fixed and adjusted, which helps to ensure that the starting position of each cutting is accurate and consistent, thereby improving the flatness of the cutting surface. The circular cutting unit 210 performs circular cutting on the latex block, and this cutting method helps to maintain the consistency of the cutting depth and reduce the surface unevenness caused by different cutting depths.

[0054] S2: placing the Talalay latex block slices in S1 on a transfer base, starting the transfer motor to drive the Talalay latex block slices to pass through the water spray component and the cooling module in turn, and undergoing water spraying and cooling treatment in the process to obtain pre-treated Talalay latex block slices.

[0055] S3: Start the transfer cylinder and control the fixed plate to descend until the pretreated Talalay latex block slices in S2 are firmly pressed. The extrusion part is the tail of the pretreated Talalay latex block slices. Start the transfer motor to send the head of the pretreated Talalay latex block slices into the pelletizing unit 400 for pelletizing. During the contact process between the pretreated Talalay latex block and the pelletizing unit 400, adjust the transfer base speed to generate internal stress in the pretreated Talalay latex block slices. By adjusting the transfer base speed to generate internal stress in the pretreated latex block slices, the control of this internal stress helps to maintain the stability of the material during the cutting process and reduce the unevenness of the cutting surface caused by the release of internal stress.

[0056] S4: When the slicing and pelletizing process of the pre-treated Talalay latex block reaches 70%-80%, start the transfer cylinder to control the fixed plate to rise, and release the squeeze of the fixed plate on the pre-treated Talalay latex block slices until the pelletizing is completed. The size of the Talalay latex particles is 1-2cm. When the pelletizing process reaches 70-80%, gradually release the squeeze of the fixed plate on the latex block slices. This method of gradually releasing pressure helps to reduce stress concentration during the cutting process and avoid uneven cutting surfaces caused by stress concentration.

[0057] The moisture content of the Talalay latex block slices in S2 after passing through the water spray assembly is 20-40%, and the temperature of the Talalay latex block slices after passing through the cooling module is -20~-10℃. Appropriate moisture content helps to control the hardness and elasticity of the latex, reduce deformation during cutting, and improve the flatness of the cut surface. At the same time, the appropriate moisture content also helps to reduce friction and wear during the cutting process, further improving the cutting quality. A lower pelletizing temperature is conducive to maintaining a higher melt strength of the parison, reducing the phenomenon of parison sagging caused by excessive temperature, and causing uneven longitudinal wall thickness of the parison. For Talalay latex blocks, this means that surface unevenness and uneven size caused by thermal degradation can be reduced during the cutting process.

[0058] During pelletizing in S3, the speed of the transfer base is adjusted to stretch the Talalay latex block slices with a stretching amplitude of 1.1-1.2. Pre-stretching can be formed at the beginning of pelletizing, which can make the latex block slices more stable during the cutting process and reduce the uneven cutting caused by the internal stress of the latex block. This pre-stretching helps the latex block slices maintain uniform tension during cutting, thereby improving the flatness of the cut surface. Pre-stretching can reduce the resilience of the latex block slices during the cutting process, making it easier for the cutting line to penetrate the latex block, improving cutting efficiency, and reducing surface unevenness caused by changes in cutting resistance. Pre-stretching allows the latex block slices to have a certain deformation before pelletizing, which helps to reduce the size variation caused by the different internal structures of the latex block during the cutting process, making the cut particles more uniform in size.

[0107] Embodiment 9

[0108] This embodiment specifically discloses a pelletizing process for crushed latex particles used in Talalay crushed latex pillows, and the process steps are as follows:

[0109] S1: placing a Talalay latex block on the support unit 220 and fixing and adjusting the position to the required cutting position, starting the circular cutting unit 210 to perform circular cutting on the Talalay latex block to obtain Talalay latex block slices;

[0110] S2: Place the Talalay latex block slices in S1 on the transfer base, start the transfer motor to drive the Talalay latex block slices to pass through the water spray component and the cooling module, and undergo water spraying and cooling treatment in the process to obtain pre-treated Talalay latex block slices.

[0111] S3: Start the transfer cylinder, control the fixed plate to descend until the pre-treated Talalay latex block slices in S2 are firmly pressed, the extrusion part is the tail of the pre-treated Talalay latex block slices, start the transfer motor to send the head of the pre-treated Talalay latex block slices into the pelletizing unit 400 for pelletizing, and during the contact process between the pre-treated Talalay latex block and the pelletizing unit 400, adjust the transfer base speed to make the pre-treated Talalay latex block slices produce internal stress, and during pelletizing, adjust the transfer base speed to stretch the Talalay latex block slices, and the stretching amplitude is 1.25;

The target particle size of the pelletizing is 2 cm.

[0113] Comparative Example 1

[0114] The Talalay latex block is directly fed into the pelletizing unit 400 until the pelletizing target particle size is 2 cm.

[0115] Take 50 Talalay latex block pellets from each of Examples 1 to 9 and Comparative Example 1, and use a vernier caliper to measure the size of the Talalay latex block pellets. Each pellet is rotated in different directions and measured 3 times. The size of the Talalay latex block pellets is measured by taking the average of the three measurements, and the average is used as the size of the Talalay latex block pellets. The standard deviation of several Talalay latex block pellets from the same sample source is calculated, and the standard deviation data is shown in Table 1.

[0116] Table 1 Standard deviation data of Talalay latex block pelletizing in Examples 1 to 9 and Comparative Example 1

[0117]

[0118] It can be seen from Table 1 that the standard deviations of Examples 1 to 9 are all smaller than the standard deviation of Comparative Example 1, that is, the uniformity of pelletizing the Talalay latex block in Examples 1 to 9 is greater than the uniformity of Comparative Example 1.

[0119] In Examples 1 to 5, as the moisture content of the Talalay latex block slices gradually increases after passing through the water spray assembly, the standard deviation first decreases and then increases. This is because the Talalay latex block is sprayed with water and cooled successively, so that the Talalay latex block is evenly cooled, which can ensure that the temperature of the entire latex block is consistent during the cutting process and maintains a certain hardness, and can avoid deformation of the Talalay latex block during pelletizing, which helps to maintain the uniformity of the particle size; but when the water content is too high and the Talalay latex block slices are frozen, too many ice crystals are generated inside, resulting in pelletizing obstacles during pelletizing, which in turn reduces the pelletizing accuracy. The preferred embodiment is Example 3.

[0120] In Example 3 and Examples 6 to 9, as the stretching amplitude of the Talalay latex block slices gradually increases, the standard deviation first decreases and then increases. This is because in the initial stage of stretching, the material uniformity of the Talalay latex block slices themselves is good, and the mechanical properties of each part are similar. Therefore, when subjected to uniform stretching, each part can respond to the stretching force more consistently, resulting in a more uniform overall deformation, and the arrangement of water molecules in the latex in the ice crystals is relatively orderly, which to a certain extent enhances the integrity and uniformity of the material; as the stretching amplitude increases, the temperature distribution inside the Talalay latex block slices is uneven due to frictional heat generation, and the uneven temperature causes the mechanical properties of the material to change, which in turn affects the uniformity and standard deviation of the stretching, causing the standard deviation of the measured data to increase. The preferred embodiment is Example 7.

[0121] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
