Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a casing measuring rod device that can mark the length of casings. Background Technology

[0002] In the sausage casing processing industry, casing measurement is a crucial step in determining product quality and production efficiency. Currently, the mainstream measurement methods are divided into two categories: manual measurement and machine measurement. While manual measurement boasts advantages such as high accuracy and adaptability, meeting the measurement needs of both semi-finished and finished casings, it suffers from high operating costs, low efficiency, and difficulty adapting to large-scale production scenarios. Furthermore, it relies heavily on operator experience, making it prone to errors in bundle length due to human calculation mistakes. Machine measurement offers high speed, meeting the efficiency requirements of large-scale production and primarily suitable for semi-finished casing measurement. However, its measurement accuracy is only accurate to 0.1 meters, with a single casing error range of 0.01-0.09 meters. Accumulated errors can easily occur when bundling multiple casings. Additionally, the coding module of the machine cannot flexibly adapt to the measurement needs of high-value-added finished casings when selecting casings for bundling, limiting its applicability.

[0003] In the current technology, there is no device that can combine the accuracy advantage of manual measurement with the efficiency advantage of measurement machine. Moreover, there are common problems such as unclear length markings after casing measurement and difficulty in quickly selecting the appropriate length casing when fitting.

[0004] To address these issues, I have improved upon my patent (2022215096613) for a roller-type multi-channel casing measuring and coding machine by designing a casing measuring and coding rod device that can identify casing length. Utility Model Content

[0005] The purpose of this invention is to provide a casing measuring rod device that can identify casing length, so as to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model provides a casing length marking and hanging device, including an operating table. A variable speed motor is fixedly installed on one side of the operating table. Above the operating table surface, along the casing conveying direction, there is a pair of relatively movable front rollers and a pair of relatively movable marking rollers. The front rollers are used to adjust the stretch of the marked casings. The front rollers and marking rollers are connected to a transmission mechanism via gears, and the transmission mechanism is connected to the output end of the variable speed motor. A transmission wheel is coaxially fixed to one end of each marking roller. A roller-type distance meter is fixedly installed on the operating table at the position corresponding to the transmission wheel. The distance measuring roller of the roller-type distance meter is in close contact with the periphery of the transmission wheel. Above the operating table surface, the multi-channel casing conveying path has casing separators at the front rollers and marking rollers. Below the marking rollers, there is a casing collection box, a zone I hanging rod, and a zone II hanging rod.

[0007] Furthermore, one end of the operating table is equipped with an open casing collection box, which is located below the measuring roller. The casing collection box is divided into Zone I and Zone II by a collection box partition.

[0008] Furthermore, the casing collection box I is equipped with a hanging rod for measuring casings using the connector method, and the casing collection box II is equipped with a hanging rod for measuring and binding casings.

[0009] Furthermore, a water supply pipe with a control valve is fixedly connected to the upper side wall of the casing collection box, a drain valve for cleaning and drainage is installed at the bottom of the casing collection box, and a frame for installing the hanging rods in Zone I and Zone II is provided at the opening of the casing collection box.

[0010] Furthermore, the Zone I hanging rod is installed within Zone I of the casing collection box. Multiple Zone I hooks are spaced apart on the Zone I hanging rod, and each Zone I hook can hang several casings. The casing collection box frame is provided with fixing holes for securing the Zone I hanging rod. The Zone I hanging rod and the casing collection box can be movably or fixedly connected. A number combination turntable corresponding to the position of the Zone I hooks is installed on the Zone I hanging rod. The number combination turntable consists of three turntables, each marked with ten numbers from 0 to 9, and can rotate independently and freely.

[0011] Furthermore, the II-zone hanging rod is installed within the II-zone of the casing collection box. The II-zone hanging rod has a fixed length marker and ten II-zone hooks evenly distributed on it. Each II-zone hook can hang N casings. The II-zone hanging rod has a decimeter marker corresponding to the position of the II-zone hook, indicating the length of the casings hung by the II-zone hook in decimeters. The II-zone hanging rod is movably connected to the casing collection box via an interface end, which has a whole-meter marker indicating the length of the casings hung by the II-zone hook in whole meters.

[0012] Furthermore, the end of the II-zone hanging rod away from the II-zone hanging rod interface is a rounded end to make hanging sausage casings more convenient. There are multiple II-zone hanging rods, and the setting direction of the multiple II-zone hanging rods is perpendicular to the measuring roller.

[0013] Furthermore, casters with braking function are installed at the four corners of the bottom of the casing collection box.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, a variable speed motor drives the front roller and the measuring roller, and the transmission wheel at one end of the measuring roller drives the roller-type rangefinder. This not only retains the high efficiency advantage of the measuring machine, but also improves the measuring accuracy to a higher level than measuring machine and manual measuring. At the same time, because the casing connector method is used for measuring, it saves the equipment cost of the rangefinder assembly, hub and server required for measuring data acquisition and processing, and effectively avoids the cumulative error when multiple casings are used, thus solving the problem of difficulty in balancing efficiency and accuracy in the prior art.

[0015] 2. In this utility model, the I-zone hanging rod and II-zone hanging rod of the collection box can quickly, clearly and accurately mark the length of each group or each casing. After measuring and sizing several groups of casings using the joint method, the operator can quickly select the appropriate casing from the hook of the corresponding hanging rod. It is simple and easy to operate and is suitable for measuring and sizing semi-finished casings and high-value-added finished casings. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those of ordinary skill in the art without creative effort are all within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a casing length marking and hanging device, including an operating table 1, a variable speed motor 2 fixedly installed on one side of the operating table 1, a pair of relatively moving front rollers 3 and a pair of relatively moving measuring rollers 4 arranged sequentially above the surface of the operating table 1 along the casing conveying direction, the front rollers 3 are used to adjust the stretch of the measuring casing, the front rollers 3 and the measuring rollers 4 are connected to a transmission mechanism through gears, and the transmission mechanism is connected to the output end of the variable speed motor 2; a transmission wheel is coaxially fixed to one end of the measuring rollers 4, a roller-type rangefinder 5 is fixedly installed on the operating table 1 at the position corresponding to the transmission wheel, the measuring roller of the roller-type rangefinder 5 is in close contact with the outer periphery of the transmission wheel; a casing separator 6 is provided at the front rollers 3 and measuring rollers 4 respectively in the multi-channel casing conveying path above the surface of the operating table 1; a casing collection box 7, a zone I hanging rod 11 and a zone II hanging rod 15 are provided below the measuring rollers 4.

[0020] One end of the operating table 1 is equipped with an open casing collection box 7, which is located below the measuring roller 4. The casing collection box 7 is divided into Zone I and Zone II by a collection box partition 10. Zone I of the casing collection box 7 is equipped with a Zone I hanging rod 11 for measuring casings using the connector method, and Zone II of the casing collection box 7 is equipped with a Zone II hanging rod 15 for measuring casings with handles. A water supply pipe 8 with a control valve is fixedly connected to the upper side wall of the casing collection box 7. A drain valve 9 for cleaning and drainage is installed at the bottom of the casing collection box 7. The open end of the casing collection box 7 is equipped with a frame for installing the Zone I hanging rod 11 and Zone II hanging rod 15. Casters 20 with braking function are installed at the four corners of the bottom of the casing collection box 7.

[0021] The hanging rod 11 in Zone I is set in Zone I of the casing collection box 7. Multiple hooks 12 in Zone I are provided on the hanging rod 11 at intervals. Each hook 12 can hang several casings. The casing collection box 7 has a fixing hole 14 for the hanging rod in Zone I on its side. The hanging rod 11 in Zone I can be movably connected to the casing collection box 7 or fixedly connected through the fixing hole 14. The hanging rod 11 in Zone I is provided with a number combination turntable 13 corresponding to the position of the hook 12 in Zone I. The number combination turntable 13 consists of three turntables, each marked with ten numbers from 0 to 9, and can rotate independently.

[0022] The II-zone hanging rod 15 is set in the II-zone of the casing collection box 7. The II-zone hanging rod 15 is equipped with a fixed length mark. Ten II-zone hooks 16 are evenly arranged on the II-zone hanging rod 15. Each II-zone hook 16 can hang N casings. The II-zone hanging rod 15 is equipped with a decimeter mark 17 corresponding to the position of the II-zone hook 16. The decimeter mark 17 indicates the length of the casings hung by the II-zone hook 16 in decimeters. The II-zone hanging rod 15 is movably connected to the casing collection box 7 through the II-zone hanging rod interface end 19. The II-zone hanging rod interface end 19 is equipped with a whole meter mark 18. The whole meter mark 18 indicates the whole meter length of the casings hung by the II-zone hook 16. The end of the II-zone hanging rod 15 away from the II-zone hanging rod interface end 19 is a rounded end to make hanging casings more convenient. There are multiple II-zone hanging rods 15. The setting direction of multiple II-zone hanging rods 15 is perpendicular to the measuring roller 4.

[0023] Example 1: Multi-casing connector method for grading The so-called joint method of measuring sausage casing involves connecting the end of one sausage casing to the beginning of another during measurement. This reduces the error in accumulating the length after measuring a single sausage casing. Since the accuracy of existing sausage casing measuring machines is 0.1 meters, the error will inevitably increase when accumulating multiple casings. In this embodiment, multiple sausage casings are grouped together, and several groups of casings are measured simultaneously. The more groups, the higher the measurement efficiency.

[0024] The specific operating steps are as follows: 1. Move Zone I of the casing collection box 7 below the measuring roller 4 and lock the casters 20 of the casing collection box 7 to keep the water level of the casing collection box 7 at a reasonable height, and ensure that the water levels of Zone I and Zone II are connected.

[0025] 2. According to the processing requirements, group several sausage casings into a set, for a total of several sets. Place each set of casings sequentially on the casing separator 6 at the front roller for measurement. Then, take one casing from each set and pass it through the front roller 3 and then through another casing separator 6 to the measuring roller 4. Finally, adjust the starting end of the first casing in each set so that the starting ends of the first casings in all sets are synchronously located in the gap between the two measuring rollers 4. After the display of the roller rangefinder 5 is reset to zero, start the variable speed motor 2 to run slowly. When the measuring roller 4 is running, the front roller 3, the measuring roller 4, the transmission wheel of the measuring roller 4, and the measuring roller of the roller rangefinder 5 rotate synchronously. The speed of the variable speed motor 2 is adjusted according to the starting length of the measuring casings; that is, the speed can be faster for longer starting lengths and slower for shorter starting lengths to accommodate the jointing operation of two casings.

[0026] 3. When the first casing of a certain group is about to end at the front roller, connect it to the starting end of another casing in the same group, and then hang the tail end of the first casing on the corresponding hook 12 in Zone I, and so on.

[0027] 4. After the last sausage casing in a certain group has been measured, read the reading on the display screen of the roller rangefinder 5, and then rotate the corresponding number combination turntable 13 to determine the total length of the sausage casing in that group.

[0028] 5. After several sets of casings have been weighed, turn off the power to the variable speed motor 2 and the roller rangefinder 5 and wait for the handle to be replaced.

[0029] Example 2: Single-strand length marking and coding for multiple sausage casings The individual length marking and coding of multiple sausage casings is for casing matching. As described in Example 1, several groups of sausage casings have been marked and the total length of each group has been determined. Based on the difference between the total length and the standard length, it can be determined how long the next casing needs to be. Marking multiple casings and individually identifying the length of each casing lays the foundation for subsequent steps. In this example, several casings are grouped together, and the starting ends of each casing are aligned and marked. The number of identical casings is not limited, but generally at least five casings are grouped together to improve marking efficiency. The specific operation steps are as follows: 1. Move Zone II of the casing collection box 7 below the measuring roller 4 and lock the casters 20 of the casing collection box 7 to keep the water level of the casing collection box 7 at a reasonable height, and ensure that the water levels of Zone I and Zone II are connected.

[0030] 2. Group several casings with their starting ends aligned into a set, for a total of several sets. After aligning the starting ends of each set of casings, pass them sequentially through casing separator 6 → front roller 3 → casing separator 6 → measuring roller 4, ensuring that the starting ends of each casing in the several sets are simultaneously positioned in the gap between the two measuring rollers 4. First, reset the display of the roller rangefinder 5 to zero, then start the variable speed motor 2 to run slowly. When the measuring roller 4 is running, the front roller 3, measuring roller 4, the drive wheel of the measuring roller 4, and the measuring roller of the roller rangefinder 5 rotate synchronously. The speed of the variable speed motor 2 should be slower than that used in the multi-casing joint method, because in the joint method, the number of casings being measured simultaneously is the same as the number of sets of casings being measured simultaneously, meaning only one casing in a set is being measured. However, when measuring the length of multiple casings individually, the maximum number of casings being measured simultaneously is the sum of the total number of casings in all sets of casings being measured simultaneously.

[0031] 3. After measuring one of the casings in a series of sized casings, hang the casings corresponding to the data read from the display screen of the roller rangefinder 5 onto the hooks 16 of the corresponding length of the hanging rod 15 in section II. Continue this operation until all casings have been measured and hung.

[0032] 4. If you need to leave enough casings with length markings for casing assembly, you can repeat the above operation. If you are going to the casing assembly process, turn off the variable speed motor 2 and the roller rangefinder 5.

[0033] Example 3: Sausage Casing Preparation The term "casing bundle" refers to combining a set of casings into a bundle that meets the processing requirements. For example, the standard length of a bundle of finished casings is 91.5 meters, the minimum length of each casing is 2 meters (it cannot be shorter than 2 meters), the number of casings in each bundle cannot exceed 16, and the total length of each bundle has a tolerance of plus or minus 1 meter. Semi-finished casings have no restrictions on the number of casings in each bundle, but the minimum length requirements and total length requirements are slightly lower than those for finished casings. The steps for bundling semi-finished and finished casings are briefly described below: 1. Semi-finished sausage casings with handles When the semi-finished casings are measured and stacked to a length close to the standard length using the multi-casing method, they are hung one by one on the first hook 12 of the first hook 11 of the collection box 7. The casings closest to the difference in length within the allowable error range are selected from the second hook 16 of the second hook 15 of the collection box 7 to form a bundle of casings, because the number of casings in each bundle does not need to be considered for semi-finished casings.

[0034] 2. Finished sausage casings with handles According to the processing requirements of finished sausage casings, based on the total length of each bundle of casings, the starting length of each casing, and the maximum number of casings per bundle, first measure and weigh the casings using the multi-casing joint method. Then, hang each bundle in groups on hook 12 of section I of hanging rod 11 in collection box 7. While not exceeding the specified number of casings, reserve 1-2 casings for bundling. For example, if each bundle contains a maximum of 16 casings, then when 14 casings are measured, check if there is a single casing that can make up the difference within the error range. If so, combine them into one bundle. If the difference is too large, then search on hook 16 of section II of hanging rod 15 in collection box 7 and select two casings to bundle.

[0035] Another method for bundling finished sausage casings is to use the hooks 16 of the second section of the hanging rod 15 in the second section of the collection box 7, which has been marked with lengths, to bundle them by taking a shorter casing and then a longer casing, and repeating this process until a bundle of casings that meets the processing requirements is formed. This bundling method can make the most of short-sized casings and greatly improve economic efficiency.

[0036] Working principle: This invention utilizes a variable-speed motor 2 to drive a front roller 3 and a measuring roller 4 for casing transport. The measuring roller 4 drives a transmission wheel to rotate, and a roller-type distance meter 5 detects the casing length by contacting the transmission wheel, ensuring measurement accuracy. A casing separator 6 prevents casings from sticking or misaligning during transport. The casing collection box 7 is divided into Zone I and Zone II by a partition 10. A hanging rod 11 in Zone I indicates the total length of each set of casings, while a hanging rod 15 in Zone II indicates the length of a single casing, facilitating quick matching. A water supply pipe 8 ensures the normal water level in the collection box, and a drain valve 9 allows for draining excess water during cleaning. Casters 20 ensure the movement and positioning of the casing collection box 7, ultimately achieving a dual optimization of casing measurement efficiency and accuracy.

Any equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
